You can even see at around 23:50 that when he hits the boards with the nunchucks, the board bounces BACK UP, because that 'tennis match- of forces wasn't allowed to be completed, and left energy in the board for it to 'hit the tennis ball' so to speak. Whereas with the stick, you can clearly see how the follow through absolutely DESTROYS the board- the deformation is so severe the wood noticably shatters and splinters.
Probably the best example to show all the principles you've mentioned in a clearly visibly way (as opposed to a very heavy, stationary humanoid target), and show just how inefficient the nunchucks are at transferring energy. The cantaloupe in the next example also does the same, albeit to a much lesser extent likely due it's weight. The follow through allowed the stick to overcome the springiness of the cantaloupe and actually deform it, little by little over the duration of the strike, until it was completely smashed, unlike the nunchucks. You can even see he tried to follow through on the strike with both the nunchucks and the stick, so that isn't the problem.
@@ravoniesravenshir3926 Well, there'd be more mass and he'd have to compare it to a quarter staff (assuming we're using the full 3 sections and not just whacking with the ends), but there'd be 2 points in which the chain of kinetic force is broken instead of 1. I wouldn't mind seeing it, but I don't imagine it'd change anything.
@@Skillfullfilms89 That's also a part of the advantage of chain / flail weapons - they remove the hand shock from the impact. Remember these were designed as TOOLS to use all day and then repurposed to the battlefield. I've used simple stick and flail type threshers - that chain and the removal of the hand shock makes a HUGE difference after a few hours.
I disagree. I opened the video to see how long it is and there is no way this video needs to be 26 minutes long. It is very well boring, a joke gone too far.
@@IIARROWS It's no joke, it's a topic of interest that people can like enough to discuss for long periods of time. I love the manga One Piece enough to watch multiple 4 hour videos of it. Is that boring? Well, not to me. So this is just not your cup of tea and that's ok.
I once conducted an experiment on how hard a nunchuck hits... the problem is that I don't remember what happened other than I woke up in the hospital a few hours later
Thanks for the mention, Shad. Your point about two-handed wielding and potential leverage advantage/kinetic linkage/enhanced control of the flute/stick is well worth investigating, so the Wushu Scientist and I accept your research proposal. We will repeat the tests using two-handed striking techniques and see what kind of results we get.
What I wonder about is using less than maximum force. For a stick, the force you put in and the force you get out is fairly linear (I'm assuming; could be wrong). However, is the same true for a nunchuck? It feels like you can get a faster acceleration for lower input force, at least up to a certain level, and I wonder how much effect that has on the strike force. Would that potentially generate enough force to be an effective weapon, or would it still be too little?
Yes that's what we need. Actual science, testing, numbers. My instincts say shad is right but we all know our instincts are dumb (at least we should) and you should never trust them which is why we do science. Reading up on what parts of an impact do damage would also be good. In crash testing you often talk about jerk as well so that might be an avenue of investigation.
Actually, for the stick, you get to add in the mass of your whole arm and some of the rest of your body too depending on how you swing it. Even with one a handed swing.
Yep haha, I love that it has gone so far now that we are down to the nitty gritty science behind the mechanics, to explain why the stick is simply a better weapon lol.
@@XBullitt16X sadly he doesn't yet talk about torque or angular momentum. What they learn at australian school? Angular momentum would be a very good topic to address to be honest. As would be the physical pendulum created by impact in the moment of transferral.
Your mention of the targets being springy has given me an idea on how to improve nunchucks. What if we removed one stick from the stick and string, made the stick which is still attached to the string more _springy_ and then connected the string to the top and bottom of the stick to make an arch. Then we sharpen the detached stick, place it on the string, pull back the string to make the now springy other half of the nunchuck bend, then we release the string and sharpened stick, and it will be launched forwards at high speeds! We have now created a superior ranged version of nunchucks, created using very similar materials of 2 sticks and a bit of string. You're welcome. It's suspiciously similar to my improved version of the throwing knife, but I'm sure that's just coincidence.
The mental gymnastics of fanboys are infinite. This probably won't ever end. I still see new comments about Shad's hit pieces on nunchuks on other channels to this day.
@Part-Time Gamer where the did you get that from? Of course the nunchucks could severely harm? No one has ever said they could not. The reason that weapon gets a fair bit of hate is because it is one of, if not the weakest weapon. Even a regular stick of same size/dimensions is more dangerous, and easier to use for that matter. It is still a weapon that can severely damage or kill, of course. But compared to pretty much all other weapons, it’s an awful weapon.
Ive practiced nunchucks casually for about 8 years. Pros -great dexterity/hand eye coordination trainer -forearm workout -its an exotic weapon that's rarely used. Many won't know its true weaknesses unless they've studied. Flaws -blocking with this weapon is not advised, dodging required. -danger to yourself. -unless it hits at full length and follows through, this weapon bounces and loses control easily. -cheap pairs are unreliable and break easy. -practice required outweighs actually combat effectiveness. -the weapon is utterly useless against anything lengthy or heavy. In the end they're great weapons to practice and condition your body for superior, more reliable weapons. You can only use them in combat if you have a reliable pair that lasts, if you're trained in many different strikes/transitions and if you literally have nothing else in reach.
When this whole thing started I was taking a dynamics class so I worked it out from that perspective. Because there was so much debate as to how much force was transferred, I just assumed perfect transfer for both, and even then the result was pretty conclusive- A nunchuck with the same mass would have to move not just moderately faster, but **much** faster (>2x iirc) to make delivery of the same energy even theoretically possible.
In the original Battle Royale movie, kiriyama kills a small group of kids and goes through their stuff. He pulls out a pair of nunchucks and just tosses them away. Thought youd appreciate that
I don't care about weapons or medieval stuff, nor really any subject on your channel. Yet I keep finding myself watching more videos. Maybe your unapologetic passion for what you do... keep it up. Very entertaining 👏
Nerds excitedly talking about their hobby always engages me. I don't care if it's some 1960s football cards, stamps, comics, space flight, whatever. The passion from the person always impresses me and hey, getting to learn some new information on a niche topic can't be bad.
I'd say the _one_ advantage of nunchaku is the inconspicuousness - _that they had when they were first used as weapons instead of farming tools._ It's like the walking cane effect (or umbrella would be an even better example nowadays since walking sticks are pretty unusual in most 'environments') - nobody sees it as a weapon since nobody _uses_ it as a weapon, and it has a completely different usage that everyone employs, so everyone sees "anti-rain tool" instead of "thin stick sturdy enough for one or two fairly hard strikes".
Was looking for this comment. In addition it should be remembered that they were flails used for threshing. That is repeatedly whacking rice, wheat and so on to separate the edible part of the grain from the straw and chaff. You can do this with a stick, but by using a flail less of the energy is fed back into your hand and arm. So that flexible joint isn't there to increase power but to make it easier on the user. If all you use it for is hitting people it's not the optimal weapon by far, and a stick is going to do more damage. Some mean the joint makes it a more flexible weapon. Well yea, but even so it's not really that impressive. What it does better than a stick is conceal a four foot long stick. Nunchucks are a lot shorten when folded up. All in all I'd say there are situations when they can be a better choice than a stout stick, but usually that's because you can't have a stout stick... If all you care about is efficiency, protection and damage the stick will win.
@@Predator20357 _"walking stick as well which won’t draw attention at all"_ Have you been outside any time during the last century or so? How many people with walking sticks have you seen? Walking sticks _will_ draw attention (except in pretty specific situations such as mountain climbing, or of course when you're using obvious crutches). What a walking stick _probably_ won't be perceived as is a weapon, so it's also less conspicuous than, say, a scabbard with a sword in it, or... well, nunchaku 😂
@@blahorgaslisk7763 I didn't say "concealability", I did write and indeed mean "inconspicuousness". Of course nunchaku are _also_ somewhat concealable, though there are modern telescoping sticks that are both better concealable as well as longer and... not broken in half. My point was that in the time when they were actually used as weapons by the peasants, nobody perceived them as weapons, so the peasants didn't get into trouble for "carrying around weapons".
@@mcwolf1096 Nunchucks will draw more attention since who do YOU seen walking around with Nunchucks that isn’t seen as a Weeb in modern times?, and I have seen plenty on hiking trips. I thought we were talking about it in the context of the time and not modern day where people will ask what anime you watch if you carry Nunchucks with you. Doesn’t help that people see Nunchucks as weapons more than sticks (Ask the UK and the Hero Turtles)
The whole way you’re trained to hit is to put your body mass behind the blow. When you hit with a stick it’s not just the mass of the stick but some of your weight too. If you’re rotating your whole body into the blow a 3kg stick has tens of kilos behind it.
Man. Came for the Nunchucks jab. Stayed for the physics lesson. I was a trash student in high school. But sticks hitting cantaloupe was exactly what I needed.
I've heard numerous stories of D&D and other fantasy take kids, and adults, who normally have no interest in academics and turn them into someone interested in academics be it physics, history, physiology, etc.
If I understand correctly, the nunchaku was never originally meant to be used as a primary weapon. It is believed to have been an agricultural tool (Eric Bohm has a good comment on why they were great for threshing grain … for the very reasons that make them poor weapons) then later as a training tool for newer students to develop the reflexes and also discipline needed to handle more advanced weapons (since nunchucks are very prone to hitting the wielder if not wielded correctly).
I think for those who says that nunchucks hits harder they really mean for the same mass of sticks, nunchucks have a longer low mass string, assuming the torque at the ends are large enough such that centrifugal force is enough to straighten the nunchucks, for the same angular velocity, the nunchucks will have higher linear velocity. IE: strings are cheap, easy upgrade to make stick longer thus faster, and easier to find then bigger sticks. Edit: also two rods of length L connected by low mass string length k have a higher moment of inertia then a single rod of the same mass and length 2L, parallel axis theorem if I remembered correctly.
Gotta love the fact, even though Shad has clearly stated many times he considers Nunchucks an F tier weapon and not very effective, he STILL technically has them be one of the most extensively covered weapons on his channel.
@@soulsurvivor8293 You've seen his sparring matches and videos of him going against other people??? He beat JAZZA, HIS BROTHER, who is waaaay more physically fit mind you, without a lot of effort at all. With a lot of good technique.
@@soulsurvivor8293 any weapon were you need years of training to be able to utilize it effectively (without hurting yourself in this case) and that training would only let it be on par (at best) with just a sturdy stick, is a bad weapon. Nunchucks look cool, and will continue to be one of the weapons people like to watch being used, but they are not practical in an actual fight, and lose to just a stick.
@@UXMetalVTuber the thing is, jazza was not trained in swordmenship at all. Anyone with a few months worth of basic training will have a high chance beating a completely untrained opponent in a sword duel. Swords ain't some stuff that anyone can just pick up and already be good enough like spear or mace, the thing need training to be utilized effectively. Jazza being fit ain't matter when he's untrained.
Well and also, if there is energy expended to change the direction of the hitting end there is some energy that didn't get expended to permanently deform a human. You only loaded a human spring, you didn't break the human spring. Though somtimes your wooden spring might break instead. Leaving you with a nunchuck.
@@tkathn4301 Considering how you can hit someone and yourself in one go, yes you definetly have an easier time hitting two people. And it's not like a stick is some gigantic unwieldy thing. It's basically only limited by human biomechanics. And needs far less coordination. It's a stick. So easy a child can use it and they do.
@@ayumikuro3768 I recall from when I trained in the escrima stick, I was able to do some pretty rapid fire hits. As you say, the stick is not some unwieldy heavy weapon.
So glad you brought physics to this discussion! I'll even add more clarification regarding the rebound of the weapons following the strike, a very straightforward concept demonstrating why the nunchucks would fall short of a stick with the same mass and swung at the same speed. Again, assuming equal mass and speed, both weapons will carry the same amount of kinetic energy prior to striking. At contact some amount of that energy is imparted to the target, and some back at the weapon. The bounce-back or other movement of the weapon after the strike is (mostly) kinetic energy retained after the strike. It's pretty clear watching the tests that nunchucks have SIGNIFICANTLY more bounce-back as compared to the stick - and therefore more energy retained in the weapon after the hit. Knowing conservation of energy, this must necessarily mean that more energy is being imparted to the target upon impact with the stick. This is likely due to being able to hold onto the entire object and continue following through with the attack, but there's no arguing the physics here. Great video!
Another point, that you mention in the video, but it's actually very important: when you hit "correctly" with a stick, you transfer a part of your body mass into the momentum. That is why when wielding a sword, you try to "turn into" the hit and when striking with a spear, you thrust with your whole body (as opposed to just swinging the sword with one hand or thrusting the speak only using your hands but not moving the body). So we are not only dealing with the mass of the weapon, but the mass of the weapon plus a part of the body mass. For this reason, I think even if you increased the mass of the nunchucks, so that it weighs more than the stick, you will STILL get a "stronger" hit from a stick, provided you know how to strike correctly. Of course, I don't have empirical evidence to show that but I've studied some physics and that's my speculation.
Nunchuck is a girly weapon that is it's sole purpose, it's more effective in the hands of a smaller weaker person than a sword axe practically any other weapon and is more easily carried. Past that it's use as a weapon is nil. Sorry chuck lovers... True fact. if you are arming your subjects then you're not giving chucks to any proper warrior as they're not effective enough at killing enemies. But for a woman who's more interested in the disarm, slowing strikes in order to aid escape! Then it's pretty good when you have no sword arm or skill and you're planning to RUN AWAY!
@@DailyCorvid this is a bit of a weird comment (especially all the stuff about it being a girly weapon) but the reason it's not very effective as a weapon is because it's not intended to be a weapon. Like most stereotypical "ninja weapons", it's a farming tool that was repurposed as a weapon, I'm pretty sure nunchucks specifically are for threshing rice to get the grains off the plant. It doesn't hit hard because that's a horrible thing to have happen when you're trying to just get rice off of a plant. You're not giving them to proper soldiers because it was literally a weapon invented buy peasant farmers who didn't have access to proper weapons. Also, I feel like a short sword or knife would probably still be better for somebody who doesn't have a lot of physical strength. They're not exactly heavy and it doesn't require much skill to cut a bitch from 2 ft away.
Thanks Shad I've long since abandoned thinking nunchucks are good weapons but you still made this video entertaining and polished up my transferring optimal force into the target knowledge.
Simple experience : Cut a baseball bat in two with a chain in the middle... (Be sure that the length stay the same and the weight as close as possible) Compare the power transfer to the ball when you hit it. If the ball fly closer, baseball bat win. If you hit less easily the ball, baseball bat win. If you hurt yourself with the back clash, baseball bat win. If you destroy the ball, you're hulk, stop playing with a baseball bat or a nunchuk please ! Very good video as usual 😄
The risk of self injury is a nonstarter for me. Same for dual weilding same size swords or revolvers. And don't give me the argument "you just have to use it correctly". I want something which I can use in the worst possible situation and still be effective and not self damaging.
For the layman, the baseball example is useful. Imagine hitting a ball with a bat, but you don't keep your wrists firm upon contact. The ball will be hit forward due to the initial velocity of the bat, but it go a much shorter distance compared to a swing with solid form and follow through. Nunchucks are like having limp wrists, except probably a little bit worse. They still function, but you're really gimping yourself out of your potential.
Yeah! There's you next experiment! Cut a baseball bat in half, and attach the two halves with a short piece of rope. Then see how far you can hit a baseball with the nunchuck-bat, vs the regular bat.
The original agricultural implement, a thresher, seems to be the tools of choice for that task because it allows the user to apply enough force to separate the head of the grain from the stalk, while protecting the user from hand shock. The latter element would presumably increase the amount of time the user can spend working, instead of resting.
An interesting deduction! I would add that it could also matter that they are trying to knock the grains loose, rather than destroy the stalk (and possibly grains by crushing them) which would add lots of undesired debris to the grain collection; thus you would intentionally choose something that does less damage with the same effort.
"i think i have that right." momentum is mass times velocity. Impulse is a term that quantifies the overall effect of a force acting over time, or J=F⋅Δt now that isn't the whole story. we have elasticity and compressibility. elasticity determines the rate of transfer both into changing the direction of the object and into the object struck. compressibility helps to determine the rate of transfer. low flexibility and low compressibillity transfers more force into an object rather than letting the projectile/weapon change direction. the flexibility of the whole weapon includes the person swinging it, which means the hand holding the stick tends to be the weak point, reducing the force transferring from the man to the weapon and into the object. this is why you 'snap' your punches, in order to transfer that force into the weapon (in this case your fists) as it hits the object. this is also why 2 hands works better than 1 hand. flexibility does increase the amount of contact time, but it does weaken the force transferred through the flex. that means that you want the nunchucks to bounce to increase the impulse, but force applied over time allows it to transfer through the target so that skin and bones don't have to handle the full amount at once and can spread that force out. that means that transfer of energy for damage should be short and high, thus impulse is not your friend with weapons. good for knocking people back or lifting objects, as it is how you make transfer of force gentler.
By that logic though, wouldn't longer impulse time be ideal? For example you're trying to transfer the pushing force of a strike into something like the human skull, you transfer that pushing force to cause the skull to strike the brain inside of it. On another note, surface level bruises and strikes that transfer force deeper into the body don't seem too comparable here. Either way, a flexible weapon's advantage isn't that it can deliver the same amount of damage as an unbroken kinetic chain of the same length. (I preface this statement with the fact that I have almost no martial arts experience what so ever), but I believe the greatest strength of flexible weapons is the greater burden it places on your opponent to control your weapon, so you are right that a nun-chuck is likely designed to have a shorter impact time,.
@@bungeetoons "By that logic though, wouldn't longer impulse time be ideal?" no. the force put into the skull moves it and then some of that force moves the brain. the strength of the strike of the skull into the brain is the difference in kinetic energy between the two, as the strike is the transfer of energy. if the energy transfer is slow then the difference of energy at any given moment is lower than if the energy transfer was rapid. thus a slow transfer of energy is a weaker strike of the skull into the brain. the distance the skull has to move to reach the brain dictates the 'margin of error' for the rate of transfer. if the time the transfer takes is less than the time it takes the skull to reach the brain the brain must absorb the force instantly (getting it up to speed of the skull) to not be deformed (which is impossible, hence the damage to the brain). same goes for joints in the body or anything else. the energy of the strike does travel through the body, so a low energy high impulse (short time of transfer) strike will cause bruises but not harm the bone underneath as the distance of the surface of the skin to the bone allows the energy to dissipate enough that it doesn't cause issues. if it was low energy and low impulse then the skin itself wouldn't be bruised. if it was high energy low impulse then the person would get shoved rather than get struck. if it is high energy and high impulse then the person has to deal with a shock wave of force traveling through his body. nunchucks are lower energy than a stick, even of comparable length due to the flexible bit. when you carry through your strike with nunchucks the striking stick rotates on the target, which lengthens the time of contact. when you use a whip if you do this it doesn't strike as hard. if you crack a whip right on the target it strikes with much more force, and a similar thing happens with nunchucks (it is much harder to do, and Shad addresses this in his first video on nunchucks as it is impractical and causes bounceback) which allows for much shorter impulse with the same amount of energy transfer.
here's the thing tho with nunchucks, there is only one initial impact before all of the momentum goes another direction, and based on how much the target pushes back the blow, half of the energy might not even go through with some strikes as it naturally gets redirected because of the nature of the weapon with a stick, the force still follows through, you are driving that force in and even if it bounces off (which happens a lot) you are making the force continue into the target also with the "this is why you 'snap' your punches" no, it is said that the idea punching point is when your arm is about extended by 80%, so it has a greater force, but so you can use the other 20% of your reach to make the force of the punch go all the way through. if you "snap" your punches, you are not allowing your punch's force to fully go through so not only is your choice of weapon wack, but your fighting style is a mess too if you still don't get it 15:28 this part explains it best
@@maskofmany9208 I don't think that the concept of the "driving /follow through force" matters all that much. Lets consider the baseball batter following through on the swing, how much would that matter in comparison to not following through? We can actually somewhat estimate that effect by looking at the slow motion video footage. The bat is being swung for about 7 (slowed down) seconds of footage until it impacts the ball, the impact takes two frames. It seems the footage has about 25 frames per second so the impact duration is a fraction of 2/175 of the total duration of the swing. The energy imparted on the bat is the integral of the force that the player puts into it over time, it is reasonable to assume that the force is not going to vary too much over the swing but lets be extremely generous and assume that, at impact, the player somehow manages to have twice the force acting on the bat than the average over the swing so far. This still means that effectively the difference in energy the player but into the system by swinging through is only 4/175 or about 2.2% higher than not swinging through. Also it should be considered that there is a way more reasonable explanations why swinging through is better: It is impossible for a human to estimate the exact time of impact and start decelerating the bat exactly after the impact so players who don't follow through will probably be prone to either deceleration too early or holding back even before the initial impact. If you actually wanted to estimate the difference between not following through and following through you could not use a player for that, you would need a machine that is specifically build so it can immediately let go of the bat upon impact.
I don't think people born in the last 20 years will ever understand Shad's war against nunchucks because they're either too old or too young to get it. But as someone near Shad's age at least, born in that time called the 80's and raised through the 90's you have to understand, when we were young, Ninjas were freaking EVERYWHERE. Particularly the Ninja Turtles were at peak popularity, but it wasn't just them. And as a result, nunchucks were everywhere. And you had tons and tons of nunchuck proponents on the school yard, constantly talking them up, all the time. So I get it. I really do. Hearing about the incredible power of the katana or the nunchucks was just a thing that came along with these fads. And it got annoying. So please Shad, continue your crusade.
I've to tell you Shade, everytime I recieve a notification of any of your videos, is when I'm eating lunch. As I see it, I feel like a medieval monarch in a feast. You basically entertain me as well teach me something new and interesting. Hugs from Portugal and keep up the good work. :)
damn, i WISH i got his notifications during lunch. but it's always while I'm working. and i can't give Shad the proper attention while working so it has to wait until i get home, and i tend to play games when i get home so i load one up out of habit and then I've forgotten about Shad's video until the next morning. It's been over a month since the last time i watched a Shadiversity video same day it was uploaded
I’ve been binge watching a lot of Shad’s videos for the past half month, and only recently did I find out that he had a whole past crusade of nunchuck videos. I thought to myself, “damn, that’s a lot of content, but there can’t be any more to say after all that.” I’m actually glad to be wrong.😁

Imagine your stick breaking mid-impact. That stops the kinetic chain and weakens the overall strike. That's the similar situation with nunchucks -- you can't push the rope, only pull on it.
Yes, but now you have a shorter pointy stick that can deliver force from your body mass, and might be able to be shoved into unpleasant places on the body of the creep you’re beating.
2 ปีที่แล้ว +2
Indeed, and if you connect them with rope, you can't even shove the other one into unpleasant places, since you can't push on the rope, just pull. :D
And if Buffy had sharpened the ends of both of her nunchuck sticks, she could not only beat the crap out of those vampires, but also dusted them from a safer distance with a superior delivery system.
Not a disagreement to your experiment/argument, but at about 12:17 you changing your stance didnt knock the dummy over because you applied more force. It went over because you changed the direction of that force. Although you probably felt like you pushed forward evenly both attempts, your change of wrist orientation(and overall stance) subsequently changed the direction of the force applied to the dummy making rotation towards the ground(falling over) easier. It was unintentional on your part, but that didn't change the force applied in the way you were trying to say it did out loud. If you were to take your first stance and place the tip of the stick on the dummys chin or throat it would be more likely to want to topple over then the tip of the stick being slightly up off the shoulder and pushing like you did. Same with the second stance. If you had tried to push with the stick orientated the second way but with the tip on the dummys chin or throat it would be less likely to topple over than it did when you pushed using the portion of the stick you did while in that same orientation. That changes how the force is applied not necessarily the amount of force applied (by changing orientations in the way you did, alone).
As several others have already pointed out, I don't think adding more mass to the nunchuck is a particularly smart option, nor do I believe it would allow a nunchuck to surpass the basic stick. I've practiced with a Jō staff for around 10 years of my life, and the force you can generate with your own body weight is equivalent to... well... your body weight. If we're not talking usability but only maximum possible force, you'd need to add close to your own body weight to the nunchuck for it to be capable of similarly strong strikes, and I don't think I really need to point out how impossibly hard such a weapon would be to wield given how heavy we've just made it. Try attaching a handle to another human and wielding them like nunchucks, not gonna work.
I actually did that once. 3rd grade. I was the fat nerd who got picked on all the time. Dealing with my regular bullies, I picked up one and clubbed the other one with him. They neglected that the fat kid was a farm boy who was used to hauling hay bales.
It might actually be closer to 10% of the mass of a human due to the higher volocity a weapon should have than your body, but that would still make the nunchucks basically unusable.
@@garethbaus5471 Almost as though it's not true at all. ;) That being said, why do they make famers so weak in RPGs? Like seriously.....pound for pound they're usually the strongest common people you'll ever find. Most adventurers would most likely be farmers if they were a fighting class. Even the romans understood that city folk were usually less effective troops due to their physical inferiority.
When you strike with nunchucks, your arm and entire body keeps moving. When you strike with a stick, your movement stops and the energy is pushed into the target. With a stick you can put your entire body into the blow.
Which brings up an interesting point- inferior weapon that it might be, you can strike with nunchucks without committing your own momentum or center of balance into the attack, almost like how you don't have to commit to an attack with a spear. spear > stick > nunchuck
Hm. The nunchucks' lack of structure due to the tether makes its hitting half move kind of similar to how a thrown half-stick would behave on hit, were it to be thrown with the same speed as the nunchucks' hitting half hits. So the nunchucks are basically a very short range recoverable thrown half-stick with a built-in stick thrower.
"Mom, the Australian man is out in the backyard again." "That's good, honey." "He's talking about physics and kinekic force and lere...lerage and hits a statue with a stick." "Yes he does that."
I do not know if it works with sticks, but with punches you are supposed to use the weight of your whole body (or at least your upper body) instead of your arms strength. You can't transfer the power of your bodys inertia through chain.
Momentum, impulse and velocity are well and good, but you''re missing an important scientific measurement. Levity=Mass + Velocity + Rebound (Striking your own body with the weapon after impact)
This is not me saying nunchucks are better and stuff, but there is a pro of using nunchucks over something like a regular stick. Remember how with regular sticks you drive the force onto the enemy when it hits and with a nunchuck you can't drive the force onto the enemy because of the chain. The opposite can also be said on you. For example, with a regular stick when you hit something hard like a hard wall, you can feel the force also coming back into your hand or in easier words you can feel the pain in your hand when you hit something hard. With nunchucks, you don't feel the force or pain coming back to your hands because of the chain.
Hey Shad, So as a martial artist, I think a lot of hate on nunchucks comes from misunderstanding of the intention behind the weapon. The actual intention behind the weapon as depicted by Bruce Lee and Dan Inosanto is from Kali/Escrima. The standard weapon is a stick/sword but the nunchucks or tabak toyok were created so that the user could carry a concealed weapon. If you think of it, the nunchucks are just a compact stick. Sure the force is reduced but it is made up for by ease of carry and concealability. Filipino escrimadors are masters of stick fighting, but they would carry nunchucks on them in case they got into some altercation. The other use of the nunchuck is actullyban advantage over sticks. They can be used more effectively in grappling and body manipulation. Karate styles emphasize this especially (look up Kudo for reference on some of the techniques). A nunchuck that wraps around an arm can be used to manipulate that limb and grapple the target. You can absolutely do manipulation techniques with a stick but the flexible nature of the nunchuck make it easier in my experience. Lastly, there is a difference between Filipino and Okinawan/Japanese/east asian nunchucks. Filipino nunchucks tend to have longer chains and shorter handles. This is most likely due to them being used for striking and having mass concentrated farther out will maximize the force delivered. Okinawan nunchucks have shorter strings and longer octagonal handles. The shorter strings allow for more pressure in grapples and manipulations while the octagonal handles allow for the hand to be able to control the weapon better during in fighting. You’re absolutely right that the force is lessened by the nunchuck, but they were never made with the intention of increasing force.
Someone... somewhere... is writing a forbidden love story of Shad and Nunchucks having secret meetings behind an old tree in a park, wearing disguises. Don't look at me! I can't write shit to save my life.
Also, History proves which weapon was better. The stick type of weapons could murder faster, smoother, and more gracefully in a match than a nunchuck style weapon ever could. And whats more, you barely need training with stick type weapons! Meanwhile, nunchuck users half the time have to be practically gifted to be able to much of anything, that or train the same amount as a magician
Over all, your arguments are physically sound and you actually explained the key points very well. Rarely you may have put some things in a slightly more confusing than clarifying way and oversimplified a tiny bit, but not in a way as to detract from the entirety. You might have said a few words about the concepts of elastic and inelastic impacts and deformation work, which might have made some explanations a bit more fluid and easier. Great video, and that is coming from someone with a PhD in physics. One of Skallagrim's nunchuks video was taken down right after I commented on it, offering to help him set up the experiments and measure it out once and for all and stating the whole thing is getting a bit annoying, I am embarrassed to say. 😅 I am sure that was just coincidence, but I can't help the suspicion that might have been the video you were talking about.
16:03 Thank you for clarifying! Your previous analogy peeved me a bit (still does a bit, because it's not really like a Jackhammer), but your clarification here hit the nail on the head as to why that situation is actually not ideal and a martial artist would be trying to avoid it occurring, but that this is instead a reason why even a bad strike with a weapon with a static configuration is better on average.
People keep bringing up concealment. You can hide floppy stick better I won't argue that but you don't have to hide a regular stick at all so I fail to see why it matters. On top of that there are better weapons that are far easier to hide than nunchucks. There are better things that are easier to hide that aren't even weapons so you wouldn't really need to hide them anyway. It's this amazing thing called a knife. Like the nunchuck it was not originally a weapon, unlike the nunchuck it's still not a weapon. Yet it's still better at being used as a weapon. Funny how that works.
"you don't have to hide a regular stick" Except if you are talking around with any decent stick, everyone with 2 braincells will consider yourself armed, and will only approach when they consider them amred better than your stick. This applies to walking canes and such as well. Now when you compare nunchocks to weapon with same amount of concealability - you say knife is a better weapon - but last time I checked most of nunchucks gave better striking range than knifes. Sure knifes have their own advantages but it is not so white-and-black as it would seem. Bear in mind I am not saying that nunchucks are any great weapon, I am just saying that they have some advantages over other weapons, that are extremely easy to downplay and handwave away, which is just as unfair as glorify them. (PS. their combat performance to concealability ratio is what got nunchucks illegal in some countries)
@@MehrumesDagon having a cane, crutch or walking stick isn't exactly what most people would consider being armed. Concealment of a weapon isn't done to trick others into attacking you so you can turn the tables it's done because you aren't supposed to have that weapon or in some cases any weapon. There is no need to hide something you are allowed to have. You get frisked before entering a place and nunchucks will get taken away, a cane will not. There are knives plenty long to be comparable to nunchucks and if you want to argue range then a rock thrown or slung will do more than a nunchuck anyway and while people might think you are weird for having rocks in your pocket they aren't likely to take them from you. Nunchuck aren't useless they just aren't good weapons.
@@MehrumesDagon You telling me that the average person looks at a man with a walking stick or cane and considers that person a real threat? You really telling me that? Besides, if you want to conceal a chuck of any decent thickness under some clothes, you'd still need some pretty baggy clothes. And if you're walking around in warm weather with baggy clothes, you're gonna look suspicious. Really, I've tried hiding chucks underneath my gi before. And my gi was pretty thick and baggy. It stood out like a sore thumb. Those were practice chucks that were pretty thin too. I've seen people more successfully conceal large handguns. You will get in trouble if you get caught with a chuck where you're not supposed to have weapons. But a walking stick? Not likely. Stick still wins in overall concealability. Chucks, by their nature of being uncommon, start off with a disadvantage in concealability. In some US states, you'd probably have an easier time explaining why you have a gun in your pants than you would a chuck, especially considering that chucks are a very poor self-defense weapon. So with that in mind, the chucks would need superb concealment in other areas to make up for that starting disadvantage for them to even come close to other common options. And they don't. They're not the hardest thing to conceal, but they're also not the easiest. You'd likely have to stick them in a bag or something, as I already explained how it's actually much harder than most people think it is to conceal something of that thickness underneath common clothing. But a walking stick, you can keep out in the open and is a superior weapon. Plus, in my opinion, walking sticks can look much cooler. And the stick comes in so many more forms, so you might not even need to carry one to have one in easy access. Pipes, tree branches, tool handles, sports equipment, etc. Heck, a hard baguette could work too. The simplicity and commonality of the simple stick is a HUGE advantage for it. It means they're easy to get a hold of, easier to train effectively in, and less likely to draw suspicion. The chuck by comparison has so much to live up to to even be considered against the stick.
@@ermosazorius4279 Actually considering that one of biggest prominence of nunchucks was not-so-recent gangwars over on the other continent, once could say that actually, tricking oponent into attacking you when you are armed and they are not so, could be actuall intend of some people. That also being said, in some neighbourhoods carrying anything resembling a weapon (walking stick included, unless you are elderly) would be a sign provoking an attack in the first place, in which case nunchackus would allow to have a means of abova-average-range of self defence, without actually drawing attention to yourself. as for range - if you want a knife to have same striking range as nunchucks, then you are already having a "knife" that is considerably longer than single "half" of nunchuck which means not so easy to conceal. As for throwing rocks - sure you may be able to toss a rock further than hit with nunchuck, but that won't keep oponent at range, or at least not for long enough for it to matter. as for walking cane not being taken away - over here I am quite sure that unless you are elderly and in factuall need of that cane, football stadium security would take away your walking cane off you if you tried to get in with one. Tho to be completely fair, the stadium security in my city got such improved over last decade that good luck smuggling in any weapon through those guys.... but yeah they are talking walking canes off of people too.
@@ShadeSlayer1911 "You telling me that the average person looks at a man with a walking stick or cane and considers that person a real threat? You really telling me that? " A young person that does not need it for aid in walking? yes. on second paragraph - I have seen people very successfully concealing nunchucks, and just because you were unable to reproduce, does not mean it is impossible. Also if you are having to explain why do you have an item on you, you already failed in concealing it, so I would not take anything requiring that point as "disadvantage in concealment" And true, commonality of the stick means you can not bring a stick and still end up having one, but that is besides the point.
My Word... This is Good stuff. I am student of physics and the Long sword. Your arguments regarding momentum, impuls and Force över time is spot on. I have a small nuget though, a pondering. I am considering the posibillity of conservation of angular momentum. What we are looking for is speed to of set the lower mass and impulse deficiency, so.... Consider a nuncuk strike;, momentum is imparted - Speed is proportional via centripetal acceleration to radius. If you mid strike pull the strike close you will shorten your rotational radius and increase rotational velocity through conservation of momentum. Call it an increase in Speed at the expense of reach. Will it be enough to of set the mighty stick. I don't know.
Newton's 3rd Law: EQUAL and opposite forces. When a ball bounces it puts the SAME force on the ground that the ground puts on it. The ball looses energy to things like heat, sound, and deformation of the ball itself as well as any deformation to the thing it hits.
A great test visually would be to see someone hit a few baseballs with a nunchuck and then with a stick. I bet the baseball hit by nunchuck will not come close to going as far as the baseball hit with the stick. If the nunchuck mechanics were "superior" why would we not use them in place of baseball sticks.. I mean bats? #teamstick
That's bc nunchucks aren't as precise or as strong. They are more of a show off street level (no guns) weapon. They are just.. quick and chaotic. Imo okey enough.
@Z. Michael Gehlke Nun chucks and trampolines are more comparable because they both have give to them. The ground and the stick are both solid, so force imparted by each has a greater effect. The technical physics explanation is circumstance dependent; the point the physics video was making was that a change in momentum is easier to cause with a longer duration. They weren't concerned with whether that change was more or less, only that it happened. The rigidity or kinetic linkage is ultimately a more important factor, which happens to cause the increase of duration.
@Z. Michael Gehlke Simply not true. Seeing how far a ball would fly is a direct result of the force imparted on the ball and how much potential damage you could create to do damage. As Shad said, you're simply operating a much smaller stick with no leverage when using a nunchuck. Take a 1 meter stick and split it in two, you're now down to 50 cm of lethality versus 1 meter. On top of that, you can apply your own body as part of the weapon if there is a solid link. So that 1 meter stick is closer to a 130 cm long weapon that's also slightly heavier depending on the mechanical force you can assert through your pose. The nun chuck has non of this, due to it being disjointed. In fact, if you THREW your stick, it would be comparable to the force you'd achieve with the nun chuck, except the stick will be twice the length and size, so a thrown stick is a much fairer comparison, but it would still win. Thrown stick is ass compared to one used in your hands normally though. The mechanics you impart on the weapon is so much greater for the stick. It really is simple physics. I'm sure someone a lot smarter than me could do the math of the speed the nunchuck would need, to even approach the same amount of kinetic energy a stick would have, to show it would beat a nun chuck, even without the human element in it.
@Z. Michael Gehlke Internal damage is directly proportional to travel distance. Unless the nunchucks can function as scissors that direct force from two opposite direction, how much damage the target takes is directly related to the energy transferred and inertia of the target, and the inertia of a baseball is fixed.
I have a very very hard time believing that Shad uploaded a serious video about nunchucks, which he knows is the most controversial point across his whole channel, on April Fools of all days Fr tho: Love your videos Shad I think they are super super interesting and very entertaining. Also thanks for a better momentum lesson than given by my physics teacher lol
You could do an easy experiment to show how sticks hit "harder" (transfer energy better) than nunchucks: have the stick fixed on one end and able to rotate and basically build a pendulum, putting a ball directly below it. Let it fall from a horizontal position and see how far the ball goes when hit, then do the same with the nunchuck and you will see the ball go a shorter distance.
You can actually see how the nunchucks fail to complete the transferral of energy at around 23:50. I think that they CAN hit *as hard* as a stick- they can produce almost just as much energy, as the statistics examples showed, but like Shad said, thats not the problem- the problem is *transferring* that energy. A battery full of electrical energy is useless if your cable can't transfer that energy fast enough to run the tech it's wired to. Hell, a larger battery may hold more energy, and even be able to *technically* output more as a result- but if the cable it's using to transfer energy can't handle that much, or is too inefficient, the amount and output of that energy is basically rendered useless.
Only way we can solve this... gladatorial arena with two average people that have no combat or martial arts experience whatsoever. Last one standing who is wielding stick or knunchaku will be our answer.
Here's the physics breakdown in some detail: - Momentum is mass times speed. - Impulse is a change in momentum. - A force acting for a certain duration will transfer momentum, and thus is an impulse. - Impulse in this context is basically "amount of damage" - If a higher force is acting for the same duration to transfer momentum, impulse is higher which means more damage - If the same force is acting over a higher duration to transfer momentum, impulse is higher which also means more damage - In the context of nunchucks vs stick, the mass to consider is the mass of the rigid body in motion - For the nunchuck, the relevant rigid body in motion is the part above the linkage - For the stick, the relevant rigid body in motion is the entire stick and some part of the person holding it - The amount of momentum a stick/person has before impact is much higher for the same speed, because of the much higher effective mass for the stick/person rigid body - Momentum is conserved during a collision, which means that the quantity of momentum before impact, the mass times the speed of the weapon's effective rigid body, is equal to the quantity of momentum after impact, the mass times the leftover speed of the weapon plus the mass times the new speed of the target - The highest transfer of momentum would be achieved if the weapon has no speed after impact, hence no momentum, and the target has all of the momentum - Because nunchucks are basically unable to have no speed after impact, which means that some of their momentum is not transferred into the target, and they start out with less momentum in the first place, because of the lower mass of their effective rigid body, there is no way that they could inflict an equivalent transfer of momentum as a stick which starts out with more momentum and may have no speed after impact
Shad, I really like your content and have a question that I'd like to see you cover, if possible. One of my friends mentioned off hand that early Scandinavians during the Viking period unwittingly made crude steel by mixing the ashes of bones of family members or animals in the spiritual belief that it would make their weapons stronger, and the carbon present from the bones would bond with the iron and make a crude alloy. I don't know how true this is, but I think it could be an interesting topic to make a video on!
"[...]If nun-Chucks can hit as hard or harder than a stick of comparable size and weight[...]" - shows a stick that is much beefier than both parts of the nun-chucks in his oher hand combined.
These discussions always remind me of a particular Mythbusters segment that has stuck out in my mind to this day. The segment involved testing a scene from the old Hellboy movie in which Hellboy slams his massive fist into the hood of a car coming at him, causing it to flip clean over him as a result. The test they devised involved dropping a large metal fist onto the hood of a moving car with the necessary momentum to impart the assumed force. While I understand it was likely the most viable test they were able to perform, I was immediately able to see how inaccurate to the original scene it was, and everything was centered around the "tennis match of forces" as you put it. (22:23 vs 22:27)
Yep, the higher velocity of Hellboy's hand would absolutely be necessary for a flip. (The punch still wasn't hard enough to flip a car, but a relatively slow object like the fist the myth busters were using couldn't achieve a similar result no matter how much mass it had.
Training for a spear: pointy end goes in that guy. Training for a sword: pointy end goes in that guy. If not, try slicing. Training for a dagger: stabby stabby Training for a mace: thunk Training for a club: thunk Training for a warhammer: hook and smash Training for nunchucks: hit the guy but keep going or you'll hit yourself. Keep track of the other side of the weapon, or you'll hit yourself. Even then, you'll probably hit yourself because the thing still bounces off a lot. Oh, and you'll need more room to swing, or you can't swing at all. Wait, there's more. What do you mean you'll just stick to the spear?
SPEAR : Thrust forward with own body weight pressed down into small of forward leg. SWORD : Turn into the cut with your forearm and grip strength.

Hey. This was really a non-meme vídeo. No unecessary jokes mixed in the analysis (yes, the Oz comment was necessary), tried to cover all the basis and properly explain the researched topics. Nice Work!
4:10 Just wanted to add to this by bringing up the law of cubes. The larger the object, the more volume and mass it has, but doubling an objects size does more than double the volume and mass. You can see this in action by dropping a mouse, a human, and a horse from a two store building (don't actually do this.) The mouse will be winded, but fine because it's mass is small enough that the force it absorbs is minimal. The human will also be fine, but may have a broken bone. The horse... well that's a pile of meat and bones. Btw the general force equation is Force= mass * acceleration. The different factors are added into each part depending on where they apply (like the constant pull of gravity.) The acceleration of gravity is 9.8 m/s/s, so in the mouse, human, horse example you can see why the force changes so much. As for the stick vs nunchucks debate, the main driving difference between the two is the mass. Having the ability to use the stick with torque is also a huge boon for the stick. More or less, the longer an object, the more torque (or rather the rotational force) it can apply. That kinetic chain is important.
There's a reasonable chance of death for a human falling 2 stories, and high likelihood of multiple complex fractures. Squirrel might be a better choice as they can survive their terminal velocity i believe.
your kidna close, but kinda not with your force equation. that equation is used to determine the netforce being applied to an object that is accelerating at a given rate (or determine how quickly an object will accelerate if a constant given force is applied to it. in either case, the maginitude of acceleration due to gravity is largely irrelevant to how how much harm would befall your falling animals. what *is* relevant is the velocity they're able to achieve, and their individual masses (i.e. momentum) as well as how long it takes them to reach 0 velocity. *thats* the acceleration that matters. how quickly they go from falling to being flat on the ground. not how quickly they were accelerating while in the air.
I think we can clearly put to bed that nunchuks cannot and will never be able to transfer as much force into a target as a stick of equivalent length/size. The follow-up questions I'd love to see tested is what is the actual energy required to get nunchucks moving to the velocity at which you start seeing diminishing returns, and then how much force you can deal with a stick, using that same amount of energy? Is it easier to maintain use of nunchucks at it's peak force output for longer, compared to a stick?
Would love to see testing on ballistic gel dummies. Of course, the zombie version, so there's less chance of getting demonitised. (The Elder Gods of TH-cam: "Green blood is okay," as shown by Demolition Ranch and Kentucky Ballistics, recently. 😁)
It would be really interessting to compare multiple different sticks to nunchucks, 1) with the same weapon reach and stick diameter of the Nunchuck, like shad is doing it here 2) (probably unnessasary) Same Weight and diameter , so a little shorter because the string gives reach with very little mass. 3 ) same backing/ equal cariing dimensions as a folded Nunchuck, same mass as complete nunchuk but only length of one nunchuk "arm" 4 ) half nunchuk, to fairly explore shads idea "rip it appart an use it as two short sticks"
There are a couple of things though.. 1) Would you always look for the strongest hit? From what I can tell, every one of those stick hits demonstrated would be deadly. If a burglar attacked me at home I would use a stick (there happens to be one nearby, for lowering the ceiling trapdoor), but I would not use deadly force. It's terribly painful with way less than full force. 2) The nunchuck *can* "reach around" something which the other person is trying to defend himself, the stick can't. 3) With nunchucks you avoid hand shocks, which *may* be good.. obviously there's less force, but ref. 1). 4) Obviously there's the huge risk of hitting yourself with that nunchuck, particularly if the other person does something you can't or didn't expect, and 5) You can't use the nunchuck to poke someone, which is one of the strategies I might want to utilize on that imagined burglar.
Indeed you can "hit around" a shield. But the force would be even less because the chain between the nunchuck is deformed! It can still deal some damage but may not be sufficient to incapacitate anyone, what then? By the time you recover a nunchuck to spin it again, you may be in trouble! Hitting around a shield can only intimidate an inexperienced person. A flail would do a better job at this because of its spiky end which could minimize the area of impact and, therefore, deliver more force into a smaller area. Poking falls into the category of "versatility". Nunchuck is just so bad at versatility, which has been pointed out before.
The nunchuck falls in that category of weapons of convenience. In Eastern Asia there have been generally more bans on owning of proper weapons either by law or cultural norm. Back then no one expected to get attack by a guy using a grain flail. It has no merit other than sometimes being the weapon closest to hand (which is often the weapon best for self-defense).
Counter point, a walking stick is much more convenient than a pair of handicapped sticks with a strong emotional connection that you keep in your bag or belt.
And in the chuck norris movie the guru smacked the bad guy with a (old-fashioned desk model) telephone. And said pretty much the same thing. Use what you have.
@@glasletter3111 Holly cow are we getting a little pedantic? A ninja might also use one because farmers are a common disguise and farmers use grain flails.
I think there is more to be said on the elasticity/hardness of the target in relation to the impact. For example, when swinging a stick against a concrete floor there is no advantage to holding it against the floor. No matter what there is rebound energy and it just depends whether that is potential energy of the stick bouncing up or vibration in your hands (or nunchuck hitting you in the face), either way its there. In a composite structure like the test dummy it can only deform so far before it becomes essentially a rigid structure. By following through you are adding additional force throughout the contact time allowing you to more easily overcome the elastic potential of the outer foam and have as much force as possible transferred to the rigid core. Either way stick does better due to more mass plus the mass of the person and the ability to follow through but contact time isn't exactly how you are portraying it.
Yes, he's got the concept of momentum a little backwards. You don't get more momentum transfer in an impact because you increased the contact time. The contact time increases because the material deforms when placed under higher stress, and that deformation increases the time it takes for the collision to complete. If you had perfectly rigid objects colliding the impact would be instantaneous no matter how much momentum was involved. But real life is squishy.
2:15 you make a big physics mistake!!!!! What is transferred from the stick is energy. Kinetic energy to be specific. But energy isn't transferred to the stick it's sapped from it. What the stick feels is the same force he applies. As per newton's third law of motion: action and reaction. So when the stick hits the head, it stops moving as fast because the energy was passed to the head that was hit.
Been rewatching Dardevil for the fourth time and the way they depict his sticks in the show is really cool in my opinion. It can go from being a billy club, to nunchucks, to a ranged projectile when thrown. Not to mention the cord that can be used as a grapple hook or to choke someone out. I know it's not "relevant" in the algorithm right now, but there's a lot of attention to detail in that show and all the Marvel Netflix shows that put the modern shows to shame. I'd be curious to see your coverage on them, or at least Daredevil. If not on this channel, maybe on Knight's Watch? A guy can dream. It's more refreshing than ever in this day and age where Disney is creatively bankrupt and the shows have such waning quality.
So Shad, today I got into my first actual sword fight. Let me just say, if I went into another one but without the sword I most certainly would rather use my fists over Nunchucks. Why? Cause they take too much frelling training to use and not hurt yourself.
I been using sticks, swords, chain spears and chuks for my whole life. Dont be mislead by this video. Im sure a katana does no more damage than a butchers knife in these test standards. A perfected whip with chucks takes firstly crafting the chuku measurements precisely to the dimensions of your body. Then adding weight to the ends of the chuku gradually while training until your bodies muscles and weight balance have adapted to the motion. Eventually using heavy metals will have the entire weight of that stick in the tip of a chuk. Then they crack like a lead whip and sound like a gun shot when they hit....but theres more chance of surviving a gunshot. PLUS... you can climb, jump and conceal them through any security. Try that with your precious swords looking like a dickhead. You can also throw'm away and make another pair in under an hour for less than $10. And they are useless in the hands of others. Compared to all other weapons. CHUKS WIN. FATALITY
An important part of the equation for the stick vs nunchuk which automatically makes the nunchuck worse is that when you swing the club you aren't just adding the sticks momentum. You are also adding your arm and a decent portion of your bodyweight into the swing.
You can even see at around 23:50 that when he hits the boards with the nunchucks, the board bounces BACK UP, because that 'tennis match- of forces wasn't allowed to be completed, and left energy in the board for it to 'hit the tennis ball' so to speak. Whereas with the stick, you can clearly see how the follow through absolutely DESTROYS the board- the deformation is so severe the wood noticably shatters and splinters.
Probably the best example to show all the principles you've mentioned in a clearly visibly way (as opposed to a very heavy, stationary humanoid target), and show just how inefficient the nunchucks are at transferring energy. The cantaloupe in the next example also does the same, albeit to a much lesser extent likely due it's weight.
The follow through allowed the stick to overcome the springiness of the cantaloupe and actually deform it, little by little over the duration of the strike, until it was completely smashed, unlike the nunchucks. You can even see he tried to follow through on the strike with both the nunchucks and the stick, so that isn't the problem.

Self harm is a problem when practicing with them in your bed room, or that's what I told my mum ......... 😂😁
Be glad you were not hit with a stick then.
Good thing you didn't compare it to a stick then,
Thanks for the mention, Shad. Your point about two-handed wielding and potential leverage advantage/kinetic linkage/enhanced control of the flute/stick is well worth investigating, so the Wushu Scientist and I accept your research proposal. We will repeat the tests using two-handed striking techniques and see what kind of results we get.
What I wonder about is using less than maximum force. For a stick, the force you put in and the force you get out is fairly linear (I'm assuming; could be wrong). However, is the same true for a nunchuck? It feels like you can get a faster acceleration for lower input force, at least up to a certain level, and I wonder how much effect that has on the strike force. Would that potentially generate enough force to be an effective weapon, or would it still be too little?
Awesome, can't wait to see your results!
I'm really interested to see how much more force proper technique can give.
Stick science
Yes that's what we need. Actual science, testing, numbers. My instincts say shad is right but we all know our instincts are dumb (at least we should) and you should never trust them which is why we do science. Reading up on what parts of an impact do damage would also be good. In crash testing you often talk about jerk as well so that might be an avenue of investigation.
Actually, for the stick, you get to add in the mass of your whole arm and some of the rest of your body too depending on how you swing it. Even with one a handed swing.

@@OurHereafter Yeap, that's how it works.
Before we know it, he'll publish a peer-reviewed paper about nunchucks.
Your mention of the targets being springy has given me an idea on how to improve nunchucks. What if we removed one stick from the stick and string, made the stick which is still attached to the string more _springy_ and then connected the string to the top and bottom of the stick to make an arch. Then we sharpen the detached stick, place it on the string, pull back the string to make the now springy other half of the nunchuck bend, then we release the string and sharpened stick, and it will be launched forwards at high speeds!
We have now created a superior ranged version of nunchucks, created using very similar materials of 2 sticks and a bit of string. You're welcome. It's suspiciously similar to my improved version of the throwing knife, but I'm sure that's just coincidence.

@Part-Time Gamer where the did you get that from? Of course the nunchucks could severely harm? No one has ever said they could not. The reason that weapon gets a fair bit of hate is because it is one of, if not the weakest weapon. Even a regular stick of same size/dimensions is more dangerous, and easier to use for that matter. It is still a weapon that can severely damage or kill, of course. But compared to pretty much all other weapons, it’s an awful weapon.
@@RWAsur

@@fugumeister7563 yeah, I would rather fight with my bare hands than the stupid string sticks
Ive practiced nunchucks casually for about 8 years.
Pros
-great dexterity/hand eye coordination trainer
-forearm workout
-its an exotic weapon that's rarely used. Many won't know its true weaknesses unless they've studied.
Flaws
-blocking with this weapon is not advised, dodging required.
-danger to yourself.
-unless it hits at full length and follows through, this weapon bounces and loses control easily.
-cheap pairs are unreliable and break easy.
-practice required outweighs actually combat effectiveness.
-the weapon is utterly useless against anything lengthy or heavy.
In the end they're great weapons to practice and condition your body for superior, more reliable weapons. You can only use them in combat if you have a reliable pair that lasts, if you're trained in many different strikes/transitions and if you literally have nothing else in reach.
When this whole thing started I was taking a dynamics class so I worked it out from that perspective.
Because there was so much debate as to how much force was transferred, I just assumed perfect transfer for both, and even then the result was pretty conclusive-
A nunchuck with the same mass would have to move not just moderately faster, but **much** faster (>2x iirc) to make delivery of the same energy even theoretically possible.

I'd say the _one_ advantage of nunchaku is the inconspicuousness - _that they had when they were first used as weapons instead of farming tools._ It's like the walking cane effect (or umbrella would be an even better example nowadays since walking sticks are pretty unusual in most 'environments') - nobody sees it as a weapon since nobody _uses_ it as a weapon, and it has a completely different usage that everyone employs, so everyone sees "anti-rain tool" instead of "thin stick sturdy enough for one or two fairly hard strikes".
Was looking for this comment. In addition it should be remembered that they were flails used for threshing. That is repeatedly whacking rice, wheat and so on to separate the edible part of the grain from the straw and chaff. You can do this with a stick, but by using a flail less of the energy is fed back into your hand and arm. So that flexible joint isn't there to increase power but to make it easier on the user.
If all you use it for is hitting people it's not the optimal weapon by far, and a stick is going to do more damage. Some mean the joint makes it a more flexible weapon. Well yea, but even so it's not really that impressive. What it does better than a stick is conceal a four foot long stick. Nunchucks are a lot shorten when folded up.
All in all I'd say there are situations when they can be a better choice than a stout stick, but usually that's because you can't have a stout stick...
If all you care about is efficiency, protection and damage the stick will win.

Walking sticks _will_ draw attention (except in pretty specific situations such as mountain climbing, or of course when you're using obvious crutches).

The whole way you’re trained to hit is to put your body mass behind the blow. When you hit with a stick it’s not just the mass of the stick but some of your weight too. If you’re rotating your whole body into the blow a 3kg stick has tens of kilos behind it.

Defend your virginity with nunchuks!
Man. Came for the Nunchucks jab. Stayed for the physics lesson. I was a trash student in high school. But sticks hitting cantaloupe was exactly what I needed.
I've heard numerous stories of D&D and other fantasy take kids, and adults, who normally have no interest in academics and turn them into someone interested in academics be it physics, history, physiology, etc.
If I understand correctly, the nunchaku was never originally meant to be used as a primary weapon. It is believed to have been an agricultural tool (Eric Bohm has a good comment on why they were great for threshing grain … for the very reasons that make them poor weapons) then later as a training tool for newer students to develop the reflexes and also discipline needed to handle more advanced weapons (since nunchucks are very prone to hitting the wielder if not wielded correctly).
Get hit in the head by nunchucks
And see how much more you respect them
I think for those who says that nunchucks hits harder they really mean for the same mass of sticks, nunchucks have a longer low mass string, assuming the torque at the ends are large enough such that centrifugal force is enough to straighten the nunchucks, for the same angular velocity, the nunchucks will have higher linear velocity. IE: strings are cheap, easy upgrade to make stick longer thus faster, and easier to find then bigger sticks.
Edit: also two rods of length L connected by low mass string length k have a higher moment of inertia then a single rod of the same mass and length 2L, parallel axis theorem if I remembered correctly.
Gotta love the fact, even though Shad has clearly stated many times he considers Nunchucks an F tier weapon and not very effective, he STILL technically has them be one of the most extensively covered weapons on his channel.

I will have nun of this, Chuck all the arguments out the window
So glad you brought physics to this discussion! I'll even add more clarification regarding the rebound of the weapons following the strike, a very straightforward concept demonstrating why the nunchucks would fall short of a stick with the same mass and swung at the same speed.
Again, assuming equal mass and speed, both weapons will carry the same amount of kinetic energy prior to striking. At contact some amount of that energy is imparted to the target, and some back at the weapon. The bounce-back or other movement of the weapon after the strike is (mostly) kinetic energy retained after the strike. It's pretty clear watching the tests that nunchucks have SIGNIFICANTLY more bounce-back as compared to the stick - and therefore more energy retained in the weapon after the hit. Knowing conservation of energy, this must necessarily mean that more energy is being imparted to the target upon impact with the stick. This is likely due to being able to hold onto the entire object and continue following through with the attack, but there's no arguing the physics here.

Nunchuku versus Flails

I cannot for the life of me pay attention in my physics lectures, but this holds my attention
Shad, please be my physics professor
and to explain how physics work, he will rant on how shit nunchucks are and why! =P
Another point, that you mention in the video, but it's actually very important: when you hit "correctly" with a stick, you transfer a part of your body mass into the momentum. That is why when wielding a sword, you try to "turn into" the hit and when striking with a spear, you thrust with your whole body (as opposed to just swinging the sword with one hand or thrusting the speak only using your hands but not moving the body).
So we are not only dealing with the mass of the weapon, but the mass of the weapon plus a part of the body mass. For this reason, I think even if you increased the mass of the nunchucks, so that it weighs more than the stick, you will STILL get a "stronger" hit from a stick, provided you know how to strike correctly.
Of course, I don't have empirical evidence to show that but I've studied some physics and that's my speculation.
Nunchuck is a girly weapon that is it's sole purpose, it's more effective in the hands of a smaller weaker person than a sword axe practically any other weapon and is more easily carried. Past that it's use as a weapon is nil.
Sorry chuck lovers... True fact. if you are arming your subjects then you're not giving chucks to any proper warrior as they're not effective enough at killing enemies. But for a woman who's more interested in the disarm, slowing strikes in order to aid escape! Then it's pretty good when you have no sword arm or skill and you're planning to RUN AWAY!
You don't need evidence bruh this should be obvious to anyone that ever grabed a stick
A weighted nunchaku is colled a combat flail...
Its a bit longer btw.
@@DailyCorvid this is a bit of a weird comment (especially all the stuff about it being a girly weapon) but the reason it's not very effective as a weapon is because it's not intended to be a weapon.
Like most stereotypical "ninja weapons", it's a farming tool that was repurposed as a weapon, I'm pretty sure nunchucks specifically are for threshing rice to get the grains off the plant. It doesn't hit hard because that's a horrible thing to have happen when you're trying to just get rice off of a plant. You're not giving them to proper soldiers because it was literally a weapon invented buy peasant farmers who didn't have access to proper weapons.
Also, I feel like a short sword or knife would probably still be better for somebody who doesn't have a lot of physical strength. They're not exactly heavy and it doesn't require much skill to cut a bitch from 2 ft away.

The risk of self injury is a nonstarter for me. Same for dual weilding same size swords or revolvers. And don't give me the argument "you just have to use it correctly". I want something which I can use in the worst possible situation and still be effective and not self damaging.
For the layman, the baseball example is useful. Imagine hitting a ball with a bat, but you don't keep your wrists firm upon contact. The ball will be hit forward due to the initial velocity of the bat, but it go a much shorter distance compared to a swing with solid form and follow through. Nunchucks are like having limp wrists, except probably a little bit worse. They still function, but you're really gimping yourself out of your potential.
Yeah, if nunchucks could hit harder, someone would have probably tried hitting baseballs with nunchucks and get a comparable distance,
The flexible element is very inefficient.
Yeah! There's you next experiment! Cut a baseball bat in half, and attach the two halves with a short piece of rope. Then see how far you can hit a baseball with the nunchuck-bat, vs the regular bat.
in civilised countries we play cricket
@@archiebf4524 In more civilised countries we play pesäpallo.
The original agricultural implement, a thresher, seems to be the tools of choice for that task because it allows the user to apply enough force to separate the head of the grain from the stalk, while protecting the user from hand shock. The latter element would presumably increase the amount of time the user can spend working, instead of resting.
An interesting deduction! I would add that it could also matter that they are trying to knock the grains loose, rather than destroy the stalk (and possibly grains by crushing them) which would add lots of undesired debris to the grain collection; thus you would intentionally choose something that does less damage with the same effort.
Reducing hand shock is likely a reason why flails were used on horse back.
Can't believe this is still going on, i thought the last couple video is enough information, and i actually still learning something new again
"i think i have that right."
momentum is mass times velocity.
Impulse is a term that quantifies the overall effect of a force acting over time, or J=F⋅Δt
now that isn't the whole story. we have elasticity and compressibility. elasticity determines the rate of transfer both into changing the direction of the object and into the object struck. compressibility helps to determine the rate of transfer. low flexibility and low compressibillity transfers more force into an object rather than letting the projectile/weapon change direction. the flexibility of the whole weapon includes the person swinging it, which means the hand holding the stick tends to be the weak point, reducing the force transferring from the man to the weapon and into the object. this is why you 'snap' your punches, in order to transfer that force into the weapon (in this case your fists) as it hits the object. this is also why 2 hands works better than 1 hand. flexibility does increase the amount of contact time, but it does weaken the force transferred through the flex. that means that you want the nunchucks to bounce to increase the impulse, but force applied over time allows it to transfer through the target so that skin and bones don't have to handle the full amount at once and can spread that force out. that means that transfer of energy for damage should be short and high, thus impulse is not your friend with weapons. good for knocking people back or lifting objects, as it is how you make transfer of force gentler.
By that logic though, wouldn't longer impulse time be ideal? For example you're trying to transfer the pushing force of a strike into something like the human skull, you transfer that pushing force to cause the skull to strike the brain inside of it. On another note, surface level bruises and strikes that transfer force deeper into the body don't seem too comparable here. Either way, a flexible weapon's advantage isn't that it can deliver the same amount of damage as an unbroken kinetic chain of the same length. (I preface this statement with the fact that I have almost no martial arts experience what so ever), but I believe the greatest strength of flexible weapons is the greater burden it places on your opponent to control your weapon, so you are right that a nun-chuck is likely designed to have a shorter impact time,.
@@bungeetoons "By that logic though, wouldn't longer impulse time be ideal?" no. the force put into the skull moves it and then some of that force moves the brain. the strength of the strike of the skull into the brain is the difference in kinetic energy between the two, as the strike is the transfer of energy. if the energy transfer is slow then the difference of energy at any given moment is lower than if the energy transfer was rapid. thus a slow transfer of energy is a weaker strike of the skull into the brain. the distance the skull has to move to reach the brain dictates the 'margin of error' for the rate of transfer. if the time the transfer takes is less than the time it takes the skull to reach the brain the brain must absorb the force instantly (getting it up to speed of the skull) to not be deformed (which is impossible, hence the damage to the brain). same goes for joints in the body or anything else. the energy of the strike does travel through the body, so a low energy high impulse (short time of transfer) strike will cause bruises but not harm the bone underneath as the distance of the surface of the skin to the bone allows the energy to dissipate enough that it doesn't cause issues. if it was low energy and low impulse then the skin itself wouldn't be bruised. if it was high energy low impulse then the person would get shoved rather than get struck. if it is high energy and high impulse then the person has to deal with a shock wave of force traveling through his body.
nunchucks are lower energy than a stick, even of comparable length due to the flexible bit. when you carry through your strike with nunchucks the striking stick rotates on the target, which lengthens the time of contact. when you use a whip if you do this it doesn't strike as hard. if you crack a whip right on the target it strikes with much more force, and a similar thing happens with nunchucks (it is much harder to do, and Shad addresses this in his first video on nunchucks as it is impractical and causes bounceback) which allows for much shorter impulse with the same amount of energy transfer.
here's the thing tho
with nunchucks, there is only one initial impact before all of the momentum goes another direction, and based on how much the target pushes back the blow, half of the energy might not even go through with some strikes as it naturally gets redirected because of the nature of the weapon
with a stick, the force still follows through, you are driving that force in and even if it bounces off (which happens a lot) you are making the force continue into the target
also with the "this is why you 'snap' your punches" no, it is said that the idea punching point is when your arm is about extended by 80%, so it has a greater force, but so you can use the other 20% of your reach to make the force of the punch go all the way through. if you "snap" your punches, you are not allowing your punch's force to fully go through
so not only is your choice of weapon wack, but your fighting style is a mess too
if you still don't get it 15:28 this part explains it best
@@maskofmany9208 I don't think that the concept of the "driving /follow through force" matters all that much.
Lets consider the baseball batter following through on the swing, how much would that matter in comparison to not following through?
We can actually somewhat estimate that effect by looking at the slow motion video footage.
The bat is being swung for about 7 (slowed down) seconds of footage until it impacts the ball, the impact takes two frames.
It seems the footage has about 25 frames per second so the impact duration is a fraction of 2/175 of the total duration of the swing.
The energy imparted on the bat is the integral of the force that the player puts into it over time, it is reasonable to assume that the force is not going to vary too much over the swing but lets be extremely generous and assume that, at impact, the player somehow manages to have twice the force acting on the bat than the average over the swing so far. This still means that effectively the difference in energy the player but into the system by swinging through is only 4/175 or about 2.2% higher than not swinging through.
Also it should be considered that there is a way more reasonable explanations why swinging through is better:
It is impossible for a human to estimate the exact time of impact and start decelerating the bat exactly after the impact so players who don't follow through will probably be prone to either deceleration too early or holding back even before the initial impact.
If you actually wanted to estimate the difference between not following through and following through you could not use a player for that, you would need a machine that is specifically build so it can immediately let go of the bat upon impact.
Nerds
I don't think people born in the last 20 years will ever understand Shad's war against nunchucks because they're either too old or too young to get it. But as someone near Shad's age at least, born in that time called the 80's and raised through the 90's you have to understand, when we were young, Ninjas were freaking EVERYWHERE. Particularly the Ninja Turtles were at peak popularity, but it wasn't just them. And as a result, nunchucks were everywhere. And you had tons and tons of nunchuck proponents on the school yard, constantly talking them up, all the time.
So I get it. I really do. Hearing about the incredible power of the katana or the nunchucks was just a thing that came along with these fads. And it got annoying. So please Shad, continue your crusade.

It's been over a month since the last time i watched a Shadiversity video same day it was uploaded
I’ve been binge watching a lot of Shad’s videos for the past half month, and only recently did I find out that he had a whole past crusade of nunchuck videos. I thought to myself, “damn, that’s a lot of content, but there can’t be any more to say after all that.”
I’m actually glad to be wrong.😁
Imagine your stick breaking mid-impact. That stops the kinetic chain and weakens the overall strike. That's the similar situation with nunchucks -- you can't push the rope, only pull on it.
Yes, but now you have a shorter pointy stick that can deliver force from your body mass, and might be able to be shoved into unpleasant places on the body of the creep you’re beating.
Indeed, and if you connect them with rope, you can't even shove the other one into unpleasant places, since you can't push on the rope, just pull. :D
And if Buffy had sharpened the ends of both of her nunchuck sticks, she could not only beat the crap out of those vampires, but also dusted them from a safer distance with a superior delivery system.
Not a disagreement to your experiment/argument, but at about 12:17 you changing your stance didnt knock the dummy over because you applied more force. It went over because you changed the direction of that force.
Although you probably felt like you pushed forward evenly both attempts, your change of wrist orientation(and overall stance) subsequently changed the direction of the force applied to the dummy making rotation towards the ground(falling over) easier. It was unintentional on your part, but that didn't change the force applied in the way you were trying to say it did out loud.
If you were to take your first stance and place the tip of the stick on the dummys chin or throat it would be more likely to want to topple over then the tip of the stick being slightly up off the shoulder and pushing like you did. Same with the second stance. If you had tried to push with the stick orientated the second way but with the tip on the dummys chin or throat it would be less likely to topple over than it did when you pushed using the portion of the stick you did while in that same orientation. That changes how the force is applied not necessarily the amount of force applied (by changing orientations in the way you did, alone).

As several others have already pointed out, I don't think adding more mass to the nunchuck is a particularly smart option, nor do I believe it would allow a nunchuck to surpass the basic stick. I've practiced with a Jō staff for around 10 years of my life, and the force you can generate with your own body weight is equivalent to... well... your body weight. If we're not talking usability but only maximum possible force, you'd need to add close to your own body weight to the nunchuck for it to be capable of similarly strong strikes, and I don't think I really need to point out how impossibly hard such a weapon would be to wield given how heavy we've just made it. Try attaching a handle to another human and wielding them like nunchucks, not gonna work.
Plus, a stick with a person on it would still be better than a string with a person on it. Stick wins again
I actually did that once. 3rd grade. I was the fat nerd who got picked on all the time. Dealing with my regular bullies, I picked up one and clubbed the other one with him. They neglected that the fat kid was a farm boy who was used to hauling hay bales.
It might actually be closer to 10% of the mass of a human due to the higher volocity a weapon should have than your body, but that would still make the nunchucks basically unusable.
@@lukediehl1210 moving bales in 3rd grade is fairly impressive.
@@garethbaus5471 Almost as though it's not true at all. ;) That being said, why do they make famers so weak in RPGs? Like seriously.....pound for pound they're usually the strongest common people you'll ever find. Most adventurers would most likely be farmers if they were a fighting class. Even the romans understood that city folk were usually less effective troops due to their physical inferiority.
When you strike with nunchucks, your arm and entire body keeps moving. When you strike with a stick, your movement stops and the energy is pushed into the target. With a stick you can put your entire body into the blow.
Which brings up an interesting point- inferior weapon that it might be, you can strike with nunchucks without committing your own momentum or center of balance into the attack, almost like how you don't have to commit to an attack with a spear.
spear > stick > nunchuck
Always enjoy a good physics class. :D
Hm. The nunchucks' lack of structure due to the tether makes its hitting half move kind of similar to how a thrown half-stick would behave on hit, were it to be thrown with the same speed as the nunchucks' hitting half hits.
So the nunchucks are basically a very short range recoverable thrown half-stick with a built-in stick thrower.

Shad and nunchucks? This is going to be a treat.
I do not know if it works with sticks, but with punches you are supposed to use the weight of your whole body (or at least your upper body) instead of your arms strength. You can't transfer the power of your bodys inertia through chain.
Funny, I was just reminiscing on the video that kicked this off with my little brother yesterday, then got a continuation this morning. Thanks Shad!
Momentum, impulse and velocity are well and good, but you''re missing an important scientific measurement.
Levity=Mass + Velocity + Rebound (Striking your own body with the weapon after impact)
This is not me saying nunchucks are better and stuff, but there is a pro of using nunchucks over something like a regular stick. Remember how with regular sticks you drive the force onto the enemy when it hits and with a nunchuck you can't drive the force onto the enemy because of the chain.
The opposite can also be said on you. For example, with a regular stick when you hit something hard like a hard wall, you can feel the force also coming back into your hand or in easier words you can feel the pain in your hand when you hit something hard. With nunchucks, you don't feel the force or pain coming back to your hands because of the chain.
Hey Shad,
So as a martial artist, I think a lot of hate on nunchucks comes from misunderstanding of the intention behind the weapon. The actual intention behind the weapon as depicted by Bruce Lee and Dan Inosanto is from Kali/Escrima. The standard weapon is a stick/sword but the nunchucks or tabak toyok were created so that the user could carry a concealed weapon. If you think of it, the nunchucks are just a compact stick. Sure the force is reduced but it is made up for by ease of carry and concealability. Filipino escrimadors are masters of stick fighting, but they would carry nunchucks on them in case they got into some altercation.
The other use of the nunchuck is actullyban advantage over sticks. They can be used more effectively in grappling and body manipulation. Karate styles emphasize this especially (look up Kudo for reference on some of the techniques). A nunchuck that wraps around an arm can be used to manipulate that limb and grapple the target. You can absolutely do manipulation techniques with a stick but the flexible nature of the nunchuck make it easier in my experience.
Lastly, there is a difference between Filipino and Okinawan/Japanese/east asian nunchucks. Filipino nunchucks tend to have longer chains and shorter handles. This is most likely due to them being used for striking and having mass concentrated farther out will maximize the force delivered. Okinawan nunchucks have shorter strings and longer octagonal handles. The shorter strings allow for more pressure in grapples and manipulations while the octagonal handles allow for the hand to be able to control the weapon better during in fighting.
You’re absolutely right that the force is lessened by the nunchuck, but they were never made with the intention of increasing force.

Don't think about it!
Trust me... do _not_ think about it.
Also, History proves which weapon was better. The stick type of weapons could murder faster, smoother, and more gracefully in a match than a nunchuck style weapon ever could. And whats more, you barely need training with stick type weapons! Meanwhile, nunchuck users half the time have to be practically gifted to be able to much of anything, that or train the same amount as a magician
With a stick you're focusing on hiting. With nunchucs you have to divert some of your focus to dodging your own weapon...
,,I am deforming the ball with the Force"
Shad is a Jedi master, confirmed.
Over all, your arguments are physically sound and you actually explained the key points very well. Rarely you may have put some things in a slightly more confusing than clarifying way and oversimplified a tiny bit, but not in a way as to detract from the entirety. You might have said a few words about the concepts of elastic and inelastic impacts and deformation work, which might have made some explanations a bit more fluid and easier. Great video, and that is coming from someone with a PhD in physics. One of Skallagrim's nunchuks video was taken down right after I commented on it, offering to help him set up the experiments and measure it out once and for all and stating the whole thing is getting a bit annoying, I am embarrassed to say. 😅 I am sure that was just coincidence, but I can't help the suspicion that might have been the video you were talking about.
I love how Shad is willing to learn so much to know the truth, and then present that to us and teach us in turn ♥
Science beats nunchucks!
Science doesn’t matter when you are hit in the head lol
16:03
Thank you for clarifying! Your previous analogy peeved me a bit (still does a bit, because it's not really like a Jackhammer), but your clarification here hit the nail on the head as to why that situation is actually not ideal and a martial artist would be trying to avoid it occurring, but that this is instead a reason why even a bad strike with a weapon with a static configuration is better on average.
People keep bringing up concealment. You can hide floppy stick better I won't argue that but you don't have to hide a regular stick at all so I fail to see why it matters. On top of that there are better weapons that are far easier to hide than nunchucks. There are better things that are easier to hide that aren't even weapons so you wouldn't really need to hide them anyway. It's this amazing thing called a knife. Like the nunchuck it was not originally a weapon, unlike the nunchuck it's still not a weapon. Yet it's still better at being used as a weapon. Funny how that works.
"you don't have to hide a regular stick"
Except if you are talking around with any decent stick, everyone with 2 braincells will consider yourself armed, and will only approach when they consider them amred better than your stick. This applies to walking canes and such as well.
Now when you compare nunchocks to weapon with same amount of concealability - you say knife is a better weapon - but last time I checked most of nunchucks gave better striking range than knifes. Sure knifes have their own advantages but it is not so white-and-black as it would seem.
Bear in mind I am not saying that nunchucks are any great weapon, I am just saying that they have some advantages over other weapons, that are extremely easy to downplay and handwave away, which is just as unfair as glorify them.
(PS. their combat performance to concealability ratio is what got nunchucks illegal in some countries)
@@MehrumesDagon having a cane, crutch or walking stick isn't exactly what most people would consider being armed. Concealment of a weapon isn't done to trick others into attacking you so you can turn the tables it's done because you aren't supposed to have that weapon or in some cases any weapon. There is no need to hide something you are allowed to have. You get frisked before entering a place and nunchucks will get taken away, a cane will not.
There are knives plenty long to be comparable to nunchucks and if you want to argue range then a rock thrown or slung will do more than a nunchuck anyway and while people might think you are weird for having rocks in your pocket they aren't likely to take them from you.
Nunchuck aren't useless they just aren't good weapons.
@@MehrumesDagon You telling me that the average person looks at a man with a walking stick or cane and considers that person a real threat? You really telling me that?
Besides, if you want to conceal a chuck of any decent thickness under some clothes, you'd still need some pretty baggy clothes. And if you're walking around in warm weather with baggy clothes, you're gonna look suspicious. Really, I've tried hiding chucks underneath my gi before. And my gi was pretty thick and baggy. It stood out like a sore thumb. Those were practice chucks that were pretty thin too. I've seen people more successfully conceal large handguns.
You will get in trouble if you get caught with a chuck where you're not supposed to have weapons. But a walking stick? Not likely.
Stick still wins in overall concealability. Chucks, by their nature of being uncommon, start off with a disadvantage in concealability. In some US states, you'd probably have an easier time explaining why you have a gun in your pants than you would a chuck, especially considering that chucks are a very poor self-defense weapon. So with that in mind, the chucks would need superb concealment in other areas to make up for that starting disadvantage for them to even come close to other common options. And they don't. They're not the hardest thing to conceal, but they're also not the easiest. You'd likely have to stick them in a bag or something, as I already explained how it's actually much harder than most people think it is to conceal something of that thickness underneath common clothing. But a walking stick, you can keep out in the open and is a superior weapon.
Plus, in my opinion, walking sticks can look much cooler.
And the stick comes in so many more forms, so you might not even need to carry one to have one in easy access. Pipes, tree branches, tool handles, sports equipment, etc. Heck, a hard baguette could work too. The simplicity and commonality of the simple stick is a HUGE advantage for it. It means they're easy to get a hold of, easier to train effectively in, and less likely to draw suspicion. The chuck by comparison has so much to live up to to even be considered against the stick.
@@ermosazorius4279 Actually considering that one of biggest prominence of nunchucks was not-so-recent gangwars over on the other continent, once could say that actually, tricking oponent into attacking you when you are armed and they are not so, could be actuall intend of some people.
That also being said, in some neighbourhoods carrying anything resembling a weapon (walking stick included, unless you are elderly) would be a sign provoking an attack in the first place, in which case nunchackus would allow to have a means of abova-average-range of self defence, without actually drawing attention to yourself.
as for range - if you want a knife to have same striking range as nunchucks, then you are already having a "knife" that is considerably longer than single "half" of nunchuck which means not so easy to conceal.
As for throwing rocks - sure you may be able to toss a rock further than hit with nunchuck, but that won't keep oponent at range, or at least not for long enough for it to matter.
as for walking cane not being taken away - over here I am quite sure that unless you are elderly and in factuall need of that cane, football stadium security would take away your walking cane off you if you tried to get in with one. Tho to be completely fair, the stadium security in my city got such improved over last decade that good luck smuggling in any weapon through those guys.... but yeah they are talking walking canes off of people too.
@@ShadeSlayer1911 "You telling me that the average person looks at a man with a walking stick or cane and considers that person a real threat? You really telling me that? "
A young person that does not need it for aid in walking? yes.
on second paragraph - I have seen people very successfully concealing nunchucks, and just because you were unable to reproduce, does not mean it is impossible.
Also if you are having to explain why do you have an item on you, you already failed in concealing it, so I would not take anything requiring that point as "disadvantage in concealment"
And true, commonality of the stick means you can not bring a stick and still end up having one, but that is besides the point.
My Word... This is Good stuff. I am student of physics and the Long sword. Your arguments regarding momentum, impuls and Force över time is spot on. I have a small nuget though, a pondering. I am considering the posibillity of conservation of angular momentum. What we are looking for is speed to of set the lower mass and impulse deficiency, so.... Consider a nuncuk strike;, momentum is imparted - Speed is proportional via centripetal acceleration to radius. If you mid strike pull the strike close you will shorten your rotational radius and increase rotational velocity through conservation of momentum. Call it an increase in Speed at the expense of reach. Will it be enough to of set the mighty stick. I don't know.
Newton's 3rd Law: EQUAL and opposite forces. When a ball bounces it puts the SAME force on the ground that the ground puts on it. The ball looses energy to things like heat, sound, and deformation of the ball itself as well as any deformation to the thing it hits.
A great test visually would be to see someone hit a few baseballs with a nunchuck and then with a stick.
I bet the baseball hit by nunchuck will not come close to going as far as the baseball hit with the stick.
If the nunchuck mechanics were "superior" why would we not use them in place of baseball sticks.. I mean bats?
#teamstick
That's bc nunchucks aren't as precise or as strong.
They are more of a show off street level (no guns) weapon.
They are just.. quick and chaotic. Imo okey enough.
@Z. Michael Gehlke Nun chucks and trampolines are more comparable because they both have give to them. The ground and the stick are both solid, so force imparted by each has a greater effect. The technical physics explanation is circumstance dependent; the point the physics video was making was that a change in momentum is easier to cause with a longer duration. They weren't concerned with whether that change was more or less, only that it happened. The rigidity or kinetic linkage is ultimately a more important factor, which happens to cause the increase of duration.
@Z. Michael Gehlke Simply not true.
Seeing how far a ball would fly is a direct result of the force imparted on the ball and how much potential damage you could create to do damage.
As Shad said, you're simply operating a much smaller stick with no leverage when using a nunchuck.
Take a 1 meter stick and split it in two, you're now down to 50 cm of lethality versus 1 meter.
On top of that, you can apply your own body as part of the weapon if there is a solid link. So that 1 meter stick is closer to a 130 cm long weapon that's also slightly heavier depending on the mechanical force you can assert through your pose.
The nun chuck has non of this, due to it being disjointed.
In fact, if you THREW your stick, it would be comparable to the force you'd achieve with the nun chuck, except the stick will be twice the length and size, so a thrown stick is a much fairer comparison, but it would still win.
Thrown stick is ass compared to one used in your hands normally though. The mechanics you impart on the weapon is so much greater for the stick.
It really is simple physics. I'm sure someone a lot smarter than me could do the math of the speed the nunchuck would need, to even approach the same amount of kinetic energy a stick would have, to show it would beat a nun chuck, even without the human element in it.
@Z. Michael Gehlke He explained in his previous video who he reacted to why the nunchuck does not "whip". Its not even close to what a whip does.
@Z. Michael Gehlke Internal damage is directly proportional to travel distance. Unless the nunchucks can function as scissors that direct force from two opposite direction, how much damage the target takes is directly related to the energy transferred and inertia of the target, and the inertia of a baseball is fixed.
I have a very very hard time believing that Shad uploaded a serious video about nunchucks, which he knows is the most controversial point across his whole channel, on April Fools of all days
Fr tho:
Love your videos Shad
I think they are super super interesting and very entertaining.
Also thanks for a better momentum lesson than given by my physics teacher lol
You could do an easy experiment to show how sticks hit "harder" (transfer energy better) than nunchucks: have the stick fixed on one end and able to rotate and basically build a pendulum, putting a ball directly below it. Let it fall from a horizontal position and see how far the ball goes when hit, then do the same with the nunchuck and you will see the ball go a shorter distance.
You can actually see how the nunchucks fail to complete the transferral of energy at around 23:50. I think that they CAN hit *as hard* as a stick- they can produce almost just as much energy, as the statistics examples showed, but like Shad said, thats not the problem- the problem is *transferring* that energy.
A battery full of electrical energy is useless if your cable can't transfer that energy fast enough to run the tech it's wired to. Hell, a larger battery may hold more energy, and even be able to *technically* output more as a result- but if the cable it's using to transfer energy can't handle that much, or is too inefficient, the amount and output of that energy is basically rendered useless.
Only way we can solve this... gladatorial arena with two average people that have no combat or martial arts experience whatsoever. Last one standing who is wielding stick or knunchaku will be our answer.
Here's the physics breakdown in some detail:
- Momentum is mass times speed.
- Impulse is a change in momentum.
- A force acting for a certain duration will transfer momentum, and thus is an impulse.
- Impulse in this context is basically "amount of damage"
- If a higher force is acting for the same duration to transfer momentum, impulse is higher which means more damage
- If the same force is acting over a higher duration to transfer momentum, impulse is higher which also means more damage
- In the context of nunchucks vs stick, the mass to consider is the mass of the rigid body in motion
- For the nunchuck, the relevant rigid body in motion is the part above the linkage
- For the stick, the relevant rigid body in motion is the entire stick and some part of the person holding it
- The amount of momentum a stick/person has before impact is much higher for the same speed, because of the much higher effective mass for the stick/person rigid body
- Momentum is conserved during a collision, which means that the quantity of momentum before impact, the mass times the speed of the weapon's effective rigid body, is equal to the quantity of momentum after impact, the mass times the leftover speed of the weapon plus the mass times the new speed of the target
- The highest transfer of momentum would be achieved if the weapon has no speed after impact, hence no momentum, and the target has all of the momentum
- Because nunchucks are basically unable to have no speed after impact, which means that some of their momentum is not transferred into the target, and they start out with less momentum in the first place, because of the lower mass of their effective rigid body, there is no way that they could inflict an equivalent transfer of momentum as a stick which starts out with more momentum and may have no speed after impact
"this isn't a troll video to make fun of nunchucks" it's 1st of April. my trust issues don't allow me to believe you.
Shad, I really like your content and have a question that I'd like to see you cover, if possible.
One of my friends mentioned off hand that early Scandinavians during the Viking period unwittingly made crude steel by mixing the ashes of bones of family members or animals in the spiritual belief that it would make their weapons stronger, and the carbon present from the bones would bond with the iron and make a crude alloy.
I don't know how true this is, but I think it could be an interesting topic to make a video on!
Interesting, now I also want to see that in a video
Dragonbone weapons are basically dragon steel?
I love it.
Not only family members, they also used bones from animals to capture the strength of the spirit in the steel. (Allegedly.)
Finally an April Fools upload that is both great content and an intellectual shitpost
"[...]If nun-Chucks can hit as hard or harder than a stick of comparable size and weight[...]" - shows a stick that is much beefier than both parts of the nun-chucks in his oher hand combined.
...nobody ever equipped their army with nun-chucks. Case closed.
These discussions always remind me of a particular Mythbusters segment that has stuck out in my mind to this day. The segment involved testing a scene from the old Hellboy movie in which Hellboy slams his massive fist into the hood of a car coming at him, causing it to flip clean over him as a result. The test they devised involved dropping a large metal fist onto the hood of a moving car with the necessary momentum to impart the assumed force. While I understand it was likely the most viable test they were able to perform, I was immediately able to see how inaccurate to the original scene it was, and everything was centered around the "tennis match of forces" as you put it. (22:23 vs 22:27)
Yep, the higher velocity of Hellboy's hand would absolutely be necessary for a flip. (The punch still wasn't hard enough to flip a car, but a relatively slow object like the fist the myth busters were using couldn't achieve a similar result no matter how much mass it had.

Hey. This was really a non-meme vídeo. No unecessary jokes mixed in the analysis (yes, the Oz comment was necessary), tried to cover all the basis and properly explain the researched topics. Nice Work!
4:10 Just wanted to add to this by bringing up the law of cubes. The larger the object, the more volume and mass it has, but doubling an objects size does more than double the volume and mass. You can see this in action by dropping a mouse, a human, and a horse from a two store building (don't actually do this.) The mouse will be winded, but fine because it's mass is small enough that the force it absorbs is minimal. The human will also be fine, but may have a broken bone. The horse... well that's a pile of meat and bones. Btw the general force equation is Force= mass * acceleration. The different factors are added into each part depending on where they apply (like the constant pull of gravity.) The acceleration of gravity is 9.8 m/s/s, so in the mouse, human, horse example you can see why the force changes so much. As for the stick vs nunchucks debate, the main driving difference between the two is the mass. Having the ability to use the stick with torque is also a huge boon for the stick. More or less, the longer an object, the more torque (or rather the rotational force) it can apply. That kinetic chain is important.
There's a reasonable chance of death for a human falling 2 stories, and high likelihood of multiple complex fractures. Squirrel might be a better choice as they can survive their terminal velocity i believe.
your kidna close, but kinda not with your force equation. that equation is used to determine the netforce being applied to an object that is accelerating at a given rate (or determine how quickly an object will accelerate if a constant given force is applied to it.
in either case, the maginitude of acceleration due to gravity is largely irrelevant to how how much harm would befall your falling animals. what *is* relevant is the velocity they're able to achieve, and their individual masses (i.e. momentum) as well as how long it takes them to reach 0 velocity. *thats* the acceleration that matters. how quickly they go from falling to being flat on the ground. not how quickly they were accelerating while in the air.
@@mandowarrior123 that completely relies on how they land. A human landing feet first has a chance to literally walk away from it.
And so Shad continues with the saga, can't wait to see how it ends, this is the biggest most important moment of the century
I think we can clearly put to bed that nunchuks cannot and will never be able to transfer as much force into a target as a stick of equivalent length/size.
The follow-up questions I'd love to see tested is what is the actual energy required to get nunchucks moving to the velocity at which you start seeing diminishing returns, and then how much force you can deal with a stick, using that same amount of energy?
Is it easier to maintain use of nunchucks at it's peak force output for longer, compared to a stick?
Would love to see testing on ballistic gel dummies. Of course, the zombie version, so there's less chance of getting demonitised. (The Elder Gods of TH-cam: "Green blood is okay," as shown by Demolition Ranch and Kentucky Ballistics, recently. 😁)

That helps for soft tissue, but you'd probably need green wood for bone analogs.
@@patrickjanecke5894 The ones that they use have organ and bone analogs already. Can show pretty realistic damage.
Shad's assassin class is my favorite.
It would be really interessting to compare multiple different sticks to nunchucks,
1) with the same weapon reach and stick diameter of the Nunchuck, like shad is doing it here
2) (probably unnessasary) Same Weight and diameter , so a little shorter because the string gives reach with very little mass.
3 ) same backing/ equal cariing dimensions as a folded Nunchuck, same mass as complete nunchuk but only length of one nunchuk "arm"
4 ) half nunchuk, to fairly explore shads idea "rip it appart an use it as two short sticks"
There are a couple of things though.. 1) Would you always look for the strongest hit? From what I can tell, every one of those stick hits demonstrated would be deadly. If a burglar attacked me at home I would use a stick (there happens to be one nearby, for lowering the ceiling trapdoor), but I would not use deadly force. It's terribly painful with way less than full force. 2) The nunchuck *can* "reach around" something which the other person is trying to defend himself, the stick can't. 3) With nunchucks you avoid hand shocks, which *may* be good.. obviously there's less force, but ref. 1). 4) Obviously there's the huge risk of hitting yourself with that nunchuck, particularly if the other person does something you can't or didn't expect, and 5) You can't use the nunchuck to poke someone, which is one of the strategies I might want to utilize on that imagined burglar.
Indeed you can "hit around" a shield. But the force would be even less because the chain between the nunchuck is deformed! It can still deal some damage but may not be sufficient to incapacitate anyone, what then? By the time you recover a nunchuck to spin it again, you may be in trouble! Hitting around a shield can only intimidate an inexperienced person. A flail would do a better job at this because of its spiky end which could minimize the area of impact and, therefore, deliver more force into a smaller area.
Poking falls into the category of "versatility". Nunchuck is just so bad at versatility, which has been pointed out before.
I’ve never seen more dedication to disproving the nunchuck then this, but I approve
The Nunchuck has not been disproved.
It is same as idiots defending Russian mass murderers. Facts disagree against dedication. Tell me why American police use nunchaku?
The nunchuck falls in that category of weapons of convenience. In Eastern Asia there have been generally more bans on owning of proper weapons either by law or cultural norm. Back then no one expected to get attack by a guy using a grain flail. It has no merit other than sometimes being the weapon closest to hand (which is often the weapon best for self-defense).
Counter point, a walking stick is much more convenient than a pair of handicapped sticks with a strong emotional connection that you keep in your bag or belt.
And in the chuck norris movie the guru smacked the bad guy with a (old-fashioned desk model) telephone. And said pretty much the same thing. Use what you have.
@@glasletter3111 Sure but what if you're in a field and you can't run inside to get your walking stick.
@@geofff.3343 what kind of field has nunchucks but no sticks?
@@glasletter3111 Holly cow are we getting a little pedantic? A ninja might also use one because farmers are a common disguise and farmers use grain flails.
I think there is more to be said on the elasticity/hardness of the target in relation to the impact. For example, when swinging a stick against a concrete floor there is no advantage to holding it against the floor. No matter what there is rebound energy and it just depends whether that is potential energy of the stick bouncing up or vibration in your hands (or nunchuck hitting you in the face), either way its there. In a composite structure like the test dummy it can only deform so far before it becomes essentially a rigid structure. By following through you are adding additional force throughout the contact time allowing you to more easily overcome the elastic potential of the outer foam and have as much force as possible transferred to the rigid core. Either way stick does better due to more mass plus the mass of the person and the ability to follow through but contact time isn't exactly how you are portraying it.
Now I just want a video of nunchuck-lovers trying to defeat the literal floor in one on one combat using nunchucks...
Yes, he's got the concept of momentum a little backwards. You don't get more momentum transfer in an impact because you increased the contact time. The contact time increases because the material deforms when placed under higher stress, and that deformation increases the time it takes for the collision to complete. If you had perfectly rigid objects colliding the impact would be instantaneous no matter how much momentum was involved. But real life is squishy.
2:15 you make a big physics mistake!!!!!
What is transferred from the stick is energy. Kinetic energy to be specific. But energy isn't transferred to the stick it's sapped from it.
What the stick feels is the same force he applies. As per newton's third law of motion: action and reaction.
So when the stick hits the head, it stops moving as fast because the energy was passed to the head that was hit.
Maybe they made Michelangelo the way they did *because* Nunchucks are such a joke of a weapon. He's the comedian of the TMNT!
Gurantee someone is going to try to debunk this video without watching it/paying attention. Or just rely on petty insults.
Been rewatching Dardevil for the fourth time and the way they depict his sticks in the show is really cool in my opinion. It can go from being a billy club, to nunchucks, to a ranged projectile when thrown. Not to mention the cord that can be used as a grapple hook or to choke someone out. I know it's not "relevant" in the algorithm right now, but there's a lot of attention to detail in that show and all the Marvel Netflix shows that put the modern shows to shame. I'd be curious to see your coverage on them, or at least Daredevil. If not on this channel, maybe on Knight's Watch? A guy can dream. It's more refreshing than ever in this day and age where Disney is creatively bankrupt and the shows have such waning quality.
So Shad, today I got into my first actual sword fight. Let me just say, if I went into another one but without the sword I most certainly would rather use my fists over Nunchucks. Why? Cause they take too much frelling training to use and not hurt yourself.
I been using sticks, swords, chain spears and chuks for my whole life. Dont be mislead by this video. Im sure a katana does no more damage than a butchers knife in these test standards. A perfected whip with chucks takes firstly crafting the chuku measurements precisely to the dimensions of your body. Then adding weight to the ends of the chuku gradually while training until your bodies muscles and weight balance have adapted to the motion. Eventually using heavy metals will have the entire weight of that stick in the tip of a chuk. Then they crack like a lead whip and sound like a gun shot when they hit....but theres more chance of surviving a gunshot. PLUS... you can climb, jump and conceal them through any security. Try that with your precious swords looking like a dickhead. You can also throw'm away and make another pair in under an hour for less than $10. And they are useless in the hands of others. Compared to all other weapons. CHUKS WIN. FATALITY
An important part of the equation for the stick vs nunchuk which automatically makes the nunchuck worse is that when you swing the club you aren't just adding the sticks momentum. You are also adding your arm and a decent portion of your bodyweight into the swing.
