I love how everyone apparently chose to forget that there's a scene in the sonic movie where he goes so fast it seems like everything in the bar fight was almost completely frozen for nearly 3 minutes. To do that, while I won't calculate the actual value, it would mean that in any form (since this is base sonic who wasn't even supercharged), Sonic can move at speeds comparable to the speed of light. That mega EMP he caused pales in comparison to the actual physics behind the bar fight scene.
If he was moving for what seemed like 1.5 minutes (based off the clip) at what looks like a slow motion speed (maybe 5 m/s being generous) but the whole thing say actually a 1/100th of a second (because slight movement), he's moving at around 45,000 m a second Thats .015% the speed of light. I think you underestimate how fast light is. Even at the points he's bluring, and we're being really generous and saying he looks like hes moving 1000m/s, thats still only 0.3% the speed of light.
If he were moving at relativistic speeds, he would not see the rest of the world slow down. He would see it speed up. To an observer looking at Sonic, his relative time rate would slow down. That's the Lorentz transformation of time, otherwise known as time dilation. Hollywood doesn't seem to ever consult actual physicists on these matters...
@@MrJdcirbo Speed up is relative though At relativistic speeds they would speed up so they look like theyre always moving at around 0.33 nm a 'second' (second being counted in slow motion)

He doesn't. He's right handed, but in videos he is seen writing with his left. The footage is mirrored. This is why he never wears a shirt with a design on it.
He's not. They film it normally and then flip the image. He just wears symmetrical clothing to hide that fact, but you can sometimes tell when he's doing things that don't have writing on screen. Or you'll see the markers seem to switch between his left and right hand for no reason. He's right-handed.

@@markcochrane9523 And it ignores that Sonic's speed just seems fast because of how the game is designed so players can control him. In reality, he's not moving any faster than Mario.

Seriously speaking, he can: - Run past 8 universes in 8 hours. - Outrun a black hole without boosting. - Outrun a Bugatti Veyron. - Time travel somewhere. - Travel into a different dimension called "Bonus Levels".
simple math: day: 24 hrs steps 9 million: adopting an avarage step distance: .5 meters day in seconds: 86400 steps / second: 104,16 avg day speed: 52m/s i'm completelly disappointed. i'm pretty sure that in the sonic intro music says "sonic faster than light...", and in some fan forums, around 8 times i guess.
@@GrulbGL faster than LIGHT? yeah no. Sonic adventure 2 battle say's iconic music, Escape the city, sings: "Running around at the speed of sound", which I dont think they ever showed him go any faster in any media to be honest. Light speed is running something like 7 times around the planet in a second.
"Knuckles is cooler" You really are a supervillain to start THAT flame war in the comments. Some men just want to watch the world(or comments section) burn, don't they?
He is correct though... it is the real answer to that question. The war would start if you threw in Shadow and/or Silver. Still, Knuckles is the coolest.
Hey Kyle, love the show. At 6:27 you wrote the equation as V squared on the left, when the equation you used to calculate sonic's entrance velocity to be 27mph had just V, so it should have been v = sqrt(5gr). If that equation was to be correct (v^2 = sqrt(5gr)), then the rearrangement of the equation would have had V to the fourth power instead of V squared. Just covering all basis just in case one of the corrections was wrong. btw i love the cut off scream
@@Freyalise50 Thank you, everyone should thumb this so he sees this one. My math disagreed with him because he rewrote the equation wrong and I didnt notice immediately.
Sonic officially is about 5'11", Moved fast enough to escape a Black Hole (games), Moved fast enough to dodge lasers (games), and basically slid through dimensions (comics)
Kyle, there is one question ALL THREE OF YOU DUDES missed: What effect would Sonic's speed have on his environment. Things like: - What happens to the air when he hits those speeds? What happens to the air IN THE LOOP-DE-LOOP when he hits those speeds? - What happens to the track that he's running on when he hits those speeds? Could the various track elements even survive? - What happens to those rings and our blue dude when he goes to collect them? Would they shoot through him like bullets? And would they survive? - What would happen to all of those bad guys being that close to the blue dude? Would they survive? What injuries would they sustain? - Are there questions I missed? I'm guessing that the blue dude isn't going fast enough to significantly alter the planet's rotational speed or inclination in the solar plane. I'm also going to go out on a limb and say his effects wouldn't be as drastic as would be in a race between Superman and The Flash, but I don't think I want to be anywhere near him when he goes zipping by.
Hey dude he made this video to give us a rough idea about Sonic's velocity not about the effcts he will cause to surrounding, if he ran at his pick speed or hypersonic speed.
@@sameemsheikh2914 Except that the start of the video sounded like he might explore effects that the other two didn't talk about. The only thing he explored was how high of a loop-de-loop could Sonic run.
Okay, following your line of questioning, -How far would you need to be from Sonic's path to be safe ? What would be the effect of Sonic travelling through cities and towns? Would the structures be able to survive the blast of wind as he passed? If sonic were running to your rescue and picked you up, would you turn into a red mist like that girl from "The Boys"?
You always have such great energy for these episodes! If you used the debug mode in the original Sonic the Hedgehog game I think you wouldn’t have had to use an approximation for seeing how many Sonics the radius of a loop would happen to be ᕦ⊙෴⊙ᕤ purrhapps
Nice vid as always ;) In fact, Sonic could run through even bigger loops, if you stop assuming the gravitational force to be constant while increasing the distance between the Object and the earths mass Center. Especially for the 120km loop, this will surely make a Difference :)
Sonic Unleashed added a unique mechanic that: Measured ring energy collected Current speed Accelerated speed And achievable Mach speed / Max speed limit It's those little details, that give each adventure a unique experience for a player to dive into.
Can you explain what that centrifugal force is? From what I understand there isn't any centrifugal force at all on top of the loop, just an initial upward velocity gained earlier in the loop which temporary keeps Sonic on top of the loop but not forever. If there was a centrifugal force and a centripetal force equal and against eachother, Sonic can stand still on top of the loop and he will just keep going in the motion that he started with.
Interesting, but I was expecting a discussion of Sonic's speed exiting the loop because: Sonic is not a rollercoaster. The thing about rollercoasters is, they coast. They get their initial impetus from the first hill and expend that over the course of their, er, course, so a coaster entering it's loop wouldn't gain back as much energy from the pull of gravity on the other side thanks to losses to friction and the kind, though "circular coaster in a vacuum" noodling says the net energy over the entire loop should be zero. But Sonic is self propelled. He is constantly adding energy to the system so as to not coast to a stop. Even if Sonic doesn't add enough velocity to maintain a constant speed in his six meter loop, if he makes up for half the energy loss at the top of the loop, entered at 12m/s to reach a speed of ~9m/s rather than ~5m/s, when he exits he should be moving at between 15~16m/s(just figuring in me head, I'm sure someone will say with more accuracy). When you scale that up to your Super Sonic and Hyper Sonic speeds, wouldn't Sonic be moving at abominable speeds? Something around ~2200m/s for Hyper Sonic?
@5:12 Kyle mentions "If he's just spinning around a loop, continuing on his speedy way, not adding energy to the system...", so I suspect this is Sonic balled up in a "non-running" form. I guess it could be calculated if Sonic were running half-way up a loop and forms into a ball at the top (seeing as you can't run downhill faster than you can run without ow), but "half the energy loss" is kinda arbitrary and Kyle calculates both "always ball" and "always running" in a satisfying way.
It was average at best wouldn't call it great. Was just OK could have been better if it was more based on the game rather than that real world bs. Hopefully the next one better with more sonic characters I feel they would interact better with each other and feel like its a actual sonic movie not just a movie with sonic in it
@@zamon8erz10 The movie actually fits really well with the games and kinda creates a lot of explanations for stuff in the games... Its kinda good for a origin... And thats the thing you and ppl saying that this movie should had more of the games.. its a origin movie, it needs to happen on earth and explain Sonic personality as well eggman origin... It needed to be like that... And because of budget...
@@TGHunter probably more budget than anything else, like I sed was a OK movie I dint hate it tho the humor was a bit hit n miss with me. I just think it would have been better with more sonic characters, but the next one will clearly have more so it might feel more like a sonic movie if you get me. This plot could have been any game character in that place I feel, I don't know the sonic lore beyond the old cartoons and the first 2 sonic games so I might be missing a lot of the hidden nods to lore
@@zamon8erz10 "I just think it would have been better with more sonic characters" Sonic 1 is about Sonic and Eggman, and it needs a start for a new audience. By that logic Sonic 1 is less Sonic than other games... which is not true. "This plot could have been any game character in that place I feel" Not really, this fits Sonic really well and gives more explanation for the events from the 3D games. "I don't know the sonic lore beyond the old cartoons and the first 2 sonic games so I might be missing a lot of the hidden nods to lore" Oh god im sure you are, btw forget the cartoon for the lore part, they never were cannon, totally a spin-off thing. I really recommend playing some more games or just looking it up, this movie shows a lot of heart behind it and it really fits Sonic, even with his personality giving room for him to delevop a lot.
Hey Kyle, love the show and really enjoy your work, keep it up! Just a small error I spotted at 6:12. The square of the velocity doesn't increase with the square root of the radius (times constants), your left hand side of the equation was squared but the right hand one was not. Much love from Germany! And as I said: Please keep up the cool work :)
Hey show, love the Kyle! I had a question about stars and iron. If you were to throw solid iron into a star would in have the same "poisoning" effect that starts have naturally once they create iron themselves or would something different happen? Could never find this online anywhere, and was too late to the star episode to put it up when it happened.
I get where you're coming from but, no throwing a chunk of iron into a star wouldn't do anything to it. The reason why stars die when they start producing iron is that fusing iron gives you a net energy loss (consequently, producing elements heavier than iron in a star requires supernova conditions). Think about it this way, throwing a chunk of iron into a star won't affect whether or not that star still has hydrogen and helium to fuse. Hope that helps.
I'd say no, iron is just something a star can't fuse any further to create energy. If you threw a chunk of iron into a star it's like tossing a stone in your furnace, it won't burn but it won't put the fire out either. If you added a LOT of iron, though, you would probably speed the process up because its mass would increase.
Yo Kyle this question is about your falling video. What if you change something durability, and density to a drastic number. Would that object still shatter or explode on impacted from terminal velocity?
I think it would be REAL interesting if a video were made on who would be faster-The Flash or Shadow the Hedgehog. Sonic would be no match but I think even Shadow could give Flash a run for his money. The black hedgehog can run at near light speed after all.
@@ayyyjirachi6530 yes but Sonic needs Super Sonic form to even keep up. JUST on his OWN, Shadow can run at near light speed levels. When he's Super Shadow, he's damn near invincible lol. And say if we had Barry Flash vs Shadow.
@@AceHufflepuff Sonic runs faster than light in his base form. In Sonic CD he was traveling through time and in Sonic Generations he was able to restore color, life, and time to the zones he was running in. It was also confirmed by SEGA themselves that Sonic, Shadow, and Silver have the same speed...you can't wank Shadow and downplay Sonic.
Hey Kyle, greetings from Germany. If Sonic had enough speed to run into space, you wouldn't be able to apply earths acceleration any more which would further increase the radius, if I'm not missing anything Love the show, keep up with the cool content
Not really a comment about this show, but it always amazes me how you right all the equations backwards and right to left... I'd ad pretty well too... Was it hard to get used to? Regarless, keep up the good work Kyle! Love the show!
Key Kyle! Long time listener first time caller. Early in the video you say that Sonic isn't adding any energy to the system after he enters the system. While it is true that there is no energy from outside the system assisting him, Sonic wouldn't inherently run right up until he reaches the bottom of the loop and start rolling, but could continue running along the entire circumference of a loop to keep up his speed. This way he could either enter a loop slower and keep running in order not to fall at or before the peek of the loop or enter the loop at high speeds and then, after reaching the peek, continue running and accelerate to a speed faster than that at which he entered. The rate at which Sonic could accelerate and the amount of friction that he could apply the the loop would then be much more significant in determining how large a loop he could complete as he fights gravity on the way up the initial incline. Such speeds could create incredible centrifugal forces and, depending on Sonic's mass, could put the structure of the loop in jeopardy if his legs don't give way first. Because of this, I hypothesize that Sonic could potentially run around a loop with a diameter much larger than 120 km, so long as the loop were made of sufficiently strong materials.
Hey Kyle, love this show. For that final value you got for sonic traveling at hypersonic speeds, wouldn’t the actual diameter for the loop be greater than 120 km since sonic would be experiencing less gravity as he got closer to the border of space?
Most people wouldn't like the fact that he doesn't edit out his laughs but to me it makes the video feel real and makes him feel like a real down to earth person
hey kyle love the show. at 6:20 you accidentally put a square on the velocity, i was so happy because I thought I caught you slipping and could be a super nerd, but alas you corrected it again at 6:40 meaning you are correct. Giving me false hope, you truly are a villain
A loop reaching into space could be a really cool level, even if the loop takes minutes to complete you could just fill it with interesting stuff while the background gradually gets darker and satellites start to fly by
It's even more bonkers than that, because your equation assumes that gravity is constant, rather than decreasing proportionately to the distance away from the Earth's surface. I'm not sure exactly how you would go about factoring that into your equations, and it would probably make them way more complicated. Reality is awesome and messy. Thank you for another excellent episode!
Love the channel as always. Couple questions to consider: How fast are his feet moving? Twice the speed of himself? How many steps is he taking per second? (6 foot human = 2.5 foot stride. 2.5 foot creature = 1.25 foot stride. -1700 m/s = ~5600 ft/s That’s nearly 4500 steps per second, just roughly off the napkin. Not challenging him on the FitBit.) What amount of force is being applied to his feet to accelerate to those speeds? What about friction and how much that will slow him down after entering the loop at any given speed? Also, what about his inability and/or ability to continue to apply force to himself as he climbs the entry? No time to super nerd this all of them up.
Oh lets see well for the loop take the force required to move something that is roughly 3m in size and weighs about 30 lbs. For the friction? Well I don't know the exact speed reduction. His inability to add speed while he's going up the loop? Have you ever played a Sonic game and tried to go on a loop?
Hey Kyle. Love the show. There seems to be a math error at 6:12 where the Vtot should not be raised to the power 2 when the right hand side has a square root over it. Keep it up :)
HKLTS. When you're dealing with distances that go to space, you shouldn't treat g as a constant. Using the comparatively straightforward g=GM/r2, we can see that on Earth's surface (r= the 6,378.1 km from Earth's center) gravity exerts 341.923 Newtons on Sonic, but at an extra 120 km above the earth's surface that value drops to 330.375 Newtons. That's a decrease of 3.37%. Factor that in, and that means Sonic can get to 124.195km. Of course, that distance does decrease gravity's effects even further, by a little over 1 Newton. To actually draw up the most correct answer requires using calculus to find the limit, but at that point we should also be looking at what Sonic gains be running through thinner and thinner atmosphere and also the potential issues presented by not being able to breathe for a significant percentage of his trip, so I think I'm going to finish making lunch instead.
Even faster than that. Video game sonic shows FTL speeds. He’s outran a black hole while in space. This is a massively faster than light feat. Not only that in the comics he can move casually at 13 trillionths of a millisecond. Base form. He’s also traveled BACKWARDS IN TIME as a result of his speed. This is an immeasurable speed feat. Aka infinite speed. Since we know Speed= distance/time. Him traveling backwards in time as a result of speed would be immeasurable since you can not measure the time
Hey Kyle, I got home from a physics exam not three hours ago, and literally had this exact same loop question (finding minimum speed to stay on the top) you just did come up on it, but with a pilot in a plane instead of sonic on a loop. There weren't any little animals though. :( Good to know I got that question right, thanks for checking my work. Now I'm feeling watched. I'm onto you, Kyle Hevill.
Another great episode! Thank you. A few points however 1: the original Sonic from the movie was an abomination that never should have been created. They had so many reference models to use and didnt use them. The studio that was forced to fix it went bankrupt, so the people who did what they were asked lost their jobs because of this. 2: knuckles is in fact the coolest. 3: would Sonic pass out like you queried? Alternatively what would his body have to have (heart, special arteries, special organs) to survive the three different loops?
Hey, Kyle! Love your independently moving eyebrows and okay-ish impressions of animated characters. So, when you spoke of the speed of sound, at 8:09 being 343 m/s, perhaps you failed to include whether or not the altitude (or the temperature at that altitude) at which sound travels, since it isn't a constant. An example would be one I found on fighter-planes.com that states, "[a] plane flying at Mach 1.0 at sea level is flying about 1,225 km/h (761 mph), and a plane flying Mach 1.0 at 9.144 km (30,000 ft) is flying at 1,091 km/h (678 mph)."
Welcome Back, Kyle, missed your show. Just a quick googling* got me this equation Radial Acceleration = v^2 / r with that product (in m/s^2) divided by 9.8m/s^2 to get G's. So at the bottom of the initial loop you described Sonic would pull about 2.4489 G's with the top producing a measly 0.4959 Gs. For comparison, roller-coaster loops usually pull around 6 G's. Funnily enough, at all the speeds and heights you list, 2.5G seems to be, not quite a constant, but a good touchstone, as the Gforces only seem to *very* slightly increase as the speed/height factors go up. It was almost as if it were designed to be perfectly run by actual athletes or performers (think the ball cages with motorcycles inside them). I wonder if there was any research done by the Sonic team on this during their initial designs? Anyway, Love the show and thanks for brightening the work week, 13mins at a time.
You are the first person I have ever seen in a TH-cam video to use the term "centrifugal force" instead of "centripetal force" while still clarifying that it doesn't exist.
Welcome back. I was wondering if you could discuss some other channels's conclusions on a footnotes, like a "responds to" video, or something similar. For example MattPat recently looked at Link's strength and I was wondering if you could point out why you came to wildly different values.
When Kyle says "centrifugal force" I'm always remembering my physics teacher telling the class several times that there's only the centripetal force (because the centrifugal force is a pseudo force as it's only a thing we experience due to Newton's third law). Now I can't even hear the words "centrifugal force" without having shivers down my spine and my teacher's voice in my head. Anyways, I loved the show! (P.S I use they/them pronouns...)
From the perspective a stationary frame of reference (the loop), the centripetal force is what the loop feels from sonic flying through it and being accelerated radially. The centrifugal force is the pseudo force sonic feels in his moving frame of reference, equal and opposite to the centripetal force, Newton's third law; they are just 2 sides of the same coin.
Great episode Kyle! I think Sonic wouldn't need to be going at mach 5 to do a space loop. As he travels further away from earth's centre of gravity, the gravitational force and friction, impeding sonic's velocity, reduces the greater the altitude and so the energy required to move will be reduce. The benefit from the other end would be Sonic should be going faster at the apex of the loop (lesser resistance to his movement) which will increase his exit (3) velocity now that gravity is adding to his velocity on the reentry. Assuming he doesn't die from the friction and the compression of airflow, of reentry to earth. Sonic would become a living comet.
Hey Kyle love that you’re back... at 2:13 of the video wouldn’t there also be a Force Normal acting against Sonic (in the same direction as mg) at the top of the loop?
Sonic's size plays a big part of his speed. Plus he has less gravitational pull, which means when he's at the top sides of the loop he had less pull downwards, mixed with his speed make circular loopty loops a piece of cake for him. If they were any other shape he will have some issue because having to pause and change direction will cause him to lose momentum and fall. But that's just how gravity and physics works. Anywho.......... I'm sooooooo happy my favorite Science Sensei is back! I love the show and ONE DAY I'll be smart enough to be a SUPER NERD! (It's kinda my only goal in life that involves the internet) And Knuckles is the BEST! Shadow is a close second.
@ 10:00 -- 1974 days is the time difference between oct 2, 2014 (first episode of because science) and february 27, 2020 (this episode). and 282 is probably the number of because science episodes. Didn't know it was foreshadowed in this episode all along. Kyle has passed indeed.
Hey Kyle, Could we see the "appropriate" breakdown of Forces that would be acting on Sonic at the top of each loop (instead of the Centrifugal stand-in)? Thank you so much! -a Math Nerd

That assumes that the original games - or any of the games for that matter - have accurate physics.

Well, we know he can take 9 million steps in a day

In all his comics he doesntbhave a top speed just a max acceleration which he improves over time.

day: 24 hrs
steps 9 million:
adopting an avarage step distance: .5 meters
day in seconds: 86400
steps / second: 104,16
avg day speed: 52m/s
i'm completelly disappointed. i'm pretty sure that in the sonic intro music says "sonic faster than light...", and in some fan forums, around 8 times i guess.
@@GrulbGL faster than LIGHT? yeah no. Sonic adventure 2 battle say's iconic music, Escape the city, sings: "Running around at the speed of sound", which I dont think they ever showed him go any faster in any media to be honest.

Hey Kyle, love the show. At 6:27 you wrote the equation as V squared on the left, when the equation you used to calculate sonic's entrance velocity to be 27mph had just V, so it should have been v = sqrt(5gr). If that equation was to be correct (v^2 = sqrt(5gr)), then the rearrangement of the equation would have had V to the fourth power instead of V squared. Just covering all basis just in case one of the corrections was wrong.
btw i love the cut off scream
V to the 4th actually. V squared squared would be to the fourth power.
@@Freyalise50 Thank you, everyone should thumb this so he sees this one. My math disagreed with him because he rewrote the equation wrong and I didnt notice immediately.
@@Freyalise50 thanks for the correction, ita been a long time since I've done maths,
after checking: it's supposed to be v=sqrt(5gr), and not v². v² should equal 5gr (which is what he used for further calculations, so no prob there)
@@irgyn he still wrote the equation down wrong though at 6:27
This youtube channel is pure gold,the references,the maths,the jokes.
I mean how can someone be a huge nerd while being really really cool?
1:09 Dude - er I mean discount Thor , Jim Carrey was the best thing in the first Sonic trailers .
lasarith2 - AGREED! No idea what Kyle was on there.
Totally agree!
He never said he was bad or anything. He's talking about Jim Carrey's ridiculous ability to ad-lib... in a trailer nobody liked.
Sonic officially is about 5'11", Moved fast enough to escape a Black Hole (games), Moved fast enough to dodge lasers (games), and basically slid through dimensions (comics)
Kyle, there is one question ALL THREE OF YOU DUDES missed: What effect would Sonic's speed have on his environment. Things like:
- What happens to the air when he hits those speeds? What happens to the air IN THE LOOP-DE-LOOP when he hits those speeds?
- What happens to the track that he's running on when he hits those speeds? Could the various track elements even survive?
- What happens to those rings and our blue dude when he goes to collect them? Would they shoot through him like bullets? And would they survive?
- What would happen to all of those bad guys being that close to the blue dude? Would they survive? What injuries would they sustain?
- Are there questions I missed? I'm guessing that the blue dude isn't going fast enough to significantly alter the planet's rotational speed or inclination in the solar plane. I'm also going to go out on a limb and say his effects wouldn't be as drastic as would be in a race between Superman and The Flash, but I don't think I want to be anywhere near him when he goes zipping by.
Hey dude he made this video to give us a rough idea about Sonic's velocity not about the effcts he will cause to surrounding, if he ran at his pick speed or hypersonic speed.
You're getting Super Nerd, I'm calling it now
*Speed Force hand wave*
@@sameemsheikh2914 Except that the start of the video sounded like he might explore effects that the other two didn't talk about. The only thing he explored was how high of a loop-de-loop could Sonic run.
Okay, following your line of questioning,
-How far would you need to be from Sonic's path to be safe ?
What would be the effect of Sonic travelling through cities and towns? Would the structures be able to survive the blast of wind as he passed?
If sonic were running to your rescue and picked you up, would you turn into a red mist like that girl from "The Boys"?
You always have such great energy for these episodes! If you used the debug mode in the original Sonic the Hedgehog game I think you wouldn’t have had to use an approximation for seeing how many Sonics the radius of a loop would happen to be ᕦ⊙෴⊙ᕤ purrhapps

hey kyle, love the show! literally earned my like in about 30 seconds by bringing up the two channels that even led me to find your channel!
Oh hey, you're back!
Nice vid as always ;)
In fact, Sonic could run through even bigger loops, if you stop assuming the gravitational force to be constant while increasing the distance between the Object and the earths mass Center. Especially for the 120km loop, this will surely make a Difference :)
03:52 and here we go again with that damn imperial unit measurement ... ok. 12mph = 19.3Km/h
Whats fumny is USA doesnt us miles it used US miles. Lmao
I am guessing that the vast majority of his viewers are in the US so is that really so surprising?
So I guess the “5.4 meters per second” mentioned just before that doesn’t count?
I like it when you ask us to solve the problems ourselves. Very interactive.
I like how we aren’t just finding out Sonic’s speed, but using it in a cool way.
It refreshing AND it doesn’t 1000% destroy everyone’s childhoods.
Sonic Unleashed added a unique mechanic that:
Measured ring energy collected
Current speed
Accelerated speed
And achievable Mach speed / Max speed limit
It's those little details, that give each adventure a unique experience for a player to dive into.
2:28 So glad you pointed that out! Centrifugal is just something stopping a centripetal force
Can you explain what that centrifugal force is? From what I understand there isn't any centrifugal force at all on top of the loop, just an initial upward velocity gained earlier in the loop which temporary keeps Sonic on top of the loop but not forever. If there was a centrifugal force and a centripetal force equal and against eachother, Sonic can stand still on top of the loop and he will just keep going in the motion that he started with.
@@nicholasking2221 I just realized... that explanation only works on a spinning disc. NVM
Interesting, but I was expecting a discussion of Sonic's speed exiting the loop because: Sonic is not a rollercoaster. The thing about rollercoasters is, they coast. They get their initial impetus from the first hill and expend that over the course of their, er, course, so a coaster entering it's loop wouldn't gain back as much energy from the pull of gravity on the other side thanks to losses to friction and the kind, though "circular coaster in a vacuum" noodling says the net energy over the entire loop should be zero.
But Sonic is self propelled. He is constantly adding energy to the system so as to not coast to a stop. Even if Sonic doesn't add enough velocity to maintain a constant speed in his six meter loop, if he makes up for half the energy loss at the top of the loop, entered at 12m/s to reach a speed of ~9m/s rather than ~5m/s, when he exits he should be moving at between 15~16m/s(just figuring in me head, I'm sure someone will say with more accuracy).
When you scale that up to your Super Sonic and Hyper Sonic speeds, wouldn't Sonic be moving at abominable speeds? Something around ~2200m/s for Hyper Sonic?
@5:12 Kyle mentions "If he's just spinning around a loop, continuing on his speedy way, not adding energy to the system...", so I suspect this is Sonic balled up in a "non-running" form.
I guess it could be calculated if Sonic were running half-way up a loop and forms into a ball at the top (seeing as you can't run downhill faster than you can run without ow), but "half the energy loss" is kinda arbitrary and Kyle calculates both "always ball" and "always running" in a satisfying way.

The Sonic movie was actually really good.😂
It was average at best wouldn't call it great. Was just OK could have been better if it was more based on the game rather than that real world bs. Hopefully the next one better with more sonic characters I feel they would interact better with each other and feel like its a actual sonic movie not just a movie with sonic in it
@@zamon8erz10 The movie actually fits really well with the games and kinda creates a lot of explanations for stuff in the games...
Its kinda good for a origin... And thats the thing you and ppl saying that this movie should had more of the games.. its a origin movie, it needs to happen on earth and explain Sonic personality as well eggman origin...
It needed to be like that...
And because of budget...
@@TGHunter probably more budget than anything else, like I sed was a OK movie I dint hate it tho the humor was a bit hit n miss with me. I just think it would have been better with more sonic characters, but the next one will clearly have more so it might feel more like a sonic movie if you get me. This plot could have been any game character in that place I feel, I don't know the sonic lore beyond the old cartoons and the first 2 sonic games so I might be missing a lot of the hidden nods to lore
@@zamon8erz10 "I just think it would have been better with more sonic characters"
Sonic 1 is about Sonic and Eggman, and it needs a start for a new audience.
By that logic Sonic 1 is less Sonic than other games... which is not true.
"This plot could have been any game character in that place I feel"
Not really, this fits Sonic really well and gives more explanation for the events from the 3D games.
"I don't know the sonic lore beyond the old cartoons and the first 2 sonic games so I might be missing a lot of the hidden nods to lore"
Oh god im sure you are, btw forget the cartoon for the lore part, they never were cannon, totally a spin-off thing. I really recommend playing some more games or just looking it up, this movie shows a lot of heart behind it and it really fits Sonic, even with his personality giving room for him to delevop a lot.
Hey Kyle, love the show and really enjoy your work, keep it up!
Just a small error I spotted at 6:12. The square of the velocity doesn't increase with the square root of the radius (times constants), your left hand side of the equation was squared but the right hand one was not.
Much love from Germany! And as I said: Please keep up the cool work :)
Hey show, love the Kyle!
I had a question about stars and iron. If you were to throw solid iron into a star would in have the same "poisoning" effect that starts have naturally once they create iron themselves or would something different happen? Could never find this online anywhere, and was too late to the star episode to put it up when it happened.
I get where you're coming from but, no throwing a chunk of iron into a star wouldn't do anything to it. The reason why stars die when they start producing iron is that fusing iron gives you a net energy loss (consequently, producing elements heavier than iron in a star requires supernova conditions). Think about it this way, throwing a chunk of iron into a star won't affect whether or not that star still has hydrogen and helium to fuse. Hope that helps.
@@mikhailkalashnikov7886 yes actually. Thank you.
I'd say no, iron is just something a star can't fuse any further to create energy. If you threw a chunk of iron into a star it's like tossing a stone in your furnace, it won't burn but it won't put the fire out either.
If you added a LOT of iron, though, you would probably speed the process up because its mass would increase.
Gaming Elementalist no, in simple terms it’s not the iron that does this but the running out of fuel that isn’t iron, as far as I know
Happy to help!
Yo Kyle this question is about your falling video. What if you change something durability, and density to a drastic number. Would that object still shatter or explode on impacted from terminal velocity?
I think it would be REAL interesting if a video were made on who would be faster-The Flash or Shadow the Hedgehog. Sonic would be no match but I think even Shadow could give Flash a run for his money. The black hedgehog can run at near light speed after all.
Super Sonic could move that fast as well tho also which version of flash are we talking about cause depending on that determines if shadow is relevant
Ribotto Studios My answer is you’re a cutie Ribotto 😍
@@ayyyjirachi6530 yes but Sonic needs Super Sonic form to even keep up. JUST on his OWN, Shadow can run at near light speed levels. When he's Super Shadow, he's damn near invincible lol. And say if we had Barry Flash vs Shadow.
@@AceHufflepuff lol yeah if so if we use Barry idk maybe pre crises he'd be faster but it would still be pretty fun to see
@@AceHufflepuff Sonic runs faster than light in his base form. In Sonic CD he was traveling through time and in Sonic Generations he was able to restore color, life, and time to the zones he was running in. It was also confirmed by SEGA themselves that Sonic, Shadow, and Silver have the same speed...you can't wank Shadow and downplay Sonic.
Hey Kyle, greetings from Germany.
If Sonic had enough speed to run into space, you wouldn't be able to apply earths acceleration any more which would further increase the radius, if I'm not missing anything

“Big ring energy” is the new big d energy
Key Kyle! Long time listener first time caller.
Early in the video you say that Sonic isn't adding any energy to the system after he enters the system. While it is true that there is no energy from outside the system assisting him, Sonic wouldn't inherently run right up until he reaches the bottom of the loop and start rolling, but could continue running along the entire circumference of a loop to keep up his speed. This way he could either enter a loop slower and keep running in order not to fall at or before the peek of the loop or enter the loop at high speeds and then, after reaching the peek, continue running and accelerate to a speed faster than that at which he entered. The rate at which Sonic could accelerate and the amount of friction that he could apply the the loop would then be much more significant in determining how large a loop he could complete as he fights gravity on the way up the initial incline. Such speeds could create incredible centrifugal forces and, depending on Sonic's mass, could put the structure of the loop in jeopardy if his legs don't give way first. Because of this, I hypothesize that Sonic could potentially run around a loop with a diameter much larger than 120 km, so long as the loop were made of sufficiently strong materials.
Hey Kyle, love this show. For that final value you got for sonic traveling at hypersonic speeds, wouldn’t the actual diameter for the loop be greater than 120 km since sonic would be experiencing less gravity as he got closer to the border of space?
Most people wouldn't like the fact that he doesn't edit out his laughs but to me it makes the video feel real and makes him feel like a real down to earth person
After seeing the latest video on the channel, now I understand what you meant at 10:00 when you wrote... "Kyle has passed".
I’ll miss you bro hope your new channel becomes as famous as this one

8:27 - Okay, now I need to see Sonic in a wind tunnel at NASA ...
That sounds awesome. Hey maybe a challenge for a later video
3nertia
Same here
A loop reaching into space could be a really cool level, even if the loop takes minutes to complete you could just fill it with interesting stuff while the background gradually gets darker and satellites start to fly by
I would absolutely love a Part 2 where you try and see just what *_SUPER SONIC_* could do
That would be REALLY entertaining!
It's even more bonkers than that, because your equation assumes that gravity is constant, rather than decreasing proportionately to the distance away from the Earth's surface.
I'm not sure exactly how you would go about factoring that into your equations, and it would probably make them way more complicated. Reality is awesome and messy.
Thank you for another excellent episode!
Kyle, why not use time dilation to determine the speed of Sonic during the bullet time sections in the Sonic movie?
That's the first thing that I thought of when I saw the episode about sonic speed.
Someone already did that and they calculated that in that scene alone he ran about 667,000,000 mph.
The speed of light is 670,616,629 mph he was almost going light speed
This is the best TH-cam channel ever and this is my favorite episode.
Love the channel as always.
Couple questions to consider:
How fast are his feet moving? Twice the speed of himself?
How many steps is he taking per second?
(6 foot human = 2.5 foot stride. 2.5 foot creature = 1.25 foot stride.
-1700 m/s = ~5600 ft/s
That’s nearly 4500 steps per second, just roughly off the napkin. Not challenging him on the FitBit.)
What amount of force is being applied to his feet to accelerate to those speeds?
What about friction and how much that will slow him down after entering the loop at any given speed?
Also, what about his inability and/or ability to continue to apply force to himself as he climbs the entry?
No time to super nerd this all of them up.
Oh lets see well for the loop take the force required to move something that is roughly 3m in size and weighs about 30 lbs. For the friction? Well I don't know the exact speed reduction. His inability to add speed while he's going up the loop? Have you ever played a Sonic game and tried to go on a loop?
Hi Kyle, great show! I plugged in the speed of light in your formula and got around a 0.2 light year loop. Talk about amazing structures!

Hey Kyle. Love the show. There seems to be a math error at 6:12 where the Vtot should not be raised to the power 2 when the right hand side has a square root over it.
Keep it up :)
HKLTS. When you're dealing with distances that go to space, you shouldn't treat g as a constant. Using the comparatively straightforward g=GM/r2, we can see that on Earth's surface (r= the 6,378.1 km from Earth's center) gravity exerts 341.923 Newtons on Sonic, but at an extra 120 km above the earth's surface that value drops to 330.375 Newtons. That's a decrease of 3.37%. Factor that in, and that means Sonic can get to 124.195km. Of course, that distance does decrease gravity's effects even further, by a little over 1 Newton. To actually draw up the most correct answer requires using calculus to find the limit, but at that point we should also be looking at what Sonic gains be running through thinner and thinner atmosphere and also the potential issues presented by not being able to breathe for a significant percentage of his trip, so I think I'm going to finish making lunch instead.
Even faster than that. Video game sonic shows FTL speeds. He’s outran a black hole while in space. This is a massively faster than light feat. Not only that in the comics he can move casually at 13 trillionths of a millisecond. Base form. He’s also traveled BACKWARDS IN TIME as a result of his speed. This is an immeasurable speed feat. Aka infinite speed. Since we know Speed= distance/time. Him traveling backwards in time as a result of speed would be immeasurable since you can not measure the time
Long time no science bro. Welcome back.

Hey Kyle, I got home from a physics exam not three hours ago, and literally had this exact same loop question (finding minimum speed to stay on the top) you just did come up on it, but with a pilot in a plane instead of sonic on a loop. There weren't any little animals though. :( Good to know I got that question right, thanks for checking my work. Now I'm feeling watched. I'm onto you, Kyle Hevill.

6:30 the equation has both a squared on the left and a sqrt on the right
Another great episode! Thank you.
A few points however
1: the original Sonic from the movie was an abomination that never should have been created. They had so many reference models to use and didnt use them. The studio that was forced to fix it went bankrupt, so the people who did what they were asked lost their jobs because of this.
2: knuckles is in fact the coolest.
3: would Sonic pass out like you queried? Alternatively what would his body have to have (heart, special arteries, special organs) to survive the three different loops?
10:45 How can there be another episode?
Hey, Kyle! Love your independently moving eyebrows and okay-ish impressions of animated characters.
So, when you spoke of the speed of sound, at 8:09 being 343 m/s, perhaps you failed to include whether or not the altitude (or the temperature at that altitude) at which sound travels, since it isn't a constant. An example would be one I found on fighter-planes.com that states, "[a] plane flying at Mach 1.0 at sea level is flying about 1,225 km/h (761 mph), and a plane flying Mach 1.0 at 9.144 km (30,000 ft) is flying at 1,091 km/h (678 mph)."

Welcome Back, Kyle, missed your show. Just a quick googling* got me this equation Radial Acceleration = v^2 / r with that product (in m/s^2) divided by 9.8m/s^2 to get G's. So at the bottom of the initial loop you described Sonic would pull about 2.4489 G's with the top producing a measly 0.4959 Gs. For comparison, roller-coaster loops usually pull around 6 G's. Funnily enough, at all the speeds and heights you list, 2.5G seems to be, not quite a constant, but a good touchstone, as the Gforces only seem to *very* slightly increase as the speed/height factors go up. It was almost as if it were designed to be perfectly run by actual athletes or performers (think the ball cages with motorcycles inside them). I wonder if there was any research done by the Sonic team on this during their initial designs? Anyway, Love the show and thanks for brightening the work week, 13mins at a time.

Tony Hawk Fans: REEEEEEEEEEEEEEEEEEE -
Welcome back. I was wondering if you could discuss some other channels's conclusions on a footnotes, like a "responds to" video, or something similar. For example MattPat recently looked at Link's strength and I was wondering if you could point out why you came to wildly different values.
When Kyle says "centrifugal force" I'm always remembering my physics teacher telling the class several times that there's only the centripetal force (because the centrifugal force is a pseudo force as it's only a thing we experience due to Newton's third law). Now I can't even hear the words "centrifugal force" without having shivers down my spine and my teacher's voice in my head.
Anyways, I loved the show!
(P.S I use they/them pronouns...)
From the perspective a stationary frame of reference (the loop), the centripetal force is what the loop feels from sonic flying through it and being accelerated radially. The centrifugal force is the pseudo force sonic feels in his moving frame of reference, equal and opposite to the centripetal force, Newton's third law; they are just 2 sides of the same coin.
why was that necessary to include?
@@dane1382 it's like the vegan problem, he can't walk into a room without shouting it what he uses for pronouns
Great episode Kyle! I think Sonic wouldn't need to be going at mach 5 to do a space loop. As he travels further away from earth's centre of gravity, the gravitational force and friction, impeding sonic's velocity, reduces the greater the altitude and so the energy required to move will be reduce. The benefit from the other end would be Sonic should be going faster at the apex of the loop (lesser resistance to his movement) which will increase his exit (3) velocity now that gravity is adding to his velocity on the reentry. Assuming he doesn't die from the friction and the compression of airflow, of reentry to earth. Sonic would become a living comet.

Wait a second... a centrifugal force? Don't you mean a centripetal force? (2:34)
I love the show :-)
F
Hey Kyle love that you’re back... at 2:13 of the video wouldn’t there also be a Force Normal acting against Sonic (in the same direction as mg) at the top of the loop?
Sonic's size plays a big part of his speed. Plus he has less gravitational pull, which means when he's at the top sides of the loop he had less pull downwards, mixed with his speed make circular loopty loops a piece of cake for him. If they were any other shape he will have some issue because having to pause and change direction will cause him to lose momentum and fall. But that's just how gravity and physics works. Anywho.......... I'm sooooooo happy my favorite Science Sensei is back! I love the show and ONE DAY I'll be smart enough to be a SUPER NERD! (It's kinda my only goal in life that involves the internet) And Knuckles is the BEST! Shadow is a close second.
@ 10:00 -- 1974 days is the time difference between oct 2, 2014 (first episode of because science) and february 27, 2020 (this episode). and 282 is probably the number of because science episodes.
Didn't know it was foreshadowed in this episode all along. Kyle has passed indeed.
Hey Kyle,
Could we see the "appropriate" breakdown of Forces that would be acting on Sonic at the top of each loop (instead of the Centrifugal stand-in)?
Thank you so much!
-a Math Nerd

Mr.Kyle: *V* Top = 0.5 × G(r), *V* Bot^2 = 0.5 (5gr) & r = *V* Bot^2 / 5g. solve Sonic's speed with either formula, or fail the class.
