Any deaths this video were surely because I wanted you to look at this lovely game for longer, and definitely not because I'm bad at the game. You should be thanking me for my service. :)
I think the one pink thing you missed was the one you got and died with as soon as you got to the next level. It looked like the arm killed you before it could register you collected the thing
I think the feather you missed is the last one. You got it and moved to the next screen but before the feather got absorbed by the egg, the mechanical arm punched through you. I guess the feather then got canceled and you need to get it back again.
If this was the case, he would only have 4 by the end. There must be another in a hidden area, maybe that one part of the map that went up but that Tyler couldn't find a way to access
By my count, there were 5 feathers in this video, at the following times: 0:45 1:00 2:50 3:10 8:05 Further, Tyler went through a screen transition with the final one, which should have saved it. I'm fairly sure we never saw the 6th.
The reason eggs break when hitting to ground and not when it is thrown is because there is more force when it hits the ground. Yes, the speeds of the egg when it leaves the hand and hits the ground should be the same (neglecting air resistance), but by throwing the egg, we allow it to get up to speed for a longer period of time. When it hits the ground, it's only a matter of maybe 0.01 seconds for it to go from top speed to stationary, but we may throw the egg from rest to leaving the hand in 1 second. As another example, consider if the egg hit something that can absorb the fall better. It would allow the egg to decrease in speed much slowly than hitting a hard surface. As the saying goes, "it's not the fall that hurts you, it's the sudden stop at the end".
I'd argue that there's more force(energy) put into the throwing of the egg, since whilst in flight, like you said, there are air and gravitational resistances that absorb some energy before the flight is terminated (depending on environmental conditions and the direction of the throw). Instead, consider the concentration of how the energy is delivered. A hand is soft with lots of surface area contact the egg and distribute the force over a larger area, as well as like you said, the amount of time allowed for the egg to absorb the energy from the throw and impact respectively. It's a matter of how the force is concentrated.
Essentially, its an impulse thing: the impulse on both sides are the same but impulse is force integrated through time so a longer time means a shorter force per unit time
Comparing "throwing" with "landing" isn't really a fair comparison. When you throw an egg upwards, your arm does a pretty long motion. To compare it more accurately, you would probably need to shoot it out of some cannon or something alike. A really sudden start followed by an equally sudden stop. If the egg survives the launch, it should probably survive the fall.
@@electricheisenberg5723Hey come on now he may be a genius at puzzle games but that doesn't mean he has to be good at physics *suddenly remembers polybridge* _wait a minute_
Cushioning is just the material slowing down the deceleration of the egg. Since the egg instantly leaves the ground when jumping, there is no gradual acceleration, it instantly speeds up to full speed. This means that the forces acting upon the egg when jumping would be just as much as hitting the hardest possible surface when landing.
@electricheisenberg5723 throwing an egg in the air is much different from an egg “jumping” off the ground under its own power. In order to jump, the egg must push itself off the ground, but when throwing the egg, the acceleration is significantly less sudden.
It’s also about the impulse. If you can stretch out the time of the change in momentum, you can reduce the maximum acceleration and therefore the maximum force experienced. Tyler is right to point out that the energy to launch the egg is the same as when the egg falls. Whether the egg breaks, however, depends only on the maximum force experienced, and there are a multitude of ways to do the same amount of work but with different maximum forces.
this is the most random relation but this reminds me of an ooooold time travel game called "Thanks For Playing" where you cannot fall from up high, but for a totally different thematic reason - the game is taking place in reversed time so to "fall from up high" would mean "jumping impossibly high" in rewinded time and cause a time paradox. it's cursed and I wonder if you've heard about it hahaha
if we get many mechanics focused around the feeling of the surface that would be sick a soft cushin surce that doesnt crack you no matter what a rough surface that cracks you from even the smallest drops a hot surface that boils you if you stay on too long a lot of stuff
One reason for not shattering is that the launching force may be aplied to the entire egg, but the landing is a single point. It is impressive how mouch weight you van stack on four eggs with 8 bottle corks (plastic) on the top and bottom.
Really awesome game, especially for a single-dev project! I can see inspirational elements from Celeste being taken, especially with the way the feather collectibles work and the claw chase scene, corresponding to strawberries and Oshiro.
Yup I was thinking the exact same at the very start of the game like hmm might have inspiration of celeste, than came the feather collectibles and also the chase scene
1:36 there are plenty of ways that the jump could be more controlled than the landing, like if the egg is able to spread out the acceleration across a greater distance, or specifically brace itself in a way that prevents damage.
So yes, the energy absorbed by an object when landing is more or less equivalent to the energy that was released when it "jumped", (assuming that the take off and landing points are equal) however, quite often the case is that the device for expending the energy to lift off is not quite as efficient at absorbing the energy from the landing. There are a plethora of other factors to consider as well, but i think this satisfies your inquiry
Very cute game from one of the Peglin designers. I'm looking forward to the full game. Peglin also got a UI overhaul recently, along with a small roundrel rework with some fun new status effects and orbs. Look forward to seeing you try it out. The updates an experimental beta right now though.
The physics can only really make sense if egg propels itself upwards using only expanding force from itself, not pushing off the ground. Imagine jumping in real life by only extending your legs and not pushing off the ground, it is incredibly difficult though. If the egg was filled with springs which would absorb the initial jumping force and also produce the jump by suddenly releasing the energy, that could theoretically allow the egg to jump so high while not being able to withstand a small impact elsewhere. That’s one theory, another would be that the egg has a much larger area that it jumps from, which could allow it to output more force while minimizing the pressure it would receive from the force produced. While it falling from a height would put the force on a smaller surface area part of the egg or land on something that would increase the pressure exerted. A third theory is that the egg doesn’t believe in physics, and so the laws of nature do not apply to it. This is further reinforced by the egg itself being alive, rather than the chick inside it.
this concept could lead to some really intresting meta puzzles down the line with maybe setup up block positions or entry points from other levels bunburrows-esque, love the demo so far though theres a lot of potential here
There was an old game called "within a deep forest", its a platformer eith a bouncy ball, which can change its state, one of the states was the glass ball, very similar with this game.
Seeing as you’ve been playing lots of new games on your channel, I recommend Hades. It’s not the type of rogue like you normally play on you channel since it’s an action game instead of a puzzle game but it is one of the few games I’ve seen no one say anything bad about it.
It kinda doesn't really fit the channels theme though Won't say the game is bad, but gameplay wise it lacks variety. Am going to eventually finish it only for the sweet sweet lore
Tyler- for the physics, its very clear he has the capability of telepathically creating pressure differences in the air but he can only do this in when going upwards or anytime in sideways directions. This is how he goes upwards without going through incredible g's and has air control. This is true because he is an egg of a bird and birds can fly. He is using telepathic bird wings that have restrictions.
1:30 That entirely depends on what exactly the egg is. It is possble that it has tiny invisible legs that are much more durable than the shell, but can't guarantee landing on them. Similar to how you can, land on your feet from 2m without being hurt, yet falling on your head from standing position can still kill you.
The egg breaking on impact but not jump can make sense if you do not treat it as a point mass. The floor limits the deformation that the jumping force and air do not, introducing different structural stresses than the jump.
Tyler, while the total impulse of the collision has to be the same as the impulse of the takeoff, the force does not have to be the same. Impulse can be calculated by multiplying the force exerted by the time that the collision takes. In other words, a collision that takes more time has lower force. For instance, as you jump up, you spend a significant amount of time with your legs extending. If you land with your legs locked, they will be contracting for a very short amount of time, so the force of impact will be much larger than the force of takeoff. Of course, eggs don’t have legs to jump or absorb impact, but maybe a similar mechanism is in place
Yes, throwing an egg will not break it, but in this case the egg receives an instantaneous force when jumping, as if it was smacked by a tennis racket. Regardless, typically in games, accurate physics are secondary to good gameplay.
This is actually the _exact_ concept I had for my first game that i made last year as part of my computer science course. So cool to see how many things are similar, and what things are done way better than my little tech demo.
I wanna see a speedrun of this. Usually in platformer speedruns the speedrunner would try to make the furthest jumps possible to waste as little time as they can on going up/down instead of forward, but in here the jumps you're even allowed to make are very limited
"If the force on landing is enough to break you, so is the force required to jump" Technically true, though you could argue that since the egg has no legs jumping and instead just magically accelerates, it could be feeling that force of acceleration over the whole volume. Landing is a force applied only to the point that hits the ground, meaning it will stop moving while the rest of the egg continues, causing it to break. But if the whole thing accelerates equally, then it won't break. If you take this to the logical extreme you end up with those weird ideas about putting fighter jet pilots in oxygenated water so they can do really sharp turns because the water around them is the same density as a human body, roughly
Takeoff and landing forces of leaping strepsirhine primates by John Fleagle 1999 (not proper citation I know) indicates that takeoff forces end up being higher than landing forces due to additional force needed to activate the compliant mechanism required for jumping. The forces may be distributed in different ways while jumping than while falling however. The fact the egg can jump already indicates it has some method of locomotion. That same locomotion may diffuse the force across the entire eggshell preventing shattering.
The reason why the egg doesn't break going up is because (presumably) all of the upward momentum isn't put on the egg at the exact same time. Falling is so dangerous because the ground leaves little to no time to decelerate, whereas even in a gun, a bullet takes time to get up to speed
My thought on the egg not shattering on launch is that it could be considered time taken to launch. If the "jumps" accelerate for a second, while the impact provides the same amount of force over a tenth of a second, the resulting effect is ten times worse on the second one when compared to the first.
You're missing that acceleration happens over time and distance giving a "cushion" where as deceleration from landing happens instantly for the egg. Landing is much harder than launching for the egg.
The egg probably has a curved speed (if you would imagine a chart) when jumping, but when falling it's speed goes linear because egg goes with gravity so it grows to a high value, and then sudden impact happens which releases half of that force back into the egg. Not a physics graduate so maybe I'm wrong. I did have physics classes in college.
Physics wise, you can imagine that it somehow takes off with an acceleration that's not instant, but the instant deceleration of landing can't be coped with
I would say that the egg does not shatter on jump becouse the air resistance is not big enough to generate a stoping force that is strong enough to break the shell of the egg. you can accually check that by throwing the egg upwards in home Tyler.
@@Aliensrock that also brings up a question of how is the egg moving since if we assume the yolk of the egg is just pushing the egg from the inside why can't we say that the yolk is just pushing the egg up and the shell is just more tough when stretched instead of when squashed (like reverse concrete)
It depends on how you jump. When landing, all the force of stopping is applied only to the point of contact. How an egg jumps, however, could be very different. If the force of the jump is applied to all parts of it equally it would not break from jumping.
The reason you don't crack when taking off is because there's less impact when you jump. Impact is more relative to the "jerk" a.k.a, change in acceleration, than the acceleration itself, that's why you can throw an egg as hard as you can at a trampoline or a net and it still won't break.
The force of the launch doesn't necessarily have to match the impact force, because of air resistance. Take a 9mm handgun shot upwards for example, the terminal velocity when falling (~200mph) is much slower than the muzzle velocity (~800mph). That can still kill someone if it lands on them though, don't fire guns in the air randomly.
Literally first thought was about An Untitled Story, another game where you play as an egg although I think that one was a bit more indestructible. Thank you for unlocking a random memory from my past. Also this game looks fun as heck.
I dont think youd necessarily need to exert the same force to take off as you would to land, at least not over the same period of time. The reason the egg splats when it hits the ground is because the floor has no give, and so the egg deccelerates all at once and breaks. When the egg takes off, we can assume its at least a little bit elastic and pushes itself off the floor. Think of it like bending your knees to jump, and then landing without bending your knees at all.
Impact is when the egg breaks. The impulse (force times time) must be the same, but on the impact there is a smaller time before the shell buckles. The real question is how it jumps without being able to stretch or bend the egg
I'm sure other comments have tried to explain this, but the reason an egg wouldn't shatter on the initial jump but would on landing is due to acceleration. It's the same reason accelerating to 60mph in a car is safe but crashing at 60mph is not -- it's not the speed that kills, but the sudden change. The higher the acceleration, the more force is being imparted in the moment. Remember too that acceleration can be a negative change in velocity. It also may be due in part to how the egg experiences these forces -- during acceleration, it may have the force spread across its entire shell, or at least the posterior side relative to its direction of movement. On landing, however, the same force would be applied to a much smaller area of the shell. This could explain why an egg that accelerates and decelerates at the same rate only shatters on impact. However, we must also consider that this egg has a face on it. I don't have a source for this, but I believe most eggs in the modern age do not have faces. If it is indeed meant to be a real egg, it might be safe to assume this egg is from the eurasian steppes or the foothills of the Ural mountains, though it may indeed be from central asia. If that is indeed the case, be careful with this game, and be sure to count the eggs you get from the grocery store from here onward. Odd numbers of eggs are a bad omen, and you might want to contact a local religious institution or poison control center if you find you've come home with such a number. They don't forget faces.
Isn't force mass*acceleration, so if the egg would spend longer accelerating than it does decelerating it could be possible that the egg doesn't break whilst jumping but does whilst falling. That is the reason you need a mat to land on whilst high jumping, you have your legs accelerating in half a second or so, but if you would land on concrete you'd decelerate in a fraction of a second and get hurt
I wake up and immediately check my phone to see if you posted!, keep up the good work and maybe continue chants of sennar, I sense potential for a series
Shoot, I was hoping for some more Chants of Sennar today. However, I have been wondering what else the Peglin team has been working on, and who better to showcase that than the Alien’s Rock?
Technically speaking, essentially any video game character that jumps should rip themself apart instantly; energy equals mass*acceleration, and acceleration can be calculated by dividing the total speed gained by the time over which it was gained. Because most games simply apply a jump’s speed instantaneously, that makes time in our equation 0, or effectively 0. We would have to divide the vertical velocity gained by 0, or a number that is infinitesimally small, which would give us an insane amount of energy, if not an infinite amount, being put into our character. We’ll just have to assume the game skips over a couple frames where they wind up :)
it isn't the force that would crack the egg eggctly. Rather, it would be the impct (which of force over time). That means that if the force of jumping if over a larger amount of time than the force of the floor when he lands, then he this would work. This could be becasue the internal mechaism he uses to jump applies force not instantly, but his shell doesn't bend much, so he can't disperse the force when he lands.
if the egg had some kind of ability which allowed it to lower it's mass before it attempted a jump but couldn't use it when it's falling down that could rationalize the physics inconsistency I mean it is an egg that can jump, so I feel like it doesn't need much rationalization personally, but that could be a method
If the water will be part of the game there are 2options: Minecraft Water - magically cancels fall damage. Real Water - hits you hard like a concrete wall.
If while jumping you accelerated over a period of time, then the force would be less as force = change in momentum/change in time, and momentum = mass x velocity, and velocity = distance/time. So if you went up 2 metres in 1 second, your velocity would be 2m/s. If your mass is 1kg then your momentum would be 2 Kgm/s. If while jumping you accelerated over a period of 0.5 seconds, then the force would be 4N. Alternatively, when hitting the floor on falling, you stop much quicker. A falling object accelerates at ~10 m/s^2 so from 2 metres, using v^2 = 2gh, the egg would hit the floor at ~6.3/s. It’s mass is 1 so it’s momentum is ~6.3kgm/s. Now let’s say it stops in 0.1 seconds, 6.3/0.1 = 63N of force. So although Newton’s 3rd law sates every action has an equal and opposite reaction, if it is spread out over a longer period of time, it can have less force and do less damage. (Also I’m pretty sure somewhere my calculations were wrong, maybe I should have multiplied the 4N by 10 to get 40N bc of gravity or something, idk, but anyway still less damaging to jump than land, hence why people can jump perfectly fine but if they don’t bend their knees when landing, can injure themselves)

"If the force on landing is enough to break you, so is the force required to jump"
Technically true, though you could argue that since the egg has no legs jumping and instead just magically accelerates, it could be feeling that force of acceleration over the whole volume. Landing is a force applied only to the point that hits the ground, meaning it will stop moving while the rest of the egg continues, causing it to break. But if the whole thing accelerates equally, then it won't break.
If you take this to the logical extreme you end up with those weird ideas about putting fighter jet pilots in oxygenated water so they can do really sharp turns because the water around them is the same density as a human body, roughly
Takeoff and landing forces of leaping strepsirhine primates by John Fleagle 1999 (not proper citation I know) indicates that takeoff forces end up being higher than landing forces due to additional force needed to activate the compliant mechanism required for jumping.
The forces may be distributed in different ways while jumping than while falling however. The fact the egg can jump already indicates it has some method of locomotion. That same locomotion may diffuse the force across the entire eggshell preventing shattering.
The reason why the egg doesn't break going up is because (presumably) all of the upward momentum isn't put on the egg at the exact same time. Falling is so dangerous because the ground leaves little to no time to decelerate, whereas even in a gun, a bullet takes time to get up to speed
My thought on the egg not shattering on launch is that it could be considered time taken to launch. If the "jumps" accelerate for a second, while the impact provides the same amount of force over a tenth of a second, the resulting effect is ten times worse on the second one when compared to the first.
Tyler: look at me, im an egg!
Aliensegg: *casually dies*

It's about impact. You can throw an egg without breaking it but it will crash onto something if hard enough.
You're missing that acceleration happens over time and distance giving a "cushion" where as deceleration from landing happens instantly for the egg. Landing is much harder than launching for the egg.
The egg probably has a curved speed (if you would imagine a chart) when jumping, but when falling it's speed goes linear because egg goes with gravity so it grows to a high value, and then sudden impact happens which releases half of that force back into the egg.
Not a physics graduate so maybe I'm wrong. I did have physics classes in college.
How tf did he not catch “fail damage” faster…….. 🤦🏽♂️😂
Tyler the amount of good content you put out is crazy, watching toque vids is a habit now
So that's the egg Tyler never has when he stumbles upon Peglin chef on the second floor
Physics wise, you can imagine that it somehow takes off with an acceleration that's not instant, but the instant deceleration of landing can't be coped with
The boss fight reminds me of the Oshiro boss from Celeste. The wave of nostalgia just hit me. I can't believe how long ago you played it wow
I love these puzzle platformers with some weird jump mechanic, and this game somehow reminds me of elechead, one of my favourite platformers.
I would say that the egg does not shatter on jump becouse the air resistance is not big enough to generate a stoping force that is strong enough to break the shell of the egg. you can accually check that by throwing the egg upwards in home Tyler.
The air resistance isn’t the problem, the problem is that the egg would “have to” exert force on the ground to jump in the first place.
@@Aliensrock I mean yea but also, now that you have compleatly destroyed my argument I will proceed to change the topic pretending I was not wrong.
@@Aliensrock that also brings up a question of how is the egg moving since if we assume the yolk of the egg is just pushing the egg from the inside why can't we say that the yolk is just pushing the egg up and the shell is just more tough when stretched instead of when squashed (like reverse concrete)
It depends on how you jump. When landing, all the force of stopping is applied only to the point of contact. How an egg jumps, however, could be very different. If the force of the jump is applied to all parts of it equally it would not break from jumping.
Next update: the egg now shatters upon launch, good luck! 😊
Getting revenge on the egg for never showing up when you get the chef
The reason you don't crack when taking off is because there's less impact when you jump. Impact is more relative to the "jerk" a.k.a, change in acceleration, than the acceleration itself, that's why you can throw an egg as hard as you can at a trampoline or a net and it still won't break.
The force of the launch doesn't necessarily have to match the impact force, because of air resistance. Take a 9mm handgun shot upwards for example, the terminal velocity when falling (~200mph) is much slower than the muzzle velocity (~800mph). That can still kill someone if it lands on them though, don't fire guns in the air randomly.
speaking of peglin, it's about time for your monthly peglin upload
Literally first thought was about An Untitled Story, another game where you play as an egg although I think that one was a bit more indestructible. Thank you for unlocking a random memory from my past. Also this game looks fun as heck.
this is a wonderfully original game concept!
I was about to write a 2 page essay on why the physics would not work but at then i saw it was a sentient egg and it changed my live forever.
You might also like "An untitled story", it's about an egg and was made by the same dev who made Celeste
I dont think youd necessarily need to exert the same force to take off as you would to land, at least not over the same period of time. The reason the egg splats when it hits the ground is because the floor has no give, and so the egg deccelerates all at once and breaks. When the egg takes off, we can assume its at least a little bit elastic and pushes itself off the floor. Think of it like bending your knees to jump, and then landing without bending your knees at all.
Impact is when the egg breaks. The impulse (force times time) must be the same, but on the impact there is a smaller time before the shell buckles. The real question is how it jumps without being able to stretch or bend the egg
I'm sure other comments have tried to explain this, but the reason an egg wouldn't shatter on the initial jump but would on landing is due to acceleration. It's the same reason accelerating to 60mph in a car is safe but crashing at 60mph is not -- it's not the speed that kills, but the sudden change. The higher the acceleration, the more force is being imparted in the moment. Remember too that acceleration can be a negative change in velocity.
It also may be due in part to how the egg experiences these forces -- during acceleration, it may have the force spread across its entire shell, or at least the posterior side relative to its direction of movement. On landing, however, the same force would be applied to a much smaller area of the shell. This could explain why an egg that accelerates and decelerates at the same rate only shatters on impact.
However, we must also consider that this egg has a face on it. I don't have a source for this, but I believe most eggs in the modern age do not have faces. If it is indeed meant to be a real egg, it might be safe to assume this egg is from the eurasian steppes or the foothills of the Ural mountains, though it may indeed be from central asia. If that is indeed the case, be careful with this game, and be sure to count the eggs you get from the grocery store from here onward. Odd numbers of eggs are a bad omen, and you might want to contact a local religious institution or poison control center if you find you've come home with such a number.
They don't forget faces.
Physics nerds will be happy. the smaller the fall from the apex of the jump, the lower your downward velocity when you land. Good game.
On the physics bit: the acceleration when junping isn't necessarily identical to the acceleration of gravity so the force isn't the same.
Isn't force mass*acceleration, so if the egg would spend longer accelerating than it does decelerating it could be possible that the egg doesn't break whilst jumping but does whilst falling.
That is the reason you need a mat to land on whilst high jumping, you have your legs accelerating in half a second or so, but if you would land on concrete you'd decelerate in a fraction of a second and get hurt
You had me at "From the makers of Peglin"
I wake up and immediately check my phone to see if you posted!, keep up the good work and maybe continue chants of sennar, I sense potential for a series
Tyler, tbh, I only buy games that you play, those being peglin, balatro and chants of Sennaar. Thanks a lot man
every Celeste player is happy in 4:20
comf
Shoot, I was hoping for some more Chants of Sennar today. However, I have been wondering what else the Peglin team has been working on, and who better to showcase that than the Alien’s Rock?
Next Sennaar episode will be Monday!
@@AliensrockScore!
Technically speaking, essentially any video game character that jumps should rip themself apart instantly; energy equals mass*acceleration, and acceleration can be calculated by dividing the total speed gained by the time over which it was gained. Because most games simply apply a jump’s speed instantaneously, that makes time in our equation 0, or effectively 0. We would have to divide the vertical velocity gained by 0, or a number that is infinitesimally small, which would give us an insane amount of energy, if not an infinite amount, being put into our character. We’ll just have to assume the game skips over a couple frames where they wind up :)
it isn't the force that would crack the egg eggctly. Rather, it would be the impct (which of force over time). That means that if the force of jumping if over a larger amount of time than the force of the floor when he lands, then he this would work. This could be becasue the internal mechaism he uses to jump applies force not instantly, but his shell doesn't bend much, so he can't disperse the force when he lands.
if the egg had some kind of ability which allowed it to lower it's mass before it attempted a jump but couldn't use it when it's falling down that could rationalize the physics inconsistency
I mean it is an egg that can jump, so I feel like it doesn't need much rationalization personally, but that could be a method
If the water will be part of the game there are 2options:
Minecraft Water - magically cancels fall damage.
Real Water - hits you hard like a concrete wall.
speedruns of this game must be hilarous
Considering that looked like a sewage pipe at the end, I think I might know what broke the egg's fall...
Really there’s a fully acceptable, reasonable, and logical reason why the egg doesn’t shatter on take off:
Because f that. Egg puzzle babyyyyy
The only thing I could think about while watching this video is how heavily inspired by celeste it is
Eggcelent eggsecution from one eggnurmously fun egghead just cracking the shell of this demo.
I can’t wait for people to speedrun this when it’s actually out lmao
you can always tell when a video is sponsored, no matter who it is playing
So the egg from Peglin finally gained some sentience and ran away to avoid the chef. Guess no more cake relic.
Great video 👍
What? You egg? *She stabs him.*
Maybe this'll finally be the run where Tyler gets the egg to the peglin chef.
4:23 - People who don't know: Haha, funny
People who know: 🗿
Technically, landing force is slightly less than take-off force, because air resistance and such.
Reminds me of the glass ball from "Within a Deep Forest"
This game seems really fun to play. It reminds me of Celeste and Inside, mixed together.
for me it seems more like The End Is Nigh
7:33 SAFEWAY->supermarket->Egg
I'm very curious about this game's lore
1:30
No
You could slowly bring the egg to a height of whatever then throw it down and watch it shatter
The force is not the same
But the work may be
Here lies Eggbert Legbreaker.
His last words were "Lets Play Dizzy!"
If while jumping you accelerated over a period of time, then the force would be less as force = change in momentum/change in time, and momentum = mass x velocity, and velocity = distance/time.
So if you went up 2 metres in 1 second, your velocity would be 2m/s. If your mass is 1kg then your momentum would be 2 Kgm/s. If while jumping you accelerated over a period of 0.5 seconds, then the force would be 4N.
Alternatively, when hitting the floor on falling, you stop much quicker. A falling object accelerates at ~10 m/s^2 so from 2 metres, using v^2 = 2gh, the egg would hit the floor at ~6.3/s. It’s mass is 1 so it’s momentum is ~6.3kgm/s. Now let’s say it stops in 0.1 seconds, 6.3/0.1 = 63N of force.
So although Newton’s 3rd law sates every action has an equal and opposite reaction, if it is spread out over a longer period of time, it can have less force and do less damage.
(Also I’m pretty sure somewhere my calculations were wrong, maybe I should have multiplied the 4N by 10 to get 40N bc of gravity or something, idk, but anyway still less damaging to jump than land, hence why people can jump perfectly fine but if they don’t bend their knees when landing, can injure themselves)
the feathers are like collectables, they (probably) don't do anything
