As a unity dev, I can almost assure you that trying to simulate all of the newtons law 100% accurate would melt your pc, but for estimating physics at a decent framerate, it runs really great

For the newton’s cradle I’d recommend having it attached to two beams each, it helps keeps the balls aligned

i love how upbeat and positive you are and how calm i love your channel

This is also why the portal gun works exactly as expected. But that said it does specify that there are minimum and maximum safe things to simulate before the simulation becomes unstable. This is actually specifically written down in one of the various billboards that were intended for the museum. Actually something I've noticed is most of the pieces for the museum actually appear to be there for modders more than anything else. Some have to do with the new way to Avatar's work, some have to do with how to import mods by discreetly disguising it as a crate and pallet system for shipping stuff from the void but if you look at how a mod is packaged, your contents are put into crates or folders and then they get an item list that go into a file called the pallet, which when you zip it, it is in delivered, unpacked and loaded in. The fact that they describe so many of the operation of the simulation as physical things to be done in a way that also matches what you actually have to do to put stuff into the game is actually really cool. If you then interpret monogon as a publisher or shareholder, even the story makes a lot more sense.

Now this is a real science experiment, you planted the problematic, made a hypothesis, build the procedure, experimented, tried different scenarios to avoid unknown variables, and reached results in order to affirm the hypothesis. My nerd self really enjoyed the video!

This is now my favorite video on the Internet. Nicely done.

May not be entirely physics based but physics is definitely based

i think the reason the 3rd law didnt work, is because u didnt have 2 tethers on the top, i might try this and tell you if thats the reason it didnt work

dude i CANT get enough of your videos, holy molly your videos are really entertaining and every single time a finish a video of yours relating bonelab i always hop on afterwards, keep up the great content! definitely gonna growww

I could watch you paint a wall and it'll still be entertaining. You just have a vibe about you that radiates positivity. Your vids are addicting

I love how much you make these videos entertaining. I’m definitely subbing.

Last time I checked you were at 800 subs now 11k (keep up the good work)

This is a legendary video. Doing the work to know the stuff we really want to know

This is amazing!! Criminally underrated vid and game.

Super well done video, educating and fun!

great video idea bro! for sure worth a watch

for the newton's cradle, the balls are normally held by 2 strings, contricting one axis and lining them up. you only made on connection

The most educational video involving games I've ever seen

This is such a cool video dude make more like this please

btw the marrow engine is just an ik solver for your virtual body. at 2:08 thats just physx's joints. For the 3rd law, the way that physx will solve these collisions will depend on the order that they are simulated in, so the law most likely will be violated by the engine.

The fact that this actually helped with my physics exam and learned it the fun way😅

this is a really creative video idea

2:18 While it's true that F = ma, in this case that principle isn't really important, since acceleration is due to gravity and therefore constant for every object. If this was a physics simulation (in an ideal world of physics where there is no air resistance(drag)/friction/etc.) We would expect all the balls to roll down the hill at the same exact speed. The reason they don't in the game, is because I suspect drag is calculated in the physics engine. The more mass an object has, the better its momentum is able to overcome air resistance. Here F = ma actually is useful, since a is constant, a higher mass will mean the object is producing more force, meaning it counters drag force more effectively, since mass isn't a component of drag. Furthermore, this is why you experienced "weird results" when trying it with the player characters. Once again, in an ideal world of physics we would expect all of these characters to fall at the same rate because gravitational acceleration is constant and not dependent on mass (yes, fellow nerds I know gravity IS technically dependent on mass when you're at a very large scale, but for anything smaller than an asteroid we may as well define gravity as constant regardless of mass), however; since drag force is calculated, these characters fall at different rates. The same principle applies where you would generally expect characters with more mass to fall faster since they will have more force to counteract the drag, and we do see that the heaviest character falls fastest. However, the lightest character places 2nd, I believe this is due to them both having a smaller drag coefficient as well as less surface area than the character who fell slowest. The reason the balls rolled down the hill from heaviest to lightest is because they were all the same shape, so they would have had very similar (if not identical) drag coefficients. The large surface area of the bigger balls would slow them down a bit in the drag calculation, but their mass makes up for that.

2nd law, as best as I understand: -ignore friction... -mass, size, has zero effect on how fast something rolls/falls/slides -the only thing that determines how fast something rolls is rotational inertia (a hollow ring has high rotational inertia; a solid ball has low rotational inertia) -as i best understand, the reason is because the hollow hoop doesnt have much stuff that gravity can pull, but the solid sphere has lots of stuff that gravity can pull -the different weighted objects falling, ignoring friction, would all land at the same time. -the reason a heavy object doesnt fall faster, is because although it has more force (f=ma), it will also require more force for it to move. -now considering friction, -the avatars fell at different speeds probably because of their different drag/air resistance -afaik, the results for the ball ramp race are explained by the devs controlling their speeds on ramps only by angular drag, which afaik is the only practical way to simulate rotational inertia. mass played zero part in their speeds -the different objects might also have had different drag values apart from just angular drag kzfaq.info/get/bejne/mMtziLSX2da3oXk.html kzfaq.info/get/bejne/fKqmlqyms6vLn2Q.html kzfaq.info/get/bejne/hdVoh8SBu9nSaY0.html

On the swinging energy transmission test, you need two bars at the top, then two strings coming from each ball, and looping around the bars and connecting at the top, making it work better, but I don’t thing to can connect two constrainers.

I still dont get how you you only have 11k subs. this is too good

Excellent video

0:48 poor Ford he accidently did the splits, must have hurt

2:41 could be simulating air resistance if they don't land at the same time

very epic analysis

Very good researched and entertaining video😃👍

Love the video,love the game,love the engine and I love what your doing with it. 🤘

truly incredible

Sorry but I think you didn't internalize newtons second law correctly: "A force that acts on a body is equal to its mass mutiplied by an acceleration." Is not what you showed here. 2:31 Yes, different forces act on these different balls but they are all accelerated equally with g. Things like ground- and airfriction and different radii would influence which ball hits the ground first. If you were to roll down 5 balls with the same radius, without any friction BUT 5 totally different masses, they would all hit the goal at the same time because they're accelerated equally. The force that is applied to each one of these differs from ball to ball but is always equal to F = m * a. Altough the results for the falling characters where already false, same counts for them. Just because one thing has more mass than the other, doesnt mean that its falling faster. Classic practical example of newtons second law: kzfaq.info/get/bejne/gaqgZNeautm-p2w.html The accuracy of Unity is cool nevertheless especially because Unity doesn't directly use classic formulas for physics but rather simulates everything just by knowing every physical state in the previous frame!

Something to try with your newtons cradle I notice you were having issues stabilizing them. If you look at a newtons cradle the balls are not attached with one cable but rather two on equal fixed points. Would love to see you try this one again using two anchored points connected to each ball maybe that might help with the transfer of energy as it stabilizes things more?

Josalt has the most calming voice ever

Great video, one gripe YOU ARROWS DONT HAVE FULLY CROPPED BACKGROUNDS

for newton’s cradles you shouldve put some walls around it so that they wouldve stayed in line because the basketball one was working only once because they were movingout of place. You couldve recorded this using nimbus gun noclip mode

stress level zero’s team are a bunch of wizards if they’re able to make this properly run on the quest, goddamn

for the newtons cradle one you should connect the balls on 2 points as it does with the actual newtons cradle

This video was so satisfying.

Very well done and cool! Though I definitely feel the avatars and their controls, specifically abusing jump, is very strange and uses 'fake' added forces such that it's not realistic

The newtons cradle is absolutely one of the coolest here, that one ball acting properly is something you usually find in low level simulations, a single bounce is a great engine. Especially realtime. With enough time and effort from the SLZ team this "series" could run better. I wonder if boneworks rather than bonelab does this better? Its been pretty well established that boneworks physics is a bit better than labs.

epic, tip, newtons craddle's have the balls tethered at two points, which helps with alignment, but i think that two tethered points welds the balls solid to the place, haven't played bonelab yet 😥

Can you do a leverage lab? I thought about trying it but never had time

The character weight one might be for motion sickness reapsns

Loved this so much maybe to much

perfect excuse of a video to watch in class!

nice job chief

Good video, bro.

4th law: if I drop a google cardboard, it will fall, and I will be sad

i wonder how the physics in bonelab compare to the physics in boneworks, like if any of these tests work better or worse in boneworks

This is incredible

Tbh I think bonelab was less of a sequel to boneworks and more of a way to show off their new engine

The devs will definitely see this, and add a Newton’s cradle update later on down the road.

this is super cool

2:07 Seems like a limitation of the physics engine and not Marrow. But yeah, since joints don't actually have collision the connected ball structure doesn't really work.

At 2:25 you say that newton's second law implies that things with larger masses accelerate at a higher rate, however this is untrue. If the force is solely being provided by a gravitational force, then there is a mass term on both sides of the equation and they cancel out, meaning that every object in free fall around earth has an acceleration of approximately 9.8m/s^2

0:54 What moded map did you use?

if anyone asked "can you explain in bonelab terms?" this would be it

how do you attach blocks together like that?

For newtons cradle you should’ve tried baseballs

at first i thought that this video was completely fucking stupid but this was actually kinda interesting, great video

Nice 👍

I've played si many game that im sometimes surprised when real life doesent lag 💀😭

The newtons cradle would probably work better if the balls were attacked at two points

teacher: you will learn physics for great things me: i will also me:

3:50, the reason your newtons cradle is not producing ideal results is because of the model you have set up there, your test model is set with the balls attached to one string, but the real newtons crade has the balls attached to two, so they wont go side to side like they are in the video

How did u get these camera shots in game?

Physically linking a lot of rigidbodies was never stable in Unity. So inertia beads, chains, ropes, etc needs custom solution. Built in joints are not good enough to simulate this kind of things. The exact reason why you never see chains in Bonelab/Boneworks. But there are long sticks linked together and you can climb/swing on them. Long but few links works decent enough to have them in game

I love the idea of this video and your experiments are very cool but I have a few criticisms about it. Not a criticism but for Newton's first law the best example in BoneLab is the jumping system, they clearly put a lot of effort into this and it's honestly amazing. Your statement of "the object with the most mass will rolls down the hill the fastest" Is not very clear and not true. Fastest implies velocity is the highest meaning acceleration is the highest. With the rolling down the hill that has more to do with the radius and mass along with how it is distributed. The better test was the jumping from the ledge which based on F = Mg where g is constant they should have all hit the ground. The main difference would come in with air resistance which is a variable force based on the coefficient of friction. Light probably has the lowest Cf whereas strong probably has the highest, with very little difference. Overall the results you got indicate that there is some sort of air resistance, just keep in mind gravity is a constant acceleration NOT a constant force. For Newton's third law the Newtons cradle example isn't really good at demonstrating it at a surface level. Key word is surface. When you stand on a surface that proves that Newton's second law exists in some sense. BoneLab, being full body collisions you can simply push on an object and prove Newton's third law. You get pushed back and the object gets pushed forward. It's a great learning experience to play games like this, they clearly put a lot of effort into making it more realistic. I love games like this. Great video, keep up the great work!

yo im binging this at 2AM

Love the thumbnail

For the balls rolling down at different speeds, this is NOT caused by Newton's second law! Two objects of any mass fall at the same rate, the reason they accelerate at different speeds is because they have different moments of inertia, so the extra energy is going into rotational rather than translational kinetic energy!

I’ve learned more than I did in school lol

what camera mod are you using for the third person shots

wow im learning

yea

You need to test one more thing. You need to check the distribution of weight. For example, if you have one nail and sit on it, it will punture you. If you put many nails together and sit on it, you will be fine.

Daaamn so Bonelab does have physics. Who knew.

6/10 U actually tested Unity's physics engine, which is Nvidia Physics And also most physics engines in games are based on irl laws and formulas But still - nice video, very interesting to watch For future experiments you may want to use Unity Explorer mod for Bonelab, to position objects precisely

yes

Your newton's cradle builds lack the second cable / attach point. Try it with two constraints on each ball, making a V shape with the cables when you look at the line of spheres head-on.

0:59 map?

You misapplied Newton's second law for the test involving several balls rolling down the hill. They will indeed have different forces acting on them due to a difference in mass, but they each have the same acceleration (acceleration caused by gravity). The reason they rolled down at different rates is because of the different size balls, not their mass, which affects how they roll. A perfect test would involve different mass objects on a frictionless surface, and crashing those objects with a wrecking ball or something, to see how their different masses react to the impact by how far they slide

Man definitely listened to his 5th grade science lesson

Can you make a video about mobile VR station and you can get bone lab mods without A pc

Some one needs to do the same experiments in Half Life Alyx.

3:50 you used 1 tether instead of 2 for each ball. which is what that device was using before you tried doing it in bonelab. maybe you couldve gotten a better result.

🤓 (But this is actually really cool, great video)

VR science teacher

Can you test Garry's Mod or HLA physics?

I’m going to ask my mom if I can play Bonelab for physics

W video

Now i can tell my parents that I'm playing science games.😉

This is a certified 🤓 moment

my mind has 🤯i just watched this vid for some content not so nicola tesla school ngl

i heart jessica!

Bro turned a video game into school Not hate this realy was a good video nerdy but cool
