Newton’s Cradle Explained

Technically speaking he's talking about an isolated system. In a closed system energy could still transfer and because of entropy you could technically supercool the surrounding gasses into liquid and then at some point make them reach absolute zero, but in an isolated system energy could not be transfered through the system, and this would exist perpetually.

haha that was so simple but brought me so much joy, i don't know why 🤣

That’s just a metronome

Wherw is the Professor Walter Lewin!!!

i need more of this in my algorithm

But surely it wouldn't have the same speed because of energy loss

What would happen if you took all of them tho?

The noise is so satisfying

Via G-d's Hand (The external force) of faith.

Why does he look like doc ock?

"...We take the mass of three balls." as if the balls stayed in place, but their mass was stripped off😂

Keep this in my algorithm

playing with balls never gets old

so we just learned the more complicated way of this😭

First electroboom
Now this
I am truly grateful

Wow physics is amazing

Not same speed, speed is lost

I like balls

How would momentum be different if these balls were in a vacuum

opens comment
relieved

doesn’t 1 ball move more than 1 ball? It looked like it moved the 2nd ball a bit

Balls😂

I like how the blue ball gets eyes and mouth because of the lights

Bro said “sometimes called a newton’s cradle” 😂

Okay but something I still dont get: p=mv so it seems in this case the velocity, v, of the balls is variable but the mass, m, is invariant, meaning N balls in, N balls out, but why couldn't you have 1 < N ball come out at at higher velocity or M > N balls come out at lower velocity? This would still conserve momentum.
I assume this has something to do with conservation of energy (e.g. 0.5mv_0^2=0.5mv_1^2) but can someone help me out here?

I love this. This is how my brother-in-law taught me english, for billiards. It’s all physics, after all

What if all the balls had different weights? 🤔

hears balls ō_Ô bombastic side eye

You can also see here that there is rarely if ever. Perfect transfer of energy from one object to another or from one state of matter to another

"If i take three balls''🤨💀

Science, man, love it

I'm 41, I already knew this because I've been in a few offices in the 80's and early 90's.

Bro could’ve explained that with the small table version of the balls but decided to go full out

This is really cool! I’m so glad Newton invented momentum

The fun part is what does it mean to be a closed system. Science is so cool but can sure get confusing.

Momentum only stays the same in a perfect world. In the real world there are losses in energy so there is loss in momentum

is this a jojo reference?

With a newtons cradle you can forget the fundamental difference between three balls and two balls on your chin.

I love those things dude. They remind me of my grandpa

Why are they watching me 😢

What did I learn? Nothing

this is so awesome

Why can’t I do that with my “two balls”??smh sad that’ll be fun 😂

If my physics class was like this, I don’t think I would have hated my teacher 😢

Thank you for making these videos, big hug to you all

Nice demo but the energy going into the opposite ball is not exactly the same

Dude has a he him. Yes he knows what momentum feels like

The last one sounded like popcorn lol

Also you can take 1 ball from one side and 2 from the other side and let them go at the same time and it will also stay conserved

I have something the same as this but small and made for it
