5/6 Linear momentum has to be always conserved for the whole system rather than just the ball. Earth is part of the system too. If you look at the experiment that begins at 0:18, the linear momentum of the balls switch between +3mv (where m is mass of each ball) and -3mv. How is linear momentum being preserved? Well, the linear momentum of the rest of the system (the stand, the table, the building, the earth and so on) changes by 6mv as that for the balls switches between +3mv and -3mv.
6/6 Linear momentum for just the balls is constantly changing, e.g. at the point of the highest swing it is 0. The force of gravity makes this change happen. However during a collision linear momentum is preserved because of the highly elastic material the collision happens almost instantaneously. Change in momentum is force multiplied by time (near zero). Also direction of motions of the balls is perpendicular to gravity at collision time, so no gravity contribution to change in momentum.
I've always loved that about newtons cradles... Try using a pencil next time to add a ball into the bounce. It works a little easier than trying to get your hands in there w/o bumping or stopping the rhythm.
I remember I got one of this when I was a kid. People say this is very relaxing to study and work in an office. I used to play a little bit and finally I got rid of it... It makes me nervous that "clock clock clock clock clock" all the time xD
if you are starting with two balls each of mass m and velocity v,the total linear momentum becomes (m+m)*v=2mv..Then when it hit the other three balls ,the total linear momentum of 2mv is transfered along with the balls then why doesnt it becomes like the last ball of mass mm getting the velocity of 2v....the linear momentum of 2mv is also conserved here......
If you're asking why the third ball doesn't go up with the other two when you drop two at once, you basically said it yourself. The velocity is 2mv; it would only be able to swing the third one at a velocity of 3mv (I think). If you're asking why the last ball doesn't swing higher when you drop two from the other side... I'm not sure. Edit: I found a great video describing the physics of these: th-cam.com/video/dQw4w9WgXcQ/w-d-xo.html
firey_ No it isn’t. Why do you think it’s called Newton’s Cradle? It’s named after Isaac Newton, one of the greatest physicists and mathematicians of all time.
no duh man, im smart enough to fgure that out. im just saying the other alternative for the use, which as much as it is useful and contributional for science most people use it to kinda chill at work, or just put it on their desk at school, and while they're on a loading screen they kinda play around with it. i think you took me too seriously, chill bro (i dont mean to offend anybody by saying that i meant that in a friendly manner) so yea, while I definetly agree, its just my look at it ;p
2/6 In the above setting when you add the law of conservation of energy and law of conservation of linear momentum and the only solution for movement is what you see. For example at 0:18 there are 3 balls striking 2 balls each with velocity v, and the only possible solution that preserves both kinetic energy and linear momentum is that post-collision 3 balls continue moving in the same direction with velocity v. Remember that linear momentum is m*v whereas kinetic energy is 1/2m*(v-squared).
3/6 So the solution for the experiment at 0:00 can't be 2 balls on the right taking off at half the velocity each post-collision, as that would not preserve v-squared while preserving v. The only solution to preserving both v and v-squared is exactly the same number of balls moving in the same direction post-collision. Another example, at 1:41 preservation of linear momentum would be satisfied by all the balls coming to rest post-collision. However that wouldn't preserve kinetic energy.
4/6 There is no law of preservation of kinetic energy, just a law of preservation of total energy. However in this example, because the steel balls are so hard, total energy remains as kinetic energy rather than converting to other forms such as heat. If the balls were made of some other material, such as gummy bears and you did the same experiment that begins at 1:41, you would likely see that all the balls came to rest post-collision (preserving linear momentum but not kinetic energy).
fucking camera falling asleep on us.
XD
+Casey Clymore xD
+Casey Clymore xD
Just made my fucking day
Casey Clymore you know the camera's just had a long hard day
I'm sure that sir Isaac Newton is more then happy knowing people are playing with his balls to this very day.
🤨🤨🤨🤨
Bruh yer camera's tired af.
Gettit some shut eye.
dat calculation tho lol😁

I think it just slipped

Isaac Newton, you balls and your physics never ceases to impress
Lol the camera started falling asleep at 0:58

This guy is having too much fun playing with balls.
+ViperLordX :D
He walks up to Isaac Newton , and says" can I play with your BALLS?!?"
I do!
+ViperLordX Ok...
lmao
Wonderful. Some variations I had not seen before.
Newton has 5 balls?!

excuse me but i think thats my line

John Hughes I know right even the camera fall asleeps because of the boredom.

Blame sir Isaac Newton
To make this kind of video, you need balls of steel
Baron Trenk ba dum tish

Ofc
Specifically Newton's Balls of Steel
Every second Friday me and the boys have a few brews, line up our sacks and do this with our nads, it's such fun I suggest you try it.

This was so relaxing to watch... Omfg
Geez, Bro. Can you hold that camera still? Is the cameraman bored or hypnotized?
Mick Carson its really tired dude
These tricks are so cool! I want one of these.

I'm glad you're not playing loud and obnoxious music
This guy is going places
Could watch this all day!!

He's got balls of steel.
back in my old days, kids played with small metal balls on a string that swayed back and forth
You're such a good camerman
Wow camera, stay awake... :P
That's AWESOME!!!!!!!!👍👍👍

1:21 Did the camera operator fall asleep?
anyone else lean forward when the camera fell asleep
The ball reset is the best part of this video 😂
I didn't know Newton could do these tricks with his balls, thanks for the insight
coolest thing everrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr
my brain hurts
Sweet. Thanks for uploading.

Where can you get one of this in nowadays?
amazon?
Thanks,but I was wondering besides the Amazon or any online way.
Passwordcracks Thanks,but any way exclude the online shopping?
toy shops? Maybe home shops were you buy things for your home

Well Shit son. No one has seen these things omg. Im so satisfied and amazed of your skills
Nice Job!!
Thanks for the video, really interessting how physics behave.
I was waiting for him to use a ruler so they could start zig zagging
Cool nice job
These are the types of videos i like on youtube
wut....
better than the other tricks on youtube
Thats it fantastic 👌
Looks trippy.
Good quality top class best of the best👌👌
Wow these are cool
