Bowling Ball Elastic Collisions

Equal mass elastic collision demos using bowling balls. Shows that in one dimensional elastic collisions, equal mass objects exchange velocities.

This 2 mins of explanation takes my teacher about a week. Excellent demo, sir. We except teachers like you

[IvanPotapov]

Thank you, prof. Burns. Your visualisations and explanations are extremely spectacular.

[zainabmohamazubair]

Thank you very much, Professor! What an excellent demonstration!

[ricardofigueroa]

Good job, thank you! So much better when we can see it in action.

Why is there so few physics teacher doing this experiment? That's a mistery to me. Pendulum is almost always used with a single pendulum and Newton's craddle which is much more complicated. This configuration should be employed much more. This is how third law was born or corroborated.
Newton knew that speed is approximatly proportional to the cord between the rest position and lower point. This would be usefull to discuss the choosen and obtained velocities after each colisions.
0:31 a moving ball and a ball initially at rest with aproximate exchange of velocities
1:24 simetrical configuration with oposite velocities
1:37 unequal velocities (lower ball has about half cord and speed is therefore half the other ball in the collision)

0:36 identical mass, elastic collision.... interchanges velocity, the one that was at rest now moves while the one moving comes to rest. im in 11th and i just wanted to see this in real life. wow thank you

[NickDonnetelli]

An exchange of velocities demo gets across info. very fast. Thanks

[sahin]

he said "I am gonna let the higher one first", but professor, you should let them at the same time to make them meet in the middle, you know there is no relationship between height and frequency. They both have the same frequency (the only problem is air friction, which is not that important)

[HimanshuLyrify]

Velocity get interchange in each collision when mass are same

내가 궁금했던 것을 2분 만에 다 보여주시네 역시 외국 영상이 최고야

[ashokkumarsaxena]

It is beautiful
Thanks for sharing sir

[FiremanTO]

I think I deserve the credits for this class, along with being marked down for attendance even though I already graduated.

[NyanCoder]

I wanted to see if you swing them both in one direction but the side one much further

[daringaru]

What will happen if object is movie east to west and collide with object whose moving in North to South direction

[theBomified]

Now what would happen if one was rotating clockwise and the other counter clockwise?

[biplabkrsaha]

Nice demo sir, plz make such more video es ....it is very helpful for the students 🙏

[AdilKhan-kbyi]

I enjoy this video
Very interesting
Thanks

[PinoyBowlerGS]

Interesting video. Also you could find a lot of Bowling Balls at Pro Shops in Most Bowling centers but you can’t get them immediately cause Pro Shop guys requires you to have your ball drilled before buying it.

sir-"as in elastic collisions, mechanical energy is not transformed into some other form of energy like sound or thermal energy". But in above shown example we can see sound is coming after collision. Can we see it as a violation for the above fact????

[victormaxwellpeters]

Dear Professor,
But what about the velocity of sound then???
Even though there is elastic collision the velocity of sound remains constant how this is possible if it's not possible in case of two colliding elastic ball
