So many ways to play with Newton's balls...

I'm really liking these Second Thought vids.

Since I don't belong to any of those groups I get to lump them all together.
No stereotypes just a bunch of smartalecy whippersnappers who better stay off my lawn.

I made a Newton's Cradle years ago out of bowling balls.
It took a while to figure out why it didn't work.

I also made one but of the normal materials and scale. I made it in woodshop in a previous century. It's lost now though. Mine worked well, why didn't yours work DJ?

It is the equal masses of the balls in the cradle that allow for the uniform transfer of momentum and the neato patterns.
Bowling balls are all the same size but of different weights (mass) and. as a result, go helter-skelter.
I eventually put together a well-matched set and it did work, all the way up to eight balls.

Interesting that they are just over or under the density of water, hence some float and some sink.
Makes a good bar or swimming pool bet.

Little known fact, Saturn is also a duck.

Is this the "what are you drinking thread"?

BigV 05-06-2020 05:09 PM

no, it's the cryptopython thread

No shame in fear but it's to your advantage to fear the right things...
