Unfortunately, this writeup doesn't mention any words like "spin" or "rotation" or "angular", not even to disclaim that those aspects are not presently being addressed. It looks like a great resource for kids in grade 11 or 12 physics.

Basically what he’s understood so far. “Expository webpages - For my own future reference.

- playingalong 2y agoChances are the author is in 11th or 12th grade. And you two might be on the same page. (Just joking).
- contravariant 2y agoSince it also doesn't mention friction I'm a bit confused what effect, if any, you were expecting to see. Dealing with friction complicates matters significantly. At the very least you can't expect the collision to be elastic.
- kazinator 2y agoActually, I believe that it can be elastic, if the friction is so great that the surfaces do not slip the entire time they are in contact.
- Jerrrrrrry 2y agotil how rubber bouncy balls work
- kazinator 2y agoYes. They can bounce back and forth due to the spin reversing. I believe each time they make contact with the floor, high friction causes of spent to stop, while they undergo a rotational deformation, which then reverses direction.
