As you all know, rubber balls (tennis balls) do not bounce good if there are holes in them. Why is that? I have 2 ideas as to what it is but i'm not sure which one. 1. The rubber cannot compress properly so the ability for the rubber to store elastic energy is gone. 2. The air inside of the ball usually provides constructive interference when the ball bounces back up. If the air can't compress, it can't provide that constructive interference. 1 makes a lot of sense but I've been golf balls with huge cuts in them work perfectly fine. Thoughts?
