In a rock tumbler, the stones collide with each other and break apart. Eventually they become smooth. I was thinking about exchange of energy like when billiard balls hit. When two billiard balls collide, they exchange their energy. It's a little different if they have different amounts of momentum. This makes me question how a rock tumbler works. Can someone explain what is it about rock tumbling that causes the rocks to break up when they collide?
