Physics Coursework:Bouncing a squash ball

... Physics Coursework: Bouncing a squash ball It is well know amongst squash players that the ball becomes more bouncy when it has been struck against the wall many times. There are a number of possible reasons for this. It might be that hitting the ball against the wall flexes the rubber and alters it in some way to make it more elastic but the most probable reason is that the violence of the collision heats up the ball and it changes in temperature, which is the most important factor in determining how bouncy the ball is. The investigation is to find out how temperature of a squash ball affects its bounciness. The first thing that I want to get straight is, what is meant by bounciness? Well at first I thought that bounciness was changed by how high the ball was dropped from. But then as I thought about it, I realised
