For my physics coursework, I have been asked to investigate the factors which affect the way in which a squash ball will bounce. I looked into a few different factors, including; Heat of the ball, landing surface of the ball, and in depth: the height from which the ball is dropped.

To observe how the height a ball is dropped from affects the height the ball bounces back to, we put a meter stick against a wall, with another one directly above it (two meters tall). We then held the ball so the bottom of it aligned with the height we were planning to drop it from (.80 m, 1.00 m, etc) and released it. Meanwhile, another member of our team was lying on the floor facing the meter stick, and observed, from ground level, how high the ball rebounded.

We dropped the ball at .2 m intervals between 0.6 and 2.0 m...
