Physics: Squash Ball Coursework
It has been observed that squash players seem to warm there ball up before a game, and it seems to affect the bounce.
Variables
There are several factors which will effect the bounce of the ball, They are:
* The height that the ball is dropped from.
* The temperature of the ball.
* The mass of the ball.
* The force at which the ball is thrown with.
* The surface of the ball (if it is hard or soft)
The factor I am going to look at will be the temperature of the ball when it is dropped.
The variables that I will not change are
* The height that the ball will be dropped from,
* The ball I will use and
* The surface the ball is dropped on.
I will use all the same equipment. The only thing I will change is the temperature of the water, and in turn the ball
Equipment list:
* 1 squash ball
* 1 clamp stand
* 1 table
* 2 meter sticks
* 1 heat mat
* 1 tripod
* 1 gauze
* 1 beaker
* 100cm³ of water
* 1 thermometer
* 1 pair of tongs
* Several paper towels

Preliminary work
Before I conducted my experiment I carried out some preliminary work. The aims of this work were to find a suitable height for me to drop the ball from and to decide what temperatures I would use when heating the ball.
I heated up a beaker with 100ml of water in it. I also had a squash ball in the beaker. I heated it up to 50°C, when the ball was at the right temperature, I dropped the ball from 2 meters. A person was lying on the floor with their head level to where they predicted the ball would bounce. This person recorded the height of the bounce. I put the ball back into the beaker and heated the water up to 60°C, 70°C, 80°C and 90°C. and repeated the experiment
