Squash Ball Bounce

Squash Ball Bounce

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

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
