Squash ball experiment
Aim:
My aim is to investigate what effect temperature has on the resulting bounce on a squash ball.
Variables:
. There are many variables to consider, such as
2. Pressure of air inside the squash ball
3. Type of surface the squash ball is bounced on
4. Height the squash ball is dropped from
5. Temperature of the squash ball
6. Material of the squash ball
7. Mass of the squash ball
8. Angle of surface that the squash ball is bounced on
9. Air resistance
0. Diameter of the squash ball
1. Temperature of surface that that squash ball is bounced on
2. Room temperature
Prediction
Through my scientific knowledge of the collision theory, I predict that as I increase the temperature of the ball, the bounce of the ball will increase as well. This is because as the ball gets hotter the particles in the ball gain energy and collide more. This means that when the ball hits the ground the particles collide so much that the ball is bounced higher. Therefore when I decrease the temperature of the ball the particles don't have as much energy so there is bounce but not as high. Also the ball is made from rubber, and rubber is very flexible so it will deform for a fraction of a second. As it is a solid, it will return to its original shape when the atoms return to their original shape.
The ball gains its most gravitational potential energy, when it is held at the set height. This turns to kinetic energy when the ball hits the chosen surface. This will occur until the energy is fully distributed by either kinetic or gravitational potential energy.
