Bouncy Ball Experiment
Bouncy Ball Experiment
Aim:
The aim of this experiment is to investigate the efficiency of a bouncing ball, and the factors which affect its efficiency.
Prediction
I predict that the higher I drop the ball from the higher it will rebound up, because it will have more gravitational potential energy the higher dropped from. As it is dropped the ball will have kinetic energy, and then when it hits the ground changes to heat and sound energy, and kinetic as it rebounds back up. The higher up the ball is dropped from the more gravitational potential, more kinetic energy on the way down and therefore more sound heat and kinetic energy when hitting the ground. The ball will bounce higher the higher dropped from as the energy has to go somewhere! The ball's efficiency (what fraction of the energy the ball has left after being dropped), will when dropped from a small height i.e. 25cm, be a high percentage, because air resistance won't affect the ball. As the height dropped from......
