 * THE STUDY OF AIR PRESSURE IN A BASKETBALL**


 * ABSTRACT**

The purpose of this experiment was to find out how the amount of air pressure affects how many times a basketball bounces. Inelastic and elastic collisions are what happens with the kinetic energy when there is a collision between two objects. Different amounts of air were pumped into a woman’s size basketball. The ball was dropped and the amounts of bounces were recorded. It was then found that for every 10 pumps of air that was added to the ball, the ball bounced 2 more times. This happened because of inelastic collisions, the harder the ball, the less kinetic energy that was lost in the collision.

One things that could be changes to improve the experiment is to check the amount of air in the ball at the end of class and at the beginning of class the next day, to check and make sure in did not loss air at night. Another thing to improve the experiment is to make sure that the ball is pumped with the same amount of air ever pumps. The pumps should be completely completed and go from the top of the pump to the bottom of the pump. In the future, an experiment that could be done is to see how the climate affects how many times a basketball bounces. Another experiment that could be done in the future is to see if you fill the basketball with different air type, would change the amount of pressure when the ball is dribbled.
