Physics Coursework Aim To investigate how high a tennis ball will bounce back after it has been dropped from a certain height How a Tennis Ball Bounces As the ball is elevated the ball gains gravitational potential energy equal to the ball's weight multiplied by its change in height1. When the ball is dropped, the height decreases, and therefore so does the gravitational potential energy. At the same time, the velocity of the ball increases due to gravity, and therefore the kinetic energy increases, as kinetic energy half the mass of the object (in this case the falling ball) multiplied by velocity squared (Source: Physics for You GCSE textbook). When the ball hits the floor the kinetic energy goes into deforming the ball from its original round shape to a squashed, oval shape. A tennis ball contains a rubber shell, which is filled with compressed gas. The ball is most stable in a round...
