Energy transformation in a bouncing ball Planning Aim To investigate the energy transformation in a bouncing ball. When a ball is held above the ground it possesses Gravitational Potential Energy (GPE). When it falls down, because of the force of gravity, it loses Gravitational Potential Energy but gains Kinetic Energy and some loses by heat. This tells us that 'Energy cannot be created or destroyed but can only change from one form to another'. Now I am going to find out what proportion of the energy is lost during a bounce and to see if there is a pattern. Prediction After the ball bounces, it gains elastic energy, with this energy, it moves upward and gain Kinetic energy which is converted into GPE until the ball reaches the top of its bounce whereupon the whole process is repeated. But each time when the ball bounces, some of the energy is lost by heat and...
