Potential Energy (PE) = mass x gravity x height This gives the potential energy at the height when the ball is held at the start of the test. This can be used as a check to for the Kinetic energy (KE) equation as the law of energy conversation states that energy may neither be created nor destroyed. Therefore the sum of all the energies in the system is a constant. So the PE when the ball is held at height will be the same as the KE just before the impact with the glass.
