Enter initial height h_i above the ground at which ball is thrown or dropped. Define upwards to be positive. Please enter only positive values for height as heights are all measured above (upwards from) the ground. Then enter initial velocity u of ball. If you are throwing the ball upwards, enter a positive u, if throwing the ball downwards, enter a negative u, if dropping the ball from rest, enter 0 for u. During each bounce, the ball may lose energy (e.g. in the form of sound or heat), so the total energy may decrease after each bounce. You can select the percentage of energy loss during each bounce using the slider below. You can select 0 (no energy lost) as well. Assume there is no air resistance. Mass of the object is taken to be 1kg.
