1. The problem statement, all variables and given/known data Why does a ball bounce less and less high, even though the force exerted by the ground on the ball is the same, due to Newton's third law. I do understand the ball loses energy as heat energy. 2. Relevant equations F=ma ; F1=-F2 3. The attempt at a solution I'm just curious why this happens. Thanks. I know the ball loses kinetic energy, and I know that the force initially applied on the ball determines the height of the bounce.
