The moving object gains kinetic energy when it bounces, and loses potential energy as it falls. Newton's third law states that every force or action has an equal and opposite reaction. Hence when a force is applied to a surface, it also applies a force equal in magnitude, but in the opposite direction.
TLDR; Big O'le anime tiddies like mine are governed by the laws of Newtons third law, Buoyancy physics, and ofc some insane mass. (huehuehuehue)
