Oct 22, 2007 The height to which a ball bounces depends on several factors: 1) The height from which it is dropped, 2) Whether it was thrown down or just dropped and how hard it was thrown, 3) How much energy is lost in the ball during the collision with the floor 4) How much energy is lost in the floor during the collision with the ball
