When a ball bounces on the ground, the ball and the ground exert equal and opposite forces on each other. As the ball collides with the ground, the ground exerts an upward force on the ball, causing it to bounce back up into the air. At the same time, the ball exerts a downward force on the ground, leading to a deformation of the ground surface. This interaction between the ball and the ground is governed by Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction.
