Detailed explanation-1: -According to Newton’s third law, “for every action there is an equal and opposite reaction". When we hit the ball on ground then in this case there is an equal and opposite force on the ball in the upward direction due to ground(Newton’s Third Law), which makes it bounce.
Detailed explanation-2: -This is because some of the original kinetic energy has been transformed into sound, fric-tion, and deformation of the ball. A ball dropping is an example of an inelastic collision where part of the kinetic energy is changed to some other form when colliding with a surface.
Detailed explanation-3: -The ball exerts an equal and opposite force on the racket. This is the reaction force. Newton’s third law explains how many sports injuries are caused. The more force you use to a hit a tennis ball, the more reaction force your arm receives from the racket.
