The Nature of Force
... Do Action-Reaction Forces Cancel? Newton’s third law refers to forces on two different objects. Example: Soccerball If one player hits the ball – force is upward. The ball exerts an equal but opposite downward force on the player. The action and reaction forces are acting on different objects a ...
