Action and Reaction•Newton’s third law describes something else that happens when one object exerts a force on another object. 33Newton’s Third LawNewton’s Third Law•According to Newton’s third law of motion, forces always act in equal but opposite pairs.
Action and Reaction•Another way of saying this is for every action, there is an equal but opposite reaction. 33Newton’s Third LawNewton’s Third Law•This means that when you push on a wall, the wall pushes back on you with a force equal in strength to the force you exerted.
Action and Reaction Forces Don’t Cancel•The forces exerted by two objects on each other are often called and action-reaction force pair. 33Newton’s Third LawNewton’s Third Law•Either force can be considered the action force or the reaction force. •Action and reaction force pairs don’t cancel because they act on different objects.
•You constantly use action-reaction force pairs as you move about.
