What are some demonstrations of Newton's Third Law of Motion?


Quick Answer

A common example of Newton's Third Law of Motion is found in swimming. As force is exerted against the water with the movement of an arm or leg, it creates an equal, opposite reaction against the swimmer by the water propelling him forward.

Other examples include air passing over an airplane's wing. The action of the air being deflected downward by the shape of the wing creates a reaction of an upward pressure against the wing itself. The energy that presses up against the wing and causes aircraft to be able to stay aloft is called lift. Jet engines also create an example of the Third Law of Motion when the engine produces thrust, the force created in reaction to the action of the turbines spinning at high speeds.
