Newton's

Third Law of Motion

"For every action, there is an equal and opposite reaction."

Newton realized that forces always come in pairs. These pairs of forces are equal to each other in sizebut opposite in direction. He called the forces "action and reaction".

Action (one direction) = Reaction (opposite direction)
