"For every action, there is an equal and opposite reaction."
Newton's statement implies that in every interaction, there is a pair of forces acting on the two interacting systems. The size of the forces on the first system equals the size of the force on the second system. The direction of the force on the first system is opposite to the direction of the force on the second system. Forces always come in pairs - equal and opposite action-reaction force pairs.
