... Newton’s Third Law – The Third Law of Motion: If body A exerts a force on body B, then body B exerts a force, equal in magnitude, but opposite in direction, on body A, i.e.., FAB = FBA, where FAB is the force exerted on body B by body A and FBA is the force exerted on body A by body B. This law is ...
