Action-Reaction Pair: This term refers to the two forces that are part of Newton's Third Law. One force is called the action force and the other is called the reaction force.
Momentum: Momentum is a property of moving objects and is directly related to their mass and velocity. According to Newton's Third Law, when two objects interact, their momentum changes in opposite directions but with equal magnitudes.
Conservation Laws: Conservation laws state that certain properties (such as momentum) remain constant in a closed system unless acted upon by external forces. Newton's Third Law plays a role in conservation laws by ensuring that momentum is conserved during interactions between objects.
