SUMMARY
Action-reaction force pairs arise as a fundamental principle of Newton's Third Law, which states that for every action, there is an equal and opposite reaction. This principle is not merely a consequence of electrostatic repulsion or energy conservation but is considered an axiom in classical mechanics. The discussion highlights that these force pairs can exist even without physical contact, such as in gravitational interactions between two bodies. Momentum conservation can also be used to derive these force pairs, but the concept of action and reaction is viewed as more foundational.
