This claim is trivially true by definition and everyday observation, as Newton's third law of motion dictates equal and opposite force pairs rather than elastic return to an original position.
The claim refers to introductory physics and Newton's third law, which states that forces always occur in equal and opposite pairs. Bouncing back to a starting point depends on energy conservation, elasticity, and restoring forces, not directly on the third law of motion. Because this is a basic matter of definitions and everyday physics observation, no citation is needed and the balance verdict is common knowledge.
