Quizplus · Accepted Answer

The principle of conservation of momentum during a collision is derived from Newton's second law (force equals mass times acceleration) and Newton's third law (for every action, there is an equal and opposite reaction). These laws together imply that the total momentum of a closed system remains constant if no external forces act on it.
