The rate of change of the total momentum of a system of particles is equal to the sum of the external forces on the system. But, by Newton's third law of motion, Fji+Fij=0, so the theorem is proved. ... If the sum of the external forces on a system is zero, the linear momentum is constant.

Answer 2

Answer:

Theorem: The rate of change of the total momentum of a system of particles is equal to the sum of the external forces on the system. But, by Newton's third law of motion, Fji+Fij=0, so the theorem is proved. ... If the sum of the external forces on a system is zero, the linear momentum is constant.
