In a closed, isolated system of particles, forces internal to the system do not change the motion of the system as a whole. The velocity of the center of mass of such a system is unchanged unless the system is impacted by some net external force. In this context, and with the aid of a single illustration, explain what is meant by a) internal force, and b) external force. c) Explain why internal forces have no effect on the system’s motion.

Consider three particles that interact with internal forces given by ? ⃗ 1→2, ? ⃗ 3→1, etc. The total force on the system is the sum of these internal forces with any external forces (? ⃗ i,ext , ?ℎ??? ? = 1,2,3). By writing out the sum explicitly, use Newton’s third law to prove that the total acceleration of the system is only due to the external forces.
