An isolated system consists of N objects undergoing collisions with each other. Describe the motion of the center of mass of the system.(1 point) Responses The velocity of the center of mass of the system changes slightly with each collision. The velocity of the center of mass of the system changes slightly with each collision. The center of mass of the system remains stationary until the first collision, then changes velocity slightly with each collision. The center of mass of the system remains stationary until the first collision, then changes velocity slightly with each collision. The velocity of the center of mass of the system does not change even as collisions occur. The velocity of the center of mass of the system does not change even as collisions occur. The center of mass of the system moves randomly as collisions occur. The center of mass of the system moves randomly as collisions occur.

In an isolated system, the total momentum is conserved. Therefore, the motion of the center of mass of the system remains unaffected by the internal collisions of the objects within it.

The correct response is: The velocity of the center of mass of the system does not change even as collisions occur.

This is because, while the individual velocities of the objects may change due to collisions, the overall motion of the center of mass remains constant unless acted upon by an external force.
