Question

why is centre of mass frame called zero momentum force ?

Answer 1

Hey, mate here is your answer✌✌》》

The previous equations show that the center of mass of a system of particles acts like a particle of mass M, and reacts like a particle when the system is exposed to external forces. They also show that when the net external force acting on the system is zero, the velocity of the center of mass will be constant.

Answer 2

momentum of a system from its centre of mass fram is zero because ,p=mv ,where v is the relative velocity of the centre of the mass of the system with respect to the reference frame and the velocity of the centre of mass with respect the centre of mass is zero ,so P=mv=m*0=0
