Motion OF COM

The motion of the centre of mass is the result of

The motion of the centre of mass of a system of two particles is unaffected by their internal forces.

Two particles of masses m and 3m approach each other with different velocities. After collision, the particle of mass m has velocity vec( v) in their centre of mass frame. Velocity of particle of mass 3m in the centre of mass frame is

List-I shows some arrangements in which motion of masses are described and list-II defines motion of centre of mass of the system (m + M). Match appropriate possible options in list-II

The motion of centre of mass depends upon the total

Assertion : If there is no external torque on a body about its centre of mass, then the velocity of the centre of mass remains constant. Reason : The linear momentum of an isolated system remains constant.
