A system of particles is free from any external force `vec v and vec a` be the velocity and acceleration of the centre of mass, then it necessarily follows that :

A system of particles is acted upon by a constant nonzero external force. If v and a are instantaneous velocity and acceleration of the centre of mass, then it is possible that at a given instant

A system of particles is acted upon by a constant nonzero external force. If v and a are instantaneous velocity and acceleration of the centre of mass, then it is possible that at a given instant

Give an expression for the velocity and acceleration of the centre of mass of a system of particles.

If the total external forces on the system of particle is zero, then find the velocity and acceleration of its centre of mass.

A system of N particles is free from any extenal forces. (a) Which of the following is true for the magnitude of the total momentum of the system?

A system of N particles is free from any external forces Which of the following must be true for the sum of the magnitudes of the momenta of the individual particles in the system ?

Net external force acting on a system of particle is not equal to zero. If velocity and acceleration of the centre of mass of the system of particles at some instant of time are found to be v and a respectively select possible option (s).

Show that a system of particles moving under the influence of an external force, moves as if the force is applied at its centre of mass.

What will be the velocity of the centre of mass, when the total external force on the system is zero ?
