Linear Momentum Of Two System Of Particle Relative To Centre Of Mass Frame

Kinetic Energy Of Two Particle System Relative To Centre Of Mass Frame

Work Energy Theorem Relative To Centre Of Mass Frame

The rate of change of angular momentum of a system of particles about the centre of mass is equal to the sum of external torque about the centre of mass when the centre of mass is :

Total linear momentum of a system of particles is equal to ……………..of the system and velocity of ……… .

Consider the following two statements: A. Linear momentum of a system of partcles is zero. B. Kinetic energ of a system of particles is zero.

Show that the total linear momentum of a system of particles is conserved in the absence of any external force. Also show that total linear momentum of the system is equal to the product of the total mass of the system and the velocity of its centre of mass.
