The angular momentum of a system of particles is conserved

Kinetic Energy and Angular Momentum of a particle

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.

Angular momentum of a body is the product of

Show that the angular momentum about any point of a single particle moving with constant velocity remains constant throughout the motion.

Show that the angular momentum about any point of a single particle moving with constant velocity remains constant throughout the motion. Is there any external torque on the particle ?

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 :
