Work done by an external non-conservative force is equal to change in the mechanical energy of the system.Final M. E - Initial M. E = WIf an external force does no work, then mechanical energy will be...

It states that if net torque acting on an isolated system is zero, the angular momentum remains conserved. Since Torque is equal to the rate of change of angular momentum so when torque is zero, dL/dt=0 So,...
