Conservation of angular Momentum
Introduction : In earlier topic we have seen about angular momentum which is rotational analogous of linear momentum. As linear momentum is conserved when external force acting on a system is zero , in the same way angular momentum is conserved if external torque acting on the system is zero.
Mathematically ,
L = r x p
