Newton’s second law of motion for rotating bodies states that the rate of change of angular momentum of body is equal to total torque acting on the body.
When net torque on the body is zero then the angular moment of the body remains constant. This is also known as the conservation of momentum.
The variation of angular velocity $\left(\omega \right)$ is shown as,
$I\omega$ = constant
where
I = moment of inertia
$\omega$ = angular velocity
