If an object is not acted upon, it will tend to maintain its current state, which corresponds to the angular velocity being constant.



The phenomenon is called inertia and gives rise to Newton's first principle in its version for rotation and generalizes the idea by defining that objects tend to keep the angular momentum constant which in the case of the moment of constant inertia is reduced to constant angular velocity.



The principle also leads to the fact that if the moment of inertia varies and the angular momentum is constant, the angular velocity will also be reversed.
