No...
When a body is rotating, or free to rotate, around an axis, a torque must be applied to change its angular momentum. The amount of torque needed to cause any given angular acceleration (the rate of change in angular velocity) is proportional to the moment of inertia of the body.

Moment of inertia shows the tendency of an object to stay in its state of rotatory motion. If an object has more mass, then it is more difficult to rotate it. ... Thus, moment of inertia depends upon mass. Consider the two identical objects of the same mass at different distances from the axis of rotation.
