 It is a property of a distribution of mass in space that measures its resistance to rotational acceleration about an axis. Newton’s first law, which describes the inertia of a body in linear motion, can be extended to the inertia of a body rotating about an axis using the moment of inertia. That is, an object that is rotating at constant angular velocity will remain rotating unless acted upon by an external torque.
