Which of the following statements is the best rotational analogue of the linear statement “An object moves with constant velocity if no net external force acts on it”?
(a) An object maintains constant angular acceleration if the net external torque is zero.
(b) An object maintains constant angular momentum if the net external torque is zero.
(c) An object maintains constant angular velocity if the net external torque is zero.
(d) An object maintains constant angular velocity if no net external force acts on it.
