Question

Quizplus · Accepted Answer

This statement is a restatement of Newton's first law of inertia, which states that an object at rest will stay at rest, and an object in motion will stay in motion with a constant velocity, unless acted upon by an external force. In the case of rotational motion, the object will maintain a constant angular velocity (i.e. constant speed of rotation) unless acted upon by an external torque, which is analogous to an external force in linear motion.
