Question

Dynamics of rotational motion about a fixed axis

Answer 1

Explanation:

Since rotation here is about a fixed axis, every particle constituting the rigid body behaves to be rotating around a fixed axis. ... A particle in rotational motion moves with an angular velocity. Moment of inertia and torque for the rotational motion are like mass and force in translational motion.
