Vedclass · Answer

(C) In the rotational motion of a rigid body about a fixed axis,every particle of the body performs circular motion.For any particle at a distance $r$ from the axis of rotation,the linear velocity $v$ is given by $v = r\omega$,where $\omega$ is the angular velocity.Since the body is rigid,all particles rotate by the same angle in the same time interval,meaning they all share the same angular velocity $\omega$.However,because the distance $r$ from the axis of rotation varies for different particles,the linear velocity $v = r\omega$ will be different for each particle.Therefore,all particles move with different linear velocities but the same angular velocity.

In the rotational motion of a rigid body,all particles move with:
