Magnitude of velocity is constant but direction changes

Vedclass · Answer

(D) Since the car covers equal angles in equal intervals of time,its angular velocity $\omega$ is constant.Given the relation between linear velocity $v$ and angular velocity $\omega$ is $v = r\omega$,where $r$ is the radius of the circular path.Since both $r$ and $\omega$ are constant,the magnitude of the linear velocity $v$ remains constant.However,in circular motion,the direction of the velocity vector is always tangent to the path at any point,which changes continuously.Therefore,the magnitude of the velocity is constant,but its direction changes.

$A$ car moves on a circular road. It describes equal angles about the centre in equal intervals of time. Which of the following statements about the velocity of the car is true?
