Vedclass · Answer

(A) In uniform circular motion,an object moves along a circular path with a constant speed.Since speed is the magnitude of velocity,the magnitude of velocity remains constant.However,the direction of velocity is always tangent to the circular path at any given point.As the object moves,the direction of the tangent changes continuously.Therefore,the velocity vector,which includes both magnitude and direction,is not constant.Thus,only statement $(i)$ is correct.

In uniform circular motion:
$(i)$ The magnitude of velocity is constant.
$(ii)$ The velocity vector is constant.
$(iii)$ The direction of velocity is constant.
Select the correct statement.
