The direction of linear velocity of a body moving in a circle is _.
Correct answer: D. Along the tangent
- A. Along the radius away from the centre
- B. Along the radius towards the centre
- C. Changing with motion
- D. Along the tangent
Explanation
Linear velocity is also called tangential velocity as its direction is always tangent to the point at which the object is placed on the circle. Hence Option D is correct.

About Angular and Linear Quantities
Rotational motion relates angular displacement, angular velocity and angular acceleration to linear displacement, tangential velocity and tangential acceleration through the radius. Questions use radians, v equals r omega and tangential acceleration, while distinguishing tangential velocity from centripetal acceleration and angular quantities from their linear counterparts.
