The direction of linear velocity of a body moving in a circle is
Correct answer: A. along the axis
- A. along the axis
- B. along tangent
- C. directed towards center
- D. directed away from center
Explanation
he linear velocity of a body moving in a circle is always directed along the tangent to the circle at the point where the body is located. This is because the linear velocity is perpendicular to the radius at any given instant.

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.
