When a body moves in a circle, the angle between its linear velocity and angular velocity is always
Correct answer: C. 90⁰
- A. 180⁰
- B. 0⁰
- C. 90⁰
- D. 45⁰The angle between linear velocity (\( v \)) and angular velocity (\( \omega \)) for a body moving in a circle is always 90°. This is because linear velocity is tangential to the circle, while angular velocity is directed along the axis of rotation.
Explanation
The angle between linear velocity (\( v \)) and angular velocity (\( \omega \)) for a body moving in a circle is always 90°. This is because linear velocity is tangential to the circle, while angular velocity is directed along the axis of rotation.

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.
