The angle between linear and angular velocity is
Correct answer: A. 90°
- A. 90°
- B. 180°
- C. 0°
- D. 45°
Explanation
The angle between linear velocity and angular velocity is always 90°. Linear velocity is tangential to the circular path, while angular velocity is perpendicular to the plane of rotation. Therefore, the angle between them is always 90°

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.
