Which quantity is a scalar quantity?
Correct answer: D. None of these
- A. Angular displacement
- B. Angular velocity
- C. Angular acceleration
- D. None of these
Explanation
Displacement, velocity and acceleration are vector quantities as they have magnitude and direction associated with them.

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.
