The unit of angular acceleration is
Correct answer: C. Radian per second2
- A. Radian
- B. Radian per second
- C. Radian per second2
- D. None
Explanation
Angular acceleration (α) is the rate of change of angular velocity (ω) with respect to time (t):The formula for angular acceleration is given by:α= Δω/ ΔtThe SI unit of angular acceleration is radians per second squared (rad/s2).

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.
