The SI 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 Velocity
Angular velocity describes how quickly angular displacement changes with time, with ω = Δθ/Δt and units of radians per second. Questions relate angular and linear motion through v = rω, use the direction given by the right hand rule, and distinguish angular velocity from angular acceleration and ordinary frequency.
