Question

Which of the following is the correct SI unit for angular acceleration?
Options
A m/s²
B rad/s
C rad/s²
Correct Answer
D m²/s
Correct Answer

Option C is the correct answer.

Detailed Explanation

Angular acceleration (α) is the rate of change of angular velocity. Angular velocity is in rad/s, so the rate of change of angular velocity has units of (rad/s)/s = rad/s².

Hint

Angular acceleration measures how quickly angular speed changes. Its units are the units of angular speed divided by time.
