Angular displacement is zero when?
Correct answer: A. angle =0
- A. angle =0
- B. v=0
- C. r=0
- D. both b and c
Explanation
Arc length (s) is found by the formula = S = radius x angular displacement,so, angular displacement = arc length / radius; it can only be zero when the angle is zero.

About Angular Displacement
Angular displacement measures the change in a body’s angular position and is expressed in radians or degrees, with anticlockwise and clockwise directions assigned signs. It connects to arc length, angular velocity and angular acceleration, and must be distinguished from ordinary linear displacement in rotational motion.
