Asked in NUMS 2021 2021Moderate
An object moving along a circular path of radius 1m. It covers a distance of 2m along the circumference of the circle. What will be the angular displacement covered by it?
Correct answer: B. 2 radian
- A. 1/2 radian
- B. 2 radian
- C. 3 radian
- D. 2/3 radian
Explanation
Angular Displacement =s/r s=2 and r=1 so angular displacement = 2

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.
