The angular displacement of an object after one complete revolution is:
Correct answer: C. 2π radian
- A. 0 radian
- B. π radian
- C. 2π radian
- D. (1 /3) x π radian
Explanation
S= r x θ2pi x r =r x θθ = 2pi The definition of angular displacement is the angle traversed by the body in the circular arc. If the body completes a full rotation, it travels 2 pie radians of angle, but if you say its linear displacement, it will be zero as it rests at the same point where it started.

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.
