Question

If an object moves a circular distance s of radius r, then what is its angular displacement?

Answer 1

Dear student

The angular displacement is defined as the angle through which an object moves on a circular path.
It is the angle (radians) between the initial and final positions.

(θ_f - θ_i) = angular displacement

θ = s/r

θ = angular displacement through which movement has occurred

s = distance travelled

r = radius of the circle
