Angular Displacement Formula

The angular displacement is the angle through which a body rotates in circular path. It is denoted by $\theta$ and expressed in radians or degrees.
Angular Displacement Formula
Angular Displacement Formula
Angular displacement formula is used to find the angular displacement $\theta$ made by the body in time t.
Angular displacement formula in terms of angular velocity is given by

Angular Displacement Problems

Back to Top
Here are some problems given on angular displacement based on the above formula.

Solved Examples

Question 1: A motor bike is moving in circular track covers the whole track of distance 50m having radius of 4m from the center. Find its angular displacement.
Solution:
 
Given: Linear displacement S = 50 m,
          Radius of circular path r = 4 m,
The angular displacement is given by
$\theta$ = $\frac{S}{r}$
= $\frac{50}{4}$
= 12.5 radians.
 

Question 2: A body is moving in a circular path with a angular speed of 59 rad/sec. Calculate its angular displacement at time t = 5 s?
Solution:
 
given: Angular speed $\omega$ = 59 rad/sec,
         Time t = 5 s
The angular displacement is given by
$\theta$ = $\omega$ t
= 59 $\times$ 5
= 295 radians.
