Question

define uniform circular motion and also write expression for angular displacement.
​

Answer 1

Answer:

when when a body is moving in a circular path around a fixed point. The motion is known as uniform circular motion if the velocity is constant or uniform

Answer 2

Explanation:

Uniform circular motion” is the kind of motion of an object in a circle at a constant speed. With uniform circular motion, as an object moves in a particular circle, the direction of it is constantly changing. Herein, in all instances, the object is moving tangent to the circle.

Angular Displacement (Δθ) = (ΔS/r)

Where Δ’s refers to the linear displacement while r is the radius. Radian is the unit of Angular Displacement.
