Question

if the body is moving in a circle of radius r with a constant speed v it angular velocity is​

Answer 1

Answer:

Radial Acceleration

If a body is moving around a circle, even if it is moving at a constant speed it is accelerating. This is because it is changing direction (it isn't moving in a straight line). The direction of this acceleration is towards the centre of the circle and the magnitude is given by: a = v2/r.

Answer 2

Dear Student,

◆ Answer -

w = v/r

● Explanation -

Suppose -

w = angular velocity in UCM

v = linear velocity in UCM

r = radius of circle in UCM

Then linear velocity in uniform circular motion is given by -

v = r × w

Rearranging this eqn,

w = v/r

Hence, angular velocity in uniform circular motion is​ v/r.

Thanks dear for asking. Hope this is helpful to you...
