Question

why is the workdme on an object mornig whit umitorm cirular motion zero ​

Answer 1

Answer:

W= Force is the direction of displacement x Displacement, or in simple words,

W= F X W X cos θ, where θ is the angle between direction of force and displacement.

In the case of Uniform Circular motion, there is only one force acting on the object, i.e. centripetal force, (this force acts towards the centre of the circular path of the object).

The motion of the object is tangential, therefore θ-90°; cos 90° =0

So, W=0
