Question

V. Answer the following questions in detail: 1. Under what conditions a body can be rotated? Give one way to change the direction rotation of the body. Give the suitable example to support your answer.​

Answer 1

Answer:

A body rotates when there is a net torque acting on it.Change the direction of rotation of a rotating body with fixed axis we will have to provide a retarding torque which will ultimately stop the rotation and will start in the opposite direction.As a result the direction of rotation of the body will change.But if the axis is not fixed then the direction of rotation may be reversed simply by reversing the axis of rotation
