For a small θ, angular displacement is quantity

In circular motion, if the angular velocity and angular acceleration becomes parallel, then the motion becomes:

A child riding on a large merry-go-round, travels a distance of 3000m in a circle of diameter 40m. The total angle through which child revolves is:

A body moves in a circle with increasing angular velocity. At time t= 6sec, the angular velocity is 27rad/s. What is the radius of circle made by the body where linear velocity is 81cm/s?

A particle of mass m is moving in a horizontal circle of radius R with a uniform speed. When it moves to a point diametrically opposite then

A particle of mass 2 kg is moving along a circular path of radius 1 m. if its angular speed is 2π rad s^–1, the centripetal force on it is:

In circular motion, the radius vector

The angular displacement covered by a body in the following graph is

A car is moving with high velocity when it has a turn. A force acts on it outwardly because of

All particles of a rigid body rotating about a fixed axis may not have same
