For a rigid body in equilibrium, linear acceleration of its centre of mass is _______ and the angular acceleration of the body is _______

When a body is in equilibrium, its acceleration is

The angular momentum of a rigid body is

A body starting from rest gains an angular speed of 540 r.p.m in 6 second. The angular acceleration of the body is

If a body is moving with a uniform speed v in a circle of radius 'r', then the angular acceleration of the body will be

The potential energy of a body mass m is U=ax+by the magnitude of acceleration of the body will be-

Explain angular acceleration .Establish its relation with linear acceleration.

A body of mass 5 kg is attached to a weightless string wound round a cylinder of mass 8 kg and radius 0.3 m. The body is allowed to fall. Calculate (i) tension in the string (ii) acceleration with which the body falls and (iii) the angular acceleration of the cylinder.

Define angular acceleration. Deduce its relation with linear acceleration.
