A rigid body is rotating about an axis. The best way to stop it is applying

A rigid body is rotating about an axis. To stop the rotation, we have to apply

A rigid body is rotating about a vertical axis. In t second, the axis gradually becomes horizontal. But the rigid body continues to make v rotations per second throughout the time interval of 1 second. If the moment of inertia I of the body about the axis of rotation can he taken as constant, then the torque acting on the body is

A rigid body is rotating about a vertical axis at n rotations per minute, If the axis slowly becomes horizontal in t seconds and the body keeps on rotating at n rotations per minute then the torque acting on the body will be, if the moment of inertia of the body about axis of rotation is I.

A rigid body is rotating about fix axis. P and Q are its particles. Which of the following physical quantity is same for P and Q?

A rigid body is free to rotate about an axis. Can the body have non-zero angulalr acceleration of an instant when its angular velocity is zero?

A rigid body is free to rotate about an axis. Can the body have non-zero angulalr acceleration of an instant when its angular velocity is zero?

Define moment of inerita of a rigid body capable of rotation about an axis. State its physical significance.

The moment of inertia of a rigid body is not unique , about a given axis. The moment of inertia of a rigid depends on axis about which it has to be calculated.
