The angular velocity of a rigid body about any point of that body is same :

The angular momentum of a rigid body is

The angular velocity of particle of rigid body is not constant.

Define angular momentum of a rigid body.

Assertion : The angular velocity of a rigid body in motion is defined for the whole body Reason : All points on a rigid body performing pure rotational motion are having same angular velocity.

A : When a rigid body rotates about any fixed axis, then all the particles of it move in circles of different radii but with same angular velocity. R : In rigid body relative position of particles are fixed.

A : When a rigid body rotates about any fixed axis, then all the particles of it move in circles of different radii but with same angular velocity. R : In rigid body relative position of particles are fixed.

If the angular velocity of a rotating rigid body is increased then its moment of inertia about that axis
