Does a body rotating about a fixed axis have to be perfectly rigid for all points on the body to have the same angular velocity and the same angular acceleration ?Explain.

A body moves with constant angular velocity on a circle. Magnitude of angular acceleration

When a body is moving with a constant angular velocity , its angular acceleration is…………………………………. .

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.

Consider the following two statements A and B and identify the correct choice A) When a rigid body is rotating about its own axis, at a given instant all particles of body posses same angular velocity. B) When a rigid body is rotating about its own axis, the linear velocity of a particle is directly proportional to its perpendicular distance from axis

A body rotates about a fixed axis with an angular acceleration of 3 rad//s^(2) The angle rotated by it during the time when its angular velocity increases frm 10 rad/s to 20 rad/s (in radian) is

Two points of a rigid body are moving as shown. The angular velocity of the body is : .

A rigid body rotating about a fixed axis with uniform angular retardation completes 33 rotations before its angular velocity is reduced to half of its initial value.Find the number of rotations made by the body further before it comes to rest.

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

Moment of inertia of rigid body is equal to _______ the rotational kinetic energy of the body rotating with unit angular velocity about the given axis.
