Write the change in magnitude and direction of angular velocity with respect to time of a rotating body about a fixed axis.

The direction of the angular velocity vector is along

What is direction of angular velocity for a rigid body?

Derive the equation of angular momentum in the case of rotational motion about a fixed axis.

Which forces needed for the rotational motion about a fixed axis?

Write the formula of work done by torque in rotational rigid body about a the fixed axis.

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

How many degrees of freedom does a rotational motion about fixed axis?

A vector has both magnitude and direaction . Does it mean that anything that has magnitude and direction is necessarily a vector ? The rotation of a body can be specified by the direction of the axis of rotation , and the angle of rotation about the axis . Does that make any rotation a vector ?

A particle is moving with constant speed v along the line y = a in positive x -direction. Find magnitude of its angular velocity about orgine when its position makes an angle theta with x-axis.
