Write the general formula of total angular momentum of rotational motion about a fixed axis.

(N/A) For a rigid body rotating about a fixed axis,the total angular momentum $L$ is given by the product of the moment of inertia $I$ of the body about that axis and its angular velocity $\omega$.
The formula is: $L = I \omega$
Where:
$L$ is the angular momentum,
$I$ is the moment of inertia about the axis of rotation,
$\omega$ is the angular velocity of the body.
