Write the formula for power and angular momentum in rotational motion.

(N/A) In rotational motion, the power $(P)$ delivered by a torque $(\tau)$ to a rotating body with angular velocity $(\omega)$ is given by the formula:
$P = \tau \cdot \omega$
Where:
$P$ is the power in Watts $(W)$,
$\tau$ is the torque in Newton-meters $(N \cdot m)$,
$\omega$ is the angular velocity in radians per second $(rad/s)$.
The angular momentum $(L)$ of a rigid body rotating about a fixed axis with moment of inertia $(I)$ and angular velocity $(\omega)$ is given by the formula:
$L = I \cdot \omega$
Where:
$L$ is the angular momentum in kilogram-meters squared per second $(kg \cdot m^2/s)$,
$I$ is the moment of inertia in kilogram-meters squared $(kg \cdot m^2)$,
$\omega$ is the angular velocity in radians per second $(rad/s)$.
