Write the formula for power in the motion of a rigid body.

(N/A) For a rigid body rotating about a fixed axis,the power $P$ delivered by a torque $\tau$ is given by the product of the torque and the angular velocity $\omega$ of the body.
Mathematically,the formula is expressed as:
$P = \tau \omega$
Where:
$P$ is the instantaneous power,
$\tau$ is the torque applied to the body,
$\omega$ is the angular velocity of the body.
