Mechanical power is the rate with respect to time at which work is done:
$$P=\frac{W}{\Delta t}$$
where,
P— mechanical power;
W— work done;
Δt— time.
Mechanical power generated by a force F on a body moving at the velocity v can be expressed as:
$$P=F \cdot v$$
where,
F— force applied;
v— velocity.
In the International System of Units (SI), the unit of power is watt (W), which is equal to one joule per second.
