Mechanical power

Mechanical power is the rate with respect to time at which work is done:

$$P=\frac{W}{\Delta t}$$


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:

$$P=F \cdot v$$


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.
