Mechanical power is the rate with respect to time at which work is done:
$$P=\frac{W}{\Delta t}$$
where,
Pβ mechanical power;
Wβ work done;
Δtβ 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,
Fβ force applied;
vβ velocity.
In the International System of Units (SI), the unit of power is watt (W), which is equal to one joule per second.
Mechanical power is the rate at which work is done or energy is transferred.
Mechanical power is P = W / delta t, and for motion under force it can also be written as P = F x v.
