» Mechanical power

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.

Mechanical Power FAQ

What is mechanical power?
Mechanical power is the rate at which work is done or energy is transferred.

What is the formula for mechanical power?
Mechanical power is P = W / delta t, and for motion under force it can also be written as P = F x v.
