**Power Output** refers to a mathematical representation of average power. In other words, to calculate average power, one should use the following equation, where power equals work divided by time:

- $ P = \frac{W}{t}\, $

In mechanics, the work done on an object is related to the forces acting on it by

- $ W = F \cdot \Delta s \, $

where

*F*is force- Δ
*s*is the displacement of the object. One can more easily understand this equation for human power output by multiplying force (weight moved) by distance (displacement) and dividing that by the total time.
