Energy and its Conservation
... The change in the potential energy depends on the height, but we have not said anything about where the height is measured from. As long as we talk only about differences in potential energy, the question doesn’t come up. When we want to talk about the actual amount of potential energy, we need to m ...

Work and Machines - MrDanielASBSukMSSci
... The amount of work performed on an object can be determined by multiplying force times distance. Work = Force x Distance The SI unit of work is the Joule (J or N x m) Power is the rate at which work gets completed or the amount of work done on an object in a given amount of time. Power = work / time ...
