... The basic unit of work is the joule(J) and is equal to the product of one newton and one meter. In the English system of measurement, the unit of work is the foot pound, the product of a force of one pound acting through a distance of one foot. In order for work to be done, there must be a force ac ...

... We’ve talked about kinetic energy, which is energy of motion - if something isn’t moving, it has no kinetic energy. We defined energy as the ability to do work and saw that we could change the kinetic energy of an object by doing work on it. Potential energy can be thought of as energy of position, ...
