Which term best describes the amount of work done or energy transferred when a force causes displacement?

Work is the amount of energy transferred when a force moves an object through a distance. The unit for this energy transfer is the joule, defined as the work done by a one-newton force acting over one meter of displacement (1 J = 1 N·m). In other words, when a force causes displacement in the direction of the force, the energy transferred is measured in joules. The other units represent different quantities: a newton measures force, a pascal measures pressure, and a coulomb measures electric charge. If the force isn’t aligned with the displacement, you use W = F d cos(theta), but when the force is along the path, it simplifies to W = F d.
