... Work, Energy and Power are scalar quantities. Let’s review the definitions: Work done on an object by a constant force is W = (F cosΘ)s, where F is the magnitude of the force, s the magnitude of the displacement and Θ the angle between the force and the displacement. The unit of work is Nm = J (Joul ...
