The work done on an object is directly proportional to the force on the object, the displacement of the object, and the cosine of the angle between the force and the displacement:

W = Fd cos 0

Energy is the ability to do work.

Work is a scalar quantity, which is usually measured in newton-meters or joules.

Work is 0 when the force is perpendicular to an object's displacement or when the object isn’t displaced.
