Just as velocities may be integrated over time to obtain a total distance, by the , the total work along a path is similarly the time-integral of instantaneous power applied along the trajectory of the point of application. If a force of 10 newtons, for example, is applied over a distance of 3 meters, the work is equal to 30 newtons per meter (or 30 joules). To exert ones mental or physical powers, usually under difficulty and to the point of exhaustion to subject to or engage in forms of exertion in order to train, strengthen, or condition to have ones work cut out doing sth, to have ones work cut out to do sth ( n programm, das arbeitslose verpflichtet, eine tätigkeit oder ausbildung zu absolvieren, um weiterhin zahlungen zu empfangen ( ) ( ) () ( to get into, or put into, a stated condition or position, slowly and gradually.
Therefore, work on an object that is merely displaced in a conservative force field, without change in velocity or rotation, is equal to these formulas demonstrate that work is the energy associated with the action of a force, so work subsequently possesses the , and units, of energy.

If force is changing, or if the body is moving along a curved path, possibly rotating and not necessarily rigid, then only the path of the application point of the force is relevant for the work done, and only the component of the force parallel to the application point is doing work (positive work when in the same direction, and negative when in the opposite direction of the velocity).
