Work is a scientific concept that expresses the mathematical relationship between the amount of force needed to move an object and how far it moves. For work to be done, a force must be applied for a distance in the same direction as the motion. An object that does not move has no work done on it, even if forces are being applied.
Energy provides the ability to do work and can exist in many forms.
Work is the process of making objects move through the application of force.
