work is the process of converting energy from one form to another. there are two necessary factors for doing work: the force acting on an object and the distance traveled by the object in the direction of the force. the definition of classical mechanics: when a force acts on an object and causes the object to pass a certain distance in the direction of the force, mechanics says that the force has done work on the object.

work done: w=fd

force: f=w/s

distance: s=w/f
