if some force is applied on the body and it covers some distance, then it is said to be in work.
formulae of work
W= F * S
if the force has a component in the same direction as the displacement of the object, the force is doing positive WORK. If the force has a component in the direction opposite to the displacement, the force is NEGATIVE then.
