Work Done by a Variable Force #8211; If the magnitude of a force is varying with the time, then we have to introduce the method of integration to determine the work done by the force from the initial position as a lower limit to the final position as a higher limit. W = ʃ F . d r The net work done by number of forces is equal to sum of work done by individual forces.
