Another way of analyzing the work done by a force is to do a force-
displacement graph. The graph to the right is a plot of force vs.
displacement for a 30 N box being lifted 2.0 m. The shaded area under
the graph (Figure 1) equals the work input. (W=Fexde=30N x
2.0 m = 60 J) Since no machine was used to lift the box, the graph of
work output would be the same.
(Wo=F₂x d₂=30N x 2.0 m = 60J)
