Finding Work from Force-Displacement Graph
In a Force-Displacement graph, work done is equal to the area in between the graph and the horizontal axis.
The graph above shows the force acting on a trolley of 5 kg mass over a distance of 10 m. Find the work done by the force to move the trolley.
In a Force-Displacement graph, work done is equal to the area below the graph. Therefore, work done
W= 1 2 (10)(8)
W = 40Nm
W = 40J
