A problem gives a graph of force versus displacement for a particle. To determine the work done by the force, you should calculate:
Athe slope of the graph
Bthe area under the graph
Cthe intercept on the displacement axis
Dthe maximum value of force only
Answer & Solution
Correct answer: B. the area under the graph
For a force-displacement graph, work done equals $\int F\,dx$, which is geometrically the area under the curve. The slope gives how force changes with displacement, not the work itself.
