The area of force vs displacement graph gives _.

The area under a force vs displacement graph gives the work done.

Here's the step by step explanation:

1. The force vs displacement graph is a way to visualize how the force acting on an object changes as the object moves. The force is plotted on the y-axis and the displacement (or distance moved) is plotted on the y-axis.

2. The area under the graph (between the graph and the x-axis) represents the work done on the object. This is because work is defined as the force applied to an object times the distance the object moves (Work = Force x Distance).

3. So, when you calculate the area under the graph, you're essentially multiplying the force (height of the graph) by the displacement (width of the graph) at every point along the graph. This gives you the total work done on the object.
