Lesson 38: Graphing Work Like many other concepts in physics, it is often easier to interpret information or come to conclusions if the data is presented as a graph. This does sometimes make it harder when you are first learning physics, since we make you learn a bunch of rules for each type of graph. You should try to see beyond the rules… if you can do this, and understand each graph for what it truly represents, you will be on the road to understanding physics. In the case of Work, the graph that we are most interested in is Force vs. Displacement and the area underneath (or sometimes above) the line. Imagine a really boring situation where a constant force is applied to an object that causes it to move a displacement. The graph would look something like. .. If you were asked to calculate the area under the line of the graph, what would you do? Since it is a rectangular shape, you’d probably say Area = base X height But wait a second… the base is a displacement and the height is a force…
