Okay, so I've got a question on graphs and areas under curves. For example, a force-distance graph, with force on the y-axis and distance on the x-axis, where you find work done from that graph. I understand that a constant force will produce a horizontal line on the graph, like so: Force | |------------- | | |___________distance So the area under the line is just force x distance. This matches the equation, work = force x distance. But I'm having trouble understanding a proportional graph, or one that looks like a triangle, like this: Force |------/----- |-----/----- |----/------ |---/------- |--/-------- |-/--------- |/_________distance i.e. force increases at a constant rate. To find work done from this, you find the area under the line, which is a triangle. But this doesn't match the equation (work = force x distance) which is confusing me. Why is it not force x distance like the equation? Why is is 1/2 force x distance now? I understand that this is because the area under the line is a triangle, but why is work done the area under the graph?
