Let's begin with a few exercises. I'll give you a force, and you must compute the potential energy due to that force.
Do you notice some patterns? It turns out that some forces -- we call them conservative forces -- have nice properties.
Let's look at conservative forces more closely ....
Now, see if you can use these relationships to compute some gravitational forces, based on a map of potential energy.
