And let me graph a potential s of t right over here. We have a horizontal axis as the time axis. And let me just graph something. I'll draw it kind of parabola looking. Although I could have done it general, but just to make things a little bit simpler for me. So I'll draw it kind of parabola looking. So that is, if we call this a y-axis, we could even call this y equals s of t as a reasonable way to graph our position as a function of time function.
