Lecture 2: Motion

Lenny complained, “George, this jumpy stroboscopic stuff makes me nervous. Is time really so bumpy? I wish things would go a little more smoothly.”

George thought for a moment, wiping the blackboard. “Okay, Lenny, today let’s study systems that do change smoothly.”

Mathematical Interlude: Differential Calculus

In this book we will mostly be dealing with how various quantities change with time. Most of classical mechanics deals with things that change smoothly—continuously is the mathematical term—as time changes continuously. Dynamical laws that update a state will have to involve such continuous changes of time, unlike the stroboscopic changes of the first lecture. Thus we will be interested in functions of the independent ...
