This lecture starts a departure from what has become our standard practice of building upon what we’ve just finished. In a certain sense, we could say that we’ve been working on a novel so far in this course.  Well, the good news is that the novel is pretty much completed. What we will be working on now are going to be more like short stories in that the material will no longer be building higher and higher on what we’ve done so far.  Instead, we will be introducing some new definitions, and at times pulling out some old ideas or laws to help us with what we want to accomplish, but you should not be getting the feeling of a huge weight still building upon your shoulders.  The review material that we’ll be needing will be just a few major points (kinematics, Newton’s 2nd law, conservation of energy or momentum), but nothing overwhelming.

We’re heading into the homestretch for the remainder of the semester.  In the process, we’ll be talking about some interesting topics which will basically show us some cool things that are now  within our grasp.

We get started in this lecture with a discussion of the important topic of Springs, Pendula, Simple Harmonic Motion, and Resonance.
