# Video Lectures for Physics 121

## San Francisco State University

These lectures are video files that show the lecture I normally would presented in class, with audio accompanyment. You can view them at any time you wish, not just class time. You may also pause and go back.

A .pdf version of each lecture can also be found on the class website under: Lecture Notes
In addition to each video lecture, some links to videos are also included. These videos relate to the content of the lecture, and should be watched. Most of them simulate fun demonstrations that I would have done in class.
