I am one of four passionate physics teachers at Webster Groves High School in St. Louis, MO. I teach AP Physics 1 and 2, but I teach calculus with the class as well, since physics makes no sense without it. I use Walker's excellent textbook, Physics 2nd Edition. My videos are organized into playlists for each chapter of that book, and really should be watched sequentially if you have the time.

I try to align my class with a firstyear physics class at top universities. You may find the videos useful for tutoring and review. Please do problems immediately after watching a video. This is how you will become a stronger physicist.

Some people have been asking to support my work with beer. Money can be more easily sent, so please feel free to send me some at the GoFundMe page link below. I'll be very grateful if you do my dog pooped in my wife's new handbag. Also, let me know if a video is particularly unhelpful I will redo it when I have time.
