Khan Academy is running a Talent Search for people who are exceptionally good at teaching through videos. The contest runs through June 21st. So, if you create such videos, please apply!
Thank you so much to David Santo Pietro, without whom I would not have known about this contest and therefore would not have applied. Thanks David!
I made a mistake in one of my recent videos. It is so subtle it took almost 7000 views before someone noticed and let me know, however, it is still a mistake. Therefore, I have fixed the mistake and this video replaces the previous version. I guarantee you I have made mistakes while teaching in the classroom which went unnoticed. This is what I love about posting all of my lectures to YouTube, my mistakes will be noticed and I can fix them.
Please, if you have a link to my previous AP Physics 1: Simple Harmonic Motion Review, please update that link. FYI: The mistake was, in the words of Mario Penaloza, whom I thank both for noticing and letting me know about the mistake, "If position #1 is already to the right then the graph you showed for velocity is wrong because the derivative of cos(x) (position) is -sin(x) not sin(x) … Let me know if I'm wrong.” That’s correct, I forgot a negative sign, that is all it was. However, it made the velocity graph incorrect, which is unacceptable. Here are some of the great YouTube comments I received during the first fortnight of May. Also, I just passed the 400,000 view mark, which is nice.
If you are taking an AP Physics C exam this Monday, you certainly should utilize my review and exam solution videos. Oh, and Enjoy the Exam!

Yep, I make physics videos in the hope that you can learn physics. If you are a physics teacher, I am very hopeful that you will want to use them to help flip your physics class. Archives
