 | Before you assign flipped videos from which you expect your students to learn, you need to teach them How to Learn from a Flipping Educational Video! |

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
