Real physics education. Learn with Billy, Bobby, and Bo. New videos pretty much weekly. Currently working my way through the AP Physics 1 curriculum. Please visit FlippingPhysics.com for lecture notes, video playlists, and more! Did you know I teach part-time to allow time to make these Flipping Physics videos? That's because it takes a tremendous amount of time to make videos of this quality. That means I make 40% of the money a full-time teacher does. Can you imagine that? So realize, yes, I provide of the videos for free. This is because there are many people on this planet who cannot afford high-quality education like this. However, if you can afford to, especially if you are assigning my videos for students to learn from, please pledge me a few dollars a month on Patreon. If not, there are other ways to help out as well. Thanks. - Mr.p, Billy, Bobby, Bo.
