  • Make physics education fun and real.
  • Provide free lecture videos for teachers to help flip their students' learning.

Communication of the week:

  • 2019.05.19: "Mr. P, you never cease to amaze me. I started watching your videos as a sophomore when I took Honors Physics 1. Your videos helped me score a 5 on the AP Physics 1 exam. You made me love and enjoy physics so much that I decided to take the AP exam without taking the class. Next year, I will be taking AP Physics C as a senior. I cannot wait to continue my physics journey with you. ❤️" lovejilly7 - YouTube Comment
Did you know I teach part-time to allow time to make these Flipping Physics videos? That is because it takes a tremendous amount of time to make videos of high caliber. Yep, I am in the classroom 40% of the time of a full-time teacher. That means I make 40% of the salary a full-time teacher. Can you imagine that? So realize, yes, I provide all 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.
