What you will not find on my site is any attempt by me to write my own physics textbook or content reference material. That would be a silly use of my time considering how many great ones are out there already. Below are some links to some of my favorite online resources. I also have a ridiculous number of physics textbooks in my classroom of different levels of depth, organization, and applied mathematics. If you want to borrow one, let me know. While I do not use a textbook in my classes, I do assign readings from various sources. Having access to a textbook can be beneficial if you wish to look up a physics topic with reliable explanation and example applications.
The Physics Classroom -- the site has great reference materials, practice problems and interactive simulations.
Hyperphysics -- a concept map of all physics topics. Dive deep and you will get to specifics with examples and calculators.
Learn AP Physics -- I am no fan of AP tests, but this site has some good instructional videos and problems.
Flipping Physics -- great physics videos.
CK-12 Interactive Physics for High School -- excellent online flexbook with embedded video, interactive lessons and checks for understanding.
