The Physics Classroom is a multimedia tutorial website aimed at high school physics students.
Unfortunately, physics is often awkwardly taught (too many teachers mistake silence for comprehension), so it is important to have resources to learn concepts interactively at an individual pace.
The Physics Classroom is an interesting website directed at high school physics students. It's pretty basic, but covers typical high school physics curriculum. The site is divided into 3 areas: tutorials explaining core principles, a multimedia "studio", and a help area that covers basic classroom skills such as using a graphing calculator.
This is a good site to use as a supplement if you are a student and are feeling a bit lost in class.
