The Physics Classroom

My teen is taking physics in high school this year, and is finding it a tough course. She says half the class is usually sound asleep and sometimes the teacher seems to be too, although his eyes are still open...

A once-a-week tutor may not be enough to get her through, so I figured I'd look online for some help, and there's a wonderful place called The Physics Classroom, which describes itself as "an online, free to use physics website developed primarily for beginning physics students and their teachers."

 I don't know anything about physics, so I looked what I thought I might have a chance at: the very first classroom tutorial in 1-D Kinematics. I clicked on the Introduction to Lesson 1 - Describing Motion with Words and (within a minute) was able to score 100% on the "Check Your Understanding" portion regarding vectors and scalars.

I could see this as being a great review site for exam or test time and a reference for when concepts or definitions aren't well understood.

While most of the site is text, there are animations that help explain concepts like acceleration. Try the first question on this page and (if you're like me, and you get it wrong), you'll understand how helpful the detailed answer is.
