One of our favorite sections of FearOfPhysics.com (which has loads of great physics lessons) is their “Visual Physics” page, which contains two dozen fascinating interactive demonstrations you can play with.
How far does it take to stop your vehicle on a dry road / wet road / icy road?
How do we hear?
Why don’t satellites fall?
What is the science behind making a jump shot in basketball?

There’s lots more on the site. These are great fun, and all the physics behind the questions are fully explained.
