Frames of reference

Have you ever been resting in your friends parked car in a parking lot, not really paying attention, waiting for friends to come back with your coffee and you notice the car beside you move.  Your initial reaction is that you are moving.  That is a perfect example of frames of reference.  

The motion you see is based on how you look at it at or where you view the motion from.  I really can't explain it any better then how these two Professors did it back in 1960. I first saw this in high school and is excellent.

It is presented by Prof. Ivey and Prof. Hume of the University of Toronto.  

Well worth the 30 minutes it takes to watch!
