Watch Shedding Light on the Physics of Motion - Newton's First Law

In this program host Spiro Liacos is "thrown forward" in a head-on collision, "thrown backwards" when his tram takes off, and "thrown to the side" when his car suddenly turns a corner. But in fact none of these things actually happen. Using excellent visuals, this program looks at the fact that an object will remain stationary or move with a constant velocity unless a force acts on it.
