In episode six of the Shedding Light on Motion series, presenter 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 brilliant visuals, this episode looks at the fact that an object will remain stationary or move with a constant velocity unless a force acts on it. It also describes...

In episode eight of the Shedding Light on Motion series, we look at that most poetic of all Laws. For every action there is an equal and opposite reaction. How does a rocket engine work? Why do guns recoil when fired? How do our muscles work? What propels us when we're swimming? And how exactly is gravity a two-way interaction? All these questions, and many more, are answered in this excellent video.

Isaac Newton's three Laws of Motion are clearly described, using animation and video to illustrate each law at work. This video introduction to Newton's Laws combines creative animation with concise narration and a touch of humor. The program is designed to help viewers develop a basic understanding of each law and how it works in the real world. A number of key physical science terms are introduced and defined: motion, inertia, friction, force, mass,...

In section one of this program, colliding basketball players demonstrate the Principle of Conservation of Momentum, while section two debuts all three of Newton's Laws of Motion, as illustrated by moving a large bookcase, hanging from a rope, and pushing against a wall. Newtonian concepts of inertia, force, mass, weight, equilibrium, tension, and momentum, plus free-body diagramming, are also covered. "Live the laws, love the laws, be one with the...
