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

In Newton's Third Law, 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 they're fired? How do our muscles work? What propels us when we're swimming? How exactly is gravity a two-way interaction? All these questions will be answered in this excellent program.
