牛頓第一運動定律-慣性定律

In episode six of the Shedding Light on Motion series, presenter Spiro Liacos is hrown forward?in a head-on collision, hrown backwards?when his tram takes off, and hrown 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 a number of different forces that affect our lives daily.
