To see physics in action in everyday life, look no further than figure skating.
And as the men hit the ice to show off their spins and combinations Tuesday in the Winter Olympics, here’s a perfect chance to watch examples of basic scientific concepts, such as friction, momentum, and the law of equal and opposite reactions.
On one level, the difference between dancing on a floor and skating on ice is the lack of friction. Smooth ice provides very little resistance against objects, like ice skates, being dragged across its surface. Compared to, say, a wooden floor, ice has much less friction.
