Ice Skating – A Classic Lesson in Physics

The Olympics may be over, but teachers and parents are still using the science behind the games to educate children.

Ice skating is a classic lesson in physics. When an ice skater spins, they are using angular momentum. In a spin, their arms act as weights. When arms are extended, the skater spins slowly. When the skater changes their moment of inertia and bring their arms into their body, they spin faster.

I brought this demonstration to Becky Ditchfield on the morning newscast. It’s my rule to never practice ahead of time with Becky. So, what you see on TV is the first time she’s ever seen the demo. I guess she’s sensitive to getting dizzy because she could barely read the teleprompter at the end of the segment. If I hadn’t of caught her, she would have spun into a half million dollar camera.
