As we all know the Winter Olympics are rapidly approaching, so I would like to do my entry about the physics of curling. Awhile back we learned about friction is the resistance that one surface or object encounters when moving over another. And as I understand the object of curling is to get your stone to the center, and knocking other people stones out of the way. There are also sweepers that go in front of the stone to smooth the ice to make the stone go faster. This involves friction. The more they brush the less friction they are creating. They use friction to place the stone where they want it.
