By contrast, when inline skaters coast, their wheels are rolling, not slipping. Their wheels constantly grip the ground. Braking Ice skaters use their edges to stop - edges allow a much higher friction contact between the blades and the ice. Turning To turn a corner, ice skaters use their blade edges to dig into the ice. They push outward on the ice, and the ice pushes them into the turn.
Wheel skaters rely on friction between the blades and the street.
Wheels spin only forward, not sideways, so it's easy to push sideways. Otherwise, the physics of the turn is identical. I've been learing all sorts of tricks on ice this semester, but I haven't had time to try them out on concrete. The mowhawk turn, in which the skater rotates and steps backwards, I predict will be easier on concrete. But again, I haven't tried this yet.
