The Physics of Skiing

physics of skiingLast month I made a connection between intermediate skiing and geometry.  This applies to advanced skiers and to take it a step further, I’ll add physics to the mix.

There are two ways to put your skis on edge. The first method, inclination, uses the whole body. Angulation, the second method, creates angles by using our hips and knees joints.

When skiing at speed we can tip our whole body relying on centrifugal force to hold us up. These banked type turns can be fun in a cruising type mode but will not allow for very good edge hold as the edge angle created can only be as large as the amount of body tip.

Skiing The Mad River Valley… With Help

I don’t really know much about skiing in Vermont. I know that the Green Mountain spine produces magic snow out of thin air, and the farther north you go, the greater the magic. But my ability to find the best skiing anywhere outside of New York is limited.

Champlain Bridge

That’s not to say that I haven’t had some great times skiing on the other side of Lake Champlain. It seems every time I’ve made the trip, the combination of magic snow and great guides have made my ski days great.

My most recent trip into Vermont was into the Mad River Valley — over the lake, across the farmland and through the gauntlet — the App Gap.
