Alpine Skiing

Alpine Skiing is a sport where participants on skis, race down a snow covered hill whilst weaving in and out of gates to cross the finish line with the fastest time.

Canadian Participants:-Manual Osbourne-Paradis-Eric Guay-George Simmerling-Kerrin Lee-Gartner-Brigitte Acton-Sochi 2014 Bronze medalist Jan Hudec

Simple Machines: Skis and ski poles. Both act as 3rd class levers. Forces: Forces in this sport include gravity, mechanical forces (muscular force/pushing with legs) and G forces.Effects of Air resistance, friction and gravity: A skier uses wax to lessen the friction between the skis and the ground, and a body suit to cut down on air resistance so gravity can pull you down the hill faster

Equipement includes ski poles, ski helmates, ski boots, body suit, and skis

Why Fail?

This fail is considered a fail for a few reasons:- She had a poor landing from a jump resulting in balance issues.-Because of a loss of balance, her center of gravity came over here base resulting her to flip and slide down the course.-As well as the fact that one of her skies did not release from her boot like it was made to do (This is to provide less injury to the wearer).




Epic Fail
