The science of this sport
When you twist in air your creating something called angular momentumn which is created when torque is applied to a mass or in this case a skier. Have you ever wondered how skiers control their motion once in air. Here's how. They control their motion by controlling their moment of inertia which they do by moving their legs in and out.
This sport was first played at the 1988 Calgary Games. It became an official medal sport in 1992 in Albertsville.
