Center of Mass

It’s the single point that represents the central average point of a skier’s body mass.  If a person’s body were completely rigid, it would be the point at which that body could be balanced on the head of a pin.  Any and all forces acting on a skier can be recognized by their individual and combined affect on the skiers Center of Mass point.  That point can be moved about the body, depending on a skier flexes and bends.

In skiing, a skier moves their Center of Mass through a skill called angulation.  By angulating and moving their Center of Mass, they can move or maintain their balance point however they want.  It’s how a skier determines how much weight they assign to their inside or outside ski, or to the front or back of their skis.
