Snowboard Motion & The Center of Gravity

The Center of Gravity is the mean location of the gravitational force acting on a body.  When standing still, the center of gravity can be viewed as an imaginary line down the middle of the body, where your weight is equally distributed on each side of the line. 

In order to balance on a stationary snowboard, your center of gravity must be directly over the center of the snowboard.  The cool thing about snowboarding is you can "cheat" gravity by using momentum.  As you progress and move faster, the more you can lay your body out and appear to be on the brink of falling.  The key is to be able to move your board back under you in time so you don't fall.  Once you get the hang of it, the motion you create is a feeling like no other.
