as everyone probably knows, there is a ton of physics involved in snowboarding. when one rides a snowboard down a hill, you can get going pretty fast. this is because of the very low coefficient of friction between a waxed board and snow (right around .05). the coefficient of friction is determined by 2 things: the nature of the surfaces, and the force of gravity aka your weight. since the 2 surfaces are very smooth, there aren't a lot of bumps to cause friction which can really allow for a lot of speed. another way physics is involved with snowboarding is when you go down a steeper hill, you go alot faster because the force of gravity is more direct.
