The Momentum of snowboarding

The momentum of snowboarding is the movement of the snowboarder. Momentum is an objects frequency to keep moving in the direction its going. Momentum is a result of a force, not a force itself. The main concept of momentum that relates to physics is linear momentum and angular momentum.

Linear Momentum in Snowboarding

Linear momentum in snowboarding is the force that keeps you going downhill. Linear momentum is always in the direction of the riders velocity. Linear momentum is easily found by multiplying the mass by the riders velocity. An example of linear momentum would be a weight difference in the riders. Gravity forces snowboarders downhill at the same velocity, but the mass of the riders does affect the total momentum. Both riders will finish with the same velocity they started at, but the heavier rider will finish first.  

Angular Momentum

Angular momentum is almost like linear torque. When a snowboarder plans to do multiple spins after leaving the jump, he must build up as much angular velocity before doing so. Some things snowboarders do to maximize their angular velocity is tucking their arms in and just about twisting their body the opposite way before leaving the jump. This will give them the right momentum to spin fast enough in the right amount of time. The closer you can pull yourself to your own center of gravity, the faster you will spin. However, in order to keep spinning, snowboarder will throw their arms in the direction they're spinning to almost lead their bodies to continue in that direction.
