Gliding down the mountain
The laws of Physics cant be broken, but they can be bent. Take friction, for example, friction is the rubbing of two objects against each other when one or both are moving. one way you can relate that to is rubbing your hands together. Try rubbing your hands when they are pact down tightly, then rub them together when they are touching, but with little force, then move your hands in thin air, not touching anything, as you probably know, it was harder to run your hands across each other when they are pressed tightly together than when they are barely touching, and not touching at all. Now, try this when your hands are wet, just run them over the faucet, you dont have to drown them, just get them wet. You will notice that it is alot easier to move your hands when they are wet than when they are dry. This is the same as when you step onto a snowboard or skis, when your board goes onto the snow, it takes the water out of the snow, and puts it onto the board, and gets packed down. that's what makes the pure powder into hard packed racing snow. Friction plays a small role in the physics of snowboarding, but it does play a role in everything.
