Physics can definitely be displayed while snowboarding. You start with an initial velocity before going down the hill usually you start from rest, then you have a constant acceleration throughout your whole trip down the hill, and you also have a final velocity which is the velocity you end with. Also the distance you travel and the time you finish the distance in is just as important. All of these components play a large part in physics. Also momentum and impulse are involved in snowboarding if you crash into someone else either moving or if they are staying still.
