Physics is all around us, even in skiing! For example, there is friction between the ski is and the surface of the snow due to gravity pushing down on the skier. When starting from rest, the skier accelerates down the slope as a result of gravity. There is air resistance known as drag which slows the skier's velocity. This is extra clothing which is exchanged for a slim suit which is worn by racers. I can't wait to ski this winter and be able to apply all of the physics to my favorite activity.
