the physics of competitive skiing



The goal of competitve skiing is to cross the finish line the fastest, while navigating tight turns and obstacles throughout the run. The skier, during the course, minimizes the resistance to motion in order to maximize their speed, both from air resistance and snow resistance. In minimizing their air resistance, they reduce their projected frontal area. This is showed when the skier is in a crouched position, resulting in a lower drag force. Minimizing the drag force is done by two factors; body posture and the choice of race suit. Also the mass of the skier can help lower the drag force. The more mass a skier has, the greater force of gravity acting upon the skier results in a smaller magnitude of the drag force. Here, the skier will reach a greater velocity.
