Model the snowboard course to help you fly higher Abstract Snowboarding is the leading trend in todays world of sports, it not only requires athletes’ excellent skills, but the accurate and precise designing of the snowboarding are essential as well. Snowboarding for a good athlete, a good venue is in the race reached its maximum vertical vacated, and play an important guarantee optimum levels. To ensure the athletes will reach the maximum vertical air, we build a model of the snowboarding track. We first built a simple model, and then we redesigned and changed more detailed aspects of the model to optimize the model. Finally we came out with a safe and practical model project. Firstly, to find out the main factor affecting the Vertical air, we analyzed and studied the movement of the athletes on the U-shaped track, and concluded that the kinetic energy which an athlete needs during while vacating is transferred from gravity. According to this finding, we built a simple semi-circular cylinder. We found the friction and resistance were always the same and the whole movement consists of the movement along the boarding track and the movement perpendicular to the track, and established multiple differential equations. We gained the work done by resistance forces during these two processes. prepare between two actions, we built a circular smooth glide in the middle of the semi-circle, and this the U-shaped model is improved. Athletes in the slide area should keep a constant state of motion . According to the data we got from the previous model, we calculated the sliding velocity of the athlete at the bottom of the U-shaped track. We obtained the designing requirements for the bottom of the U-shaped track according to the reaction time of the athletes. The last step is to ensure that the athletes will be able to complete the rotation, flipping and other difficult movement, we use the world’s most skilled and difficult movement of Shoun White as an example to build app
