  2. Rules of Slopestyle Skiing • In slopestyle skiing, there is a combination of grind rails and other terrain park obstacles, as well as large jumps. • The object of slopestyle skiing is to go down the course and try to perform the best trick possible on each obstacle. • Each skier receives a score from the judges based on their run. Each skier gets two runs, but only the highest score is kept. • Judges look for execution (how well they perform the tricks), amplitude (how much air they get off the jumps), variety, difficulty, progression, and combinations. • Five judges score each out of the two runs on a scale of 1 to 100.

  3. Slopestyle Skiing Jump Physics Diagram The skier’s velocity allows him to launch off of the jump and fly through the air. Gravity is pulling down on the skier causing him to fall to the Earth. The skier spins their body on the takeoff creating torque, thus making him rotate in the air. The low friction between the snow and the skis allow the skier to rapidly accelerate off of the jump.

  4. Slopestyle Skiing Rail Physics Diagram The skier’s velocity and inertia allow him to travel down the rail. There is friction with the skis and the rail. Gravity is pulling down on the skier keeping him on the rail.

  5. Physics Involved with Slopestyle Skiing Newton’s Laws of Motion • An object a rest tends to stay at rest, and an object in motion tends to stay a motion unless acted upon by an unbalanced force. A skier’s inertia allows them to launch off of the jump without coming to a stop once they ascend up the jump. • Force = Mass x Acceleration The greater the mass of a skier, the more force they need to push down on the snow with to lift off of the tip of the jump and accelerate forward. • For every action there is an equal and opposite reaction. A skier exerts a force on every grind rail that they grind on, and the rail exerts a force back on them. Other Physics Connections • Kinetic Energy- When a skier is going down the run, they have kinetic energy because they are in motion and doing different movements. • Potential Energy- When a skier is at the top of the run waiting to start downward, they have potential energy because their energy is stored.

  6. How can Physics be used to Improve this Sport? • Physics could be used to improve this sport if the course designers created larger jumps or used steeper slopes, so the skiers would have more air time, allowing them to do more complex and advanced tricks. This would allow physics to benefit the athletes. • Also, if they made more smooth skis with less friction, athletes would be able to gain more speed for the jumps, and rails, enabling them to perform more difficult tricks and get a higher score. • If skis had sharper edges, skiers could dig their edges into the snow and twist to create even more torque to rotate in the air. • Lastly, if people compose grind rails out of different materials that don’t rust or deteriorate , skiers would always be grinding on a slick, even surface, so they would be more consistent.
