have to write a 2-3 page report about geometry in skiing... already have ski dimensions, turning radius and vertical drop, any other ideas?

rotations in tricks, angle/ shape of jumps (how tall, what angle, how much of a lip), the consequences of landing on flat ground vs. an incline.

Your body's center of gravity when it spins, the spinning of a 360 has to be level circle and not a wobbly one, sliding a flat bar versus a round bar (surface area contact), surface area contact of skinny skis versus fat skis and why powder skis need to be fat, tip height/angles.

could talk about camber and rocker and different types of skis like that...lots of possibilities there

Lot's of park crews today use math to figure out where to place and how to form jumps in the parks. You could use that as an example.

That is more physics with normal forces and trajectory, which does rely on geometry, but also involves some heavy calculations. I would stick to your basic rotations and trigonometry considering the whole mountain is a slope. In my physics class last semester we had to do a set of "real life" physics problems. Using some simple calculus, I estimated tanner's speed that he hit chads gap at, and how much faster he and his ankles would have had to have been going to clear it. Showed the video too, aced that shit.

vectors relating to the angle of your body going down the hill and how your speed can increase with different vectors. kind of a physics thing but it could work
