Abstract: It is a bird, no its a plane, no it is a ski jumper. Flying through the sky like a bird the jumper gloriously glides in the air at very high speeds in order to go as far as possible. In reality, ski jumping involves a lot of science. Many physics concepts can be seen during Ski Jumping. In the long ski jump concepts such as gravity, friction, projectile motion, KE/PE and air resistance are present. Also, physics of a plane wing are involved in modern ski jumping. To understand the process of ski jumping first the jumper converts his potential energy into kinetic energy by going down the ramp, then flying off in the air and falling in a projectile motion but while in the air creating a v shape to capture air resistance like a plane wing in order to fly longer. And finally, if everything went as planned landing safely on the ground.

This paper has been really interesting to read! I had never thought of aerodynamics in the way you described with shrinking your body's surface area, and now that I think about it, it does make sense thinking about it that way! I was also surprised that skiers go as fast as 60 miles per hour! I never knew that skiers could use their skis like plane wings to maintain flight that's Awesome!
ReplyDeleteThank you Oleg for your insight on the physics in ski jumping. The many ways of the physics laws in the sport creates an understanding for me now. I did not know ski jumping having a difference in the aerodynamic world.
ReplyDeleteThis presentation was really informative. There are so many physical concepts in ski jumping. That is insane! This presentation made it easier for me to understand the physics behind ski jumping.
