Skiing: It’s All About Friction

glide2It’s all about friction. Really. Friction from the snow, friction from the air, friction from the surface of the ski or the clothing you wear.  The physics of skiing is all about how to overcome drag and resistance and allow a skier to slice his/her way down the mountain.  And if Newton’s laws have anything to do with it, a skier who controls friction best has the best chance of winning.

Find out the basics of friction and skiing.

Aerodynamics and Cycling

Cycling has undergone immense changes since its early days.  As science has opened our understanding of aerodynamics, it has driven changes in bicycle composition and design, the clothing worn by the cyclist, and even the positioning of the rider on the bicycle.

These three factors directly correlate to the amount of drag experienced by the cyclist.  In fact, researcher L. Brownlie reported that some styles of baggy clothes cost cyclists 1.17% of their finishing time in a 100-meter race.  Serious cyclists utilize this knowledge by dressing in sleek, close-fitting clothing to optimize their aerodynamics.

How much of a role do aerodynamics play? Learn the basics or read the more technical explanation.
