Math Counts In the Science of the Olympics

It might not be as obvious as physics or materials engineering, but math from arithmetic to calculus can describe every move the athletes make from jumps to spins on the snow and ice.

Math counts in the Olympics. There are 2,500 athletes competing in 86 sports and events to win 252 medals at the 2010 Vancouver Winter Olympics. But these are only the base numbers in the games.

Math is all around in scores and measurements, motion and quantities. It can be as easy as how many hockey players are on the ice? Or how many times has the puck gone into the net?

Scoring in ice skating involves arithmetic. Addition is only part of the scoring. Each element is assigned points and then is judged on how well it is performed. A triple axle is worth three points, but the judges will also rate the overall performance and artistry of the skater.

Nine judges give scores, but only five of the scores will count. Two of the scores are thrown out at random, then the highest and lowest

Science of Snowboarding in the Olympics

Believe it or not, snowboarding is a study in potential and kinetic energy.  The athletes who maximize both kinds of energy are the ones on the medal podium at the Vancouver Olympics.

Twelve years ago, snowboarding made its debut as an Olympic sport. The sport isn’t just about crazy lingo, going fast and jumping high. The athletes use the laws of gravity to build speed and keep their balance. They also use physics to gain speed and height in jumps.

The physics of snowboarding uses dynamic balance. When the snowboarder is in motion moving up and down the ramps, their balance is different than if they were just going down a slope.

As gravity pulls the snowboarders down the halfpipe, they gain speed. At the same time, they are being pushed against the sides by contact forces.

Snowboarders push back against the G-forces and build speed by pumping their legs up and down. By standing up against the extra forces in the curve, snowboarders add to their kinetic energy – the energy of motion. It gives them the speed
