It’s no wonder earthquakes are so difficult to predict. Even simple laboratory simulations of the friction breakdowns that send tectonic plates lurching into motion are maddeningly difficult to ...

Because of friction, sleds don't technically touch the snow and instead ride on a small layer of water created by the heat of the sled sliding down the hill. Sledding is one of many ways Wisconsinites ...

Forgive me for all the posts on ESPN's Sport Science (example: Pulling and Power). I can't help myself. In the short episode recently, Sport Science compared a football player pulling a sled with huge ...

It was once a game of luck using misshapen stones from Scotland’s riverbeds first thought to be played out on frozen waters in the mid-16th Century. In the four-and-a-half centuries since, a sport ...

Curling is a thrilling sport filled with strategy, skill, sweeping, surprise and science! Curling is a mesmerizing sport filled with strategy, skill, surprise, a lot of yelling, and science—yes ...

Rougher surfaces cause more friction. For an object to move, there must be a force upon it - this is usually a push or a pull. As the object starts to move, another force occurs between the object and ...

Quick, out behind the bike shed, Professors Pendry and Leonhardt are having a fight over a completely hypothetical situation. If we hurry, we should catch the end of round three. Science: it is ...

Scientists at Purdue University have made the fastest spinning object ever, a tiny ball of silicon dioxide that rotates 300 billion times per second. They positioned the microscopic silica balls in a ...

Introduction Have you ever driven up a mountain, seen a sign reading "Hazard! Icy Roads Ahead," and wondered why ice makes roads dangerous to drive on? The answer has to do with friction—specifically, ...
