In this video, I put gravity and friction to the test with a simple classroom experiment. When I tilt the table, you'll ...

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 ...

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 ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I ...

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 ...

Friction is a force that resists the motion of one object against another. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Scientists began ...

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 ...

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 ...

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 ...

A good sweater is like a cozy hug made out of yarn. For that, you can thank friction. A new study reveals how knit fabrics can take on versatile shapes that allow them to conform to the contours of a ...
