Without the force called friction, cars would skid off the roadway, humans couldn't stride down the sidewalk, and objects would tumble off your kitchen counter and onto the floor. Even so, how ...

Explore the physics behind a penny on a spinning record player and the role of friction! 🌀💡 In this video, we break down the forces acting on the penny, explain how friction affects motion, and ...

While friction isn’t the only influence on the slopes, it is definitely something at the top of a skier’s mind—especially ...

Here’s the rub with friction — scientists don’t really know how it works. Although humans have been harnessing its power since rubbing two sticks together to build the first fire, the physics of ...

Researchers in China have isolated the effects of electronic friction, showing for the first time how the subtle drag force ...

A model system has been presented by researchers that allows the investigation of atomic-scale friction effects and friction dynamics that are similar to those taking place, for instance, in proteins, ...

This article has been updated to include comments from Raymond Goldstein and Patrick Warren. It is a mathematical puzzle that stumped Galileo, but researchers in France think they have discovered how ...

Dumping literal tons of hot volcanic material down a lab flume may finally have revealed how searing mixtures of hot gas and rock travel so far from volcanic eruptions. These pyroclastic flows can ...

I learned to respect friction, as a phenomenon with many nuances, when I was a graduate student. One day, while teaching a problem session in elementary mechanics, I unwisely invented a new problem to ...
