Researchers have demonstrated how to entirely suppress static friction between two surfaces. This means that even a minuscule force suffices to set objects in motion. Especially in micromechanical ...

Using high-speed photography and digital image correlation techniques, engineers show that friction along a faultline has a complex evolution during an earthquake that is dictated, in part, by slip ...

Now I get to do something with that force scale I built. I had a request some time ago to talk about friction. Friction is surprisingly complicated. When two surfaces rub against each other, why is ...

It may seem like fun and games, but understanding how dominoes topple isn’t child’s play. “It’s a problem that is so natural; everybody plays with dominoes,” says David Cantor, a researcher at ...

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 ...
