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 ...

Scientists developed a new model, which shows that rubbing two objects together produces static electricity, or triboelectricity, by bending the tiny protrusions on the surface of materials. Most ...

I've been thinking a lot about the role of friction lately -- or perhaps more importantly, the lack thereof -- in media design. Generally speaking, the user experience design of our most successful ...

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 ...
