The dynamics of the tectonic faults that produce earthquakes remain puzzling. An inference from laboratory experiments could help: at high rates of slip, friction at the interface may fall ...

(Nanowerk News) Working together to study friction on the atomic scale, researchers at UC Merced and the University of Pennsylvania have conducted the first atomic-scale experiments and simulations of ...

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 ...

A suspended apparatus used to minimize friction during the experiment. The heavier brass cylinder and lighter ping-pong ball collide repeatedly against the transparent wall, reproducing 31 collisions ...

Wear has major impacts on everything from the bearing of a wind power plant to an artificial hip joint. However, the exact cause of wear is still unclear. Scientists now show that the effect occurs at ...

Physicists should “think big” when it comes to calculating the effects of friction on tiny nanomachines, according to researchers in the US, who say that they have strong evidence against the widely ...
