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 ...

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 ...
