Most people have experienced the hair-raising effect of rubbing a balloon on their head or the subtle spark caused by dragging socked feet across the carpet. Although these experiences are common, a ...

A research team led by CU Boulder has designed a new kind of synthetic “skin” as slippery as the scales of a snake. The research, published recently in the American Chemical Society journal Applied ...

1.1 What is friction? Take this everyday example: when a coffee mug rests on a flat table, the kinetic frictional force is zero. There is no force trying to move the mug across the table, so there is ...
