Researchers in China have isolated the effects of electronic friction, showing for the first time how the subtle drag force ...

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 ...

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 ...

The phenomenon of friction, when studied on a nanoscale, is more complex than previously thought. When friction occurs, an object does not simply slide its surface over that of another, it also makes ...

If you want to know how to make a sneaker with better traction, just ask a snake. That's the theory driving new research by an expert who is studying snake skin to help engineers improve the design of ...
