Researchers in China have isolated the effects of electronic friction, showing for the first time how the subtle drag force it imparts at sliding interfaces can be controlled. They demonstrate that it ...

A team of microsystems engineers at Université de Lyon, École Centrale de Lyon has developed a method to create a desired amount of friction between two flat surfaces without resorting to math. Their ...

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 ...
