Friction is a key phenomenon in applied physics, whose origin has been studied for centuries. Until now, it has been understood that mechanical wear-resistance and fluid lubrication affect friction, ...

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 ...

Using high-speed photography and digital image correlation techniques, engineers show that friction along a faultline has a complex evolution during an earthquake that is dictated, in part, by slip ...

Friction at the atomic scale appears to depend on the speed at which two surfaces move past each other. This surprising behaviour was observed as the tip of an atomic force microscope (AFM) moves ...

Researchers found friction can arise without contact, driven by magnetic dynamics, and doesn't always increase with load but peaks when magnetic ordering becomes frustrated. (Nanowerk News) ...

I'll be honest—friction is pretty complicated. Imagine that I have a block of wood sliding on a table. In some way, the atoms on the surface of the wood block are interacting with the surface atoms on ...
