Researchers have uncovered friction without contact—driven entirely by magnetic interactions. As two magnetic layers slide, ...

Researchers at the University of Konstanz have uncovered a new mechanism of sliding friction: resistance to motion that ...

Technological limitations have made studying friction on the atomic scale difficult, but researchers have now made advances in that quest on two fronts. By speeding up a real atomic force microscope ...

Say we consider a simple experiment of balancing a wooden rod on two fingers. The finger on the left, (1), will remain stationary, whereas the finger on the right, (2), will be moved toward the left.

The relationship between friction and load, quantified three centuries ago, has an exception when the interaction causes ...

“Dragging” ultracold ions across an optical lattice has provided important insights into friction. By tweaking the distance between the ions, Alexei Bylinskii, Dorian Gangloff and Vladan Vuletić of ...

Learn how to determine the coefficient of friction by tipping a block. A practical physics approach to understanding friction ...

Here’s the rub with friction — scientists don’t really know how it works. Although humans have been harnessing its power since rubbing two sticks together to build the first fire, the physics of ...

Friction results from a set of complex processes that act together to resist relative motion. Despite this complexity, friction is often described using simple phenomenological expressions that relate ...
