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

One type of friction can waste energy even when two perfectly smooth surfaces move against each other, but researchers are getting a handle on how to attenuate or stop it completely ...

Learn how to solve a ladder friction problem and determine the minimum coefficient of friction. Step-by-step explanations make it easy to understand the physics behind ladder stability and forces in ...

For the first time, physicists in China have virtually eliminated the friction felt between two surfaces at scales visible to the naked eye. In demonstrating "structural superlubricity," the team, led ...

Schematic illustration of Friction Force Microscopy (FFM). The AFM cantilever, a small diving board-like structure about 200 micrometers long, 50 micrometers wide, and 1 micrometer thick, has a sharp ...
