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

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

I don't normally watch many NASCAR races, but I do come across some NASCAR videos online. Sometimes these clips become the basis of a great physics problem. In this case, it's a 21-car crash at the ...

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

Frictional experiment: artist’s impression of the metainterface between a rigid piece of glass (top) and a metasurface (bottom). The textured regions are where the glass and metasurface are in contact ...

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 ...

COLUMBUS, Ohio – An engineer at Ohio State University recently demonstrated the world's first method for directly measuring friction between tiny microelectromechanical-system (MEMS) parts. Using an ...

Irregularities present on a surface are often described as surface roughness or texture. These surface textures such as grooves and dimples impart friction, which is the force between two sliding ...
