A further development in atomic force microscopy now makes it possible to simultaneously image the height profile of nanometer-fine structures as well as the electric current and the frictional force ...

You’re not just imagining it, objects really are harder to shift the longer they sit there. A pair of scientists think they have discovered why. Have you ever had the impression that heavy items of ...

For a car to accelerate there has to be friction between the tire and the surface of the road. The amount of friction generated depends on numerous factors, including the minute intermolecular forces ...

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 ...

Quick, out behind the bike shed, Professors Pendry and Leonhardt are having a fight over a completely hypothetical situation. If we hurry, we should catch the end of round three. Science: it is ...

The Gauss gun. A very simple, yet very cool device. Check out this video. http://www.youtube.com/watch?v=Z7CyPtF0ChA There are many other examples of this Gauss gun ...

Frictional forces play a role in many activities – riding a bike, going bowling, and even lighting a match. When two surfaces rub together they create friction, which works to slow movement down. In ...

Energy is 'lost' or not used effectively when frictional forces occur. For example, when a bike applies its brakes and slows down the kinetic energy of the bike is transformed into heat energy in the ...
