Now I get to do something with that force scale I built. I had a request some time ago to talk about friction. Friction is surprisingly complicated. When two surfaces rub against each other, why is ...

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 ...

Friction is the force between two surfaces that are trying to slide across each other. Friction always slows down a moving object. The amount of friction depends on the material the two objects are ...

Friction is the force between two surfaces that are sliding, or trying to slide, across each other. For example, when you try to push a book along the floor, friction makes this difficult. Friction ...

It’s no wonder earthquakes are so difficult to predict. Even simple laboratory simulations of the friction breakdowns that send tectonic plates lurching into motion are maddeningly difficult to ...

The friction between a silicon ball and silicon wafer was measured in the experimental set-up shown on the left. The new research demonstrates that there is a direct relation between two effects: the ...

Controlling the friction between two moving surfaces — and possibly even reducing it to zero — is one of the outstanding challenges in modern tribology. Two recent discoveries may make this dream come ...

An interdisciplinary research team of the Institutes of Physical Chemistry and Physics of the University of Freiburg and the Max Planck Institute of Biophysics in Frankfurt-am-Main has discovered a ...

Memory fault: friction study could provide new insights into why earthquakes happen. (Courtesy: iStock/allanswort) Experiments by Sam Dillavou and Shmuel Rubinstein at Harvard University have, for the ...
