Without the force called friction, cars would skid off the roadway, humans couldn't stride down the sidewalk, and objects would tumble off your kitchen counter and onto the floor. Even so, how ...

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 ...

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 ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Rougher surfaces cause more friction. For an object to move, there must be a force upon it - this is usually a push or a pull. As the object starts to move, another force occurs between the object and ...
