1.1 What is friction? Take this everyday example: when a coffee mug rests on a flat table, the kinetic frictional force is zero. There is no force trying to move the mug across the table, so there is ...

Background With regard to sliding friction sports floor manufacturers focus on comfort and performance aspects of athletes. In relation to safety aspects standardisation bodies rather concentrate on ...

Atoms slip against one another, eventually sticking in various combinations. Tectonic plates do the same, sliding across each other until they stick in a stationary state. Everything from the tiniest ...

A new review argues that surgical suturing is a sequence of tribological events in which friction must be controlled stage by ...

A new experimental method based on atomic force microscopy allows the investigation of friction at the scale of individual atoms. A directional dependence of friction, also known as friction ...

A new approach for studying friction on ice helps explain why the ease of sliding depends strongly on temperature, contact pressure, and speed. Figure 1: This graphic shows how the hardness of ice ...
