Friction in liquids arises from conservative forces between molecules and atoms. Although the hydrodynamics at the nanoscale is subject of intense research and despite the enormous interest in the non ...

Using high-speed photography and digital image correlation techniques, engineers show that friction along a faultline has a complex evolution during an earthquake that is dictated, in part, by slip ...

The rubber static friction coefficient μ s contributes, e.g., to the grip of tyres, shoes and windshield wipers, even though research is often focused on the sliding (dynamic) friction coefficient μ d ...

Friction is an intrinsic physical phenomenon to curling. Without it, objects in motion would move endlessly, without slowing down. This would cause many safety-related problems: Cars or trains could ...
