Before an earthquake, static friction helps hold the two sides of a fault immobile and pressed against each other. During the passage of an earthquake rupture, that friction becomes dynamic as the two ...

Dynamic friction model with thermal and load dependency: modeling, compensation, and external force estimation The performance of a physically-motivated friction model with a parametric description of ...

Chemists and physicists shed light on a crucial aspect of friction: how things begin to slide. Using fluorescence microscopy and dedicated fluorescent molecules, they are able to pinpoint how and when ...

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 ...

The friction on a graphene surface can be dynamically tuned using external electric fields, according to researchers. The friction on a graphene surface can be dynamically tuned using external ...
