Irregularities present on a surface are often described as surface roughness or texture. These surface textures such as grooves and dimples impart friction, which is the force between two sliding ...

When high-frequency shaking occurs at an interface between two solids, recent experiments have revealed that the frictional forces between the objects can be weakened. Through a simple new experiment ...

Friction is responsible for about twenty percent of the world energy consumption. The main reason for this is that frictional forces slow down the motion of surfaces in contact: think of the moving ...

You might have seen some of the viral videos of this giant steel slide at Belle Isle Park in Michigan, which temporarily closed this summer because riders were sliding so fast they were losing contact ...

Uplift resistance is a critical indicator for assessing the stability of buried pipelines under varying load conditions. To date, most studies on uplift resistance have focused on pipelines buried in ...

Atomic friction: tiny effect may never be measured. (Courtesy: Shutterstock/Dmitriy Rybin) An excited atom decaying in a vacuum experiences a force very similar to friction, according to calculations ...
