In "Friction," tribologist Jennifer Vail shows how the fundamental force that resists motion keeps driving us forward.

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 ...

Earlier, we saw that the work done by friction on a particle sliding on a rough surface is negative, causing a loss in total mechanical energy as the particle slides. Here, we will address the ...

Scientists led by the University of Leicester have made an insight into superlubricity, where surfaces experience extremely low levels of friction While many of us are treading carefully to avoid a ...

Nanotribology is the study of friction, wear, and lubrication at the nanoscale. It focuses on understanding and controlling the interactions between surfaces in relative motion when the contact area ...

Humans have been making fire using friction for thousands of years, with evidence of its use found in archaeological records across different cultures worldwide. Fire by friction is a testament to ...

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 ...

Robots may soon mimic the human sense of touch, with advances in flexible tactile detection aiming to endow them with the ability to sense friction and slip. Polymer optical fiber knots are at the ...
