Explore how forces and friction work to hold a block against a vertical wall. This video explains normal force, frictional force, and equilibrium conditions, showing how these forces balance to ...

The question is not how to eliminate friction. The question is how to manage it so it becomes traction and traction becomes forward motion.

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

How much do you know about friction? Jennifer R. Vail's charming, if sometimes technical, "biography" of the force showcases its amazing and largely overlooked role in everything from climate change ...

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 ...

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 ...

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 ...

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 ...

Scientists have made an insight into superlubricity, where surfaces experience extremely low levels of friction. This could benefit future technologies by reducing energy lost to friction by moving ...
