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

A quadruped robot has learned to walk across slippery, uneven terrain entirely through simulation, ...

Robots acting as macroscale analogs of active nanoparticles stop moving through friction alone, revealing a self-sustained cooling effect without external input. (Nanowerk News) How can a horde of ...

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 ...

Explore the fascinating physics of chain motion over a table under frictional forces. Learn how friction affects movement, energy, and dynamics in this clear and engaging demonstration. Perfect for ...

Torque required to put a bearing into motion from rest is usually higher than that required to keep it running once it starts. Starting friction, therefore, has an important influence on the power ...
