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

1.1 What is friction? Take this everyday example: when a coffee mug rests on a flat table, the kinetic frictional force is zero. There is no force trying to move the mug across the table, so there is ...

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

"Join me as we dive into the core concepts of forces and motion! In this video, we’ll review Newton’s Laws of Motion, explore how forces affect objects, and break down key principles like acceleration ...

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 ...
