Many NHL players like Connor McDavid and Nathan MacKinnon skate faster than 20 miles per hour every game. Hall of Famer Bobby ...

At a busy street crossing, people wait for the signal to change. When one person steps out first, others soon follow. Scientists in Amsterdam have found that this same kind of behavior happens at a ...

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

In this video, we break down the concept of the coefficient of friction in AP Physics 1, explaining how static and kinetic friction work and how they affect motion. Clear examples and reasoning help ...

MIT scientists have coaxed atoms into an exotic “edge state” for the first time, allowing them to flow completely friction-free. The breakthrough could lead to better superconductor materials. As ...

Although robotic devices are used in everything from assembly lines to medicine, engineers have a hard time accounting for the friction that occurs when those robots grip objects - particularly in wet ...

In this video, we explain the capstan equation and how friction affects a rope or string wrapped around a surface. You’ll learn where the equation comes from, what each term means, and how it’s ...
