Learn how to analyze tipping a block and calculating friction in this physics tutorial. Step-by-step explanations cover forces, torque, and frictional calculations, helping students understand the ...

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 ...

Of course, the study of friction is nothing new; and to explain the 20th-century crisis, and to understand where tribology ...

Many NHL players like Connor McDavid and Nathan MacKinnon skate faster than 20 miles per hour every game. Hall of Famer Bobby Hull was once clocked at 29.3 miles per hour. Scientists once tracked Hull ...

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

Heh, maybe the problem is the premise. What real surface made of matter would even come close to this? Strikes me too as a case of theoreticians being wankers. Maybe I'm unimaginative, but I can't see ...

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 ...
