Researchers have uncovered friction without contact—driven entirely by magnetic interactions. As two magnetic layers slide, ...

Sometimes you think you have a complete understanding of something and then BOOM—a simple problem throws everything out the window. Let's consider a very basic physics problem involving pushing a ...

Researchers at the University of Konstanz have uncovered a new mechanism of sliding friction: resistance to motion that ...

A good old game of carrom has really stood the test of time. Set up a board and people around will flock to it while practising their finger gymnastics. You may not have noticed but the game often ...

Add Yahoo as a preferred source to see more of our stories on Google. In earthquakes, the principle shows how one part of a fault slipping can unleash movement across miles of crust. (CREDIT: ...

In a recent stunt, a Ford crew hitched an all-electric F-150 pickup truck to a freight train filled with 42 more F-150s. Then a driver hit the throttle, and the pickup truck towed the 1.3 ...

The familiar heat, wear and general grinding to a halt of friction are all caused by what's going on at the microscopic level when two things rub. And down there, even the smoothest surfaces usually ...

An international team of researchers says that it has measured the spin-dependent component of friction of a single atom as it slides across a magnetic surface, for the first time. The team used a ...

Is friction real? Once, with the quiet certainty of someone who just stayed up all night in the company of equations describing concrete, my college roommate told me that friction was made up. Now, ...

Explore 25 science experiments that defied the laws of physics, revealing mind-bending phenomena that challenge intuition.

Nanomachines will depend on our knowledge of friction, heat transfer and energy dissipation at the atomic level for their very survival. In the scramble to revolutionize the world with nanotechnology ...
