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 ...

Have you ever watched a mile-long freight train rumble by and wondered how one locomotive can pull more than a hundred fully loaded cars? The locomotive weighs maybe 150 metric tons, and each car is ...

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 ...

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 ...

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: ...

Liquid assets: how to make coins flow like a fluid. (Courtesy: Yasinul Karim and Eric Corwin) Friction in one part of a system can be reduced by boosting friction elsewhere. That is the curious and ...

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, ...

Friction is a key phenomenon in applied physics, whose origin has been studied for centuries. Until now, it has been understood that mechanical wear-resistance and fluid lubrication affect friction, ...

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 ...

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 ...

If the 1964 Winter Olympic gold medalist for downhill alpine skiing faced off against every qualifying participant in the same event at the Beijing games in 2022, Egon Zimmermann would have returned ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. Records say that in 15th-century China, workers hauled 100-ton ...
