A snake moves without legs by the scales on its belly gripping the ground. It generates friction at the points needed to move forwards only and prevents its scales from being worn off by too much ...

Since his postdoctoral days at MIT, Hang Yu, associate professor of materials science and engineering, has been wrestling ...

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 ...

Physicists should “think big” when it comes to calculating the effects of friction on tiny nanomachines, according to researchers in the US, who say that they have strong evidence against the widely ...

Scientists may be one step closer to understanding the atomic forces that cause friction. They found a significant difference in friction exhibited by diamond surfaces that had been coated with ...
