Physicists in the US have made a peculiar discovery about how a small object slides over a rapidly rotating lubricated disk. They have found that if the object is tilted so that it only touches the ...

Friction is an intrinsic physical phenomenon to curling. Without it, objects in motion would move endlessly, without slowing down. This would cause many safety-related problems: Cars or trains could ...

I'll be honest—friction is pretty complicated. Imagine that I have a block of wood sliding on a table. In some way, the atoms on the surface of the wood block are interacting with the surface atoms on ...

IT is universally assumed that the force resisting the sliding of one body over another acts in a direction opposite to the relative velocity. However, no recent test of this law appears to have been ...

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, ...
