Researchers have demonstrated how to entirely suppress static friction between two surfaces. This means that even a minuscule force suffices to set objects in motion. Especially in micromechanical ...

A cook's reaction to cockroaches in the kitchen is a good approximation of a physicist's reaction to friction: not only is it undesirable, it is hard to get rid of. OK, our analogy falls at a last ...

Using high-speed photography and digital image correlation techniques, engineers show that friction along a faultline has a complex evolution during an earthquake that is dictated, in part, by slip ...

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 ...

• Excessive seal friction wastes energy, accelerates wear, and can lead to premature failure. • Too little friction makes a seal prone to leak. • Pressure-activated hydraulic seals minimize both ...

Friction is a force that resists the motion of one object against another. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Scientists began ...
