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 ...

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 ...

Scientists have made an insight into superlubricity, where surfaces experience extremely low levels of friction. This could benefit future technologies by reducing energy lost to friction by moving ...

You know that two surfaces mate, but what is a friction clutch or brake? Using friction has been the most popular way to engage and stop loads since the 1800s. Surfaces interact with ...
