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 ...

Door handles, taps, playground slides, furry pets… Getting zapped by static electricity is a common experience. But the physics that causes the spark is surprisingly intricate. If you're getting ...

The upper figure shows the viscoelastic toy model proposed here, characterized by only six independent parameters. Surprisingly, this simple mechanical model produces complicated system dynamics, as ...

It's perhaps the second week of your introductory physics course. Your instructor starts talking about friction and writes the following two formulas on the board. Then there is probably some sort of ...

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 ...

IN 2009, World Aquatics banned a specific type of swimsuit from all international competitions in water sports, ruling that it gave athletes an unfair advantage. The development of this swimsuit ...
