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 ...

Scientists developed a new model, which shows that rubbing two objects together produces static electricity, or triboelectricity, by bending the tiny protrusions on the surface of materials.

Find out about how friction acts against movement and how this can be useful. Bitesize Scotland Science article for learners at Second Level Curriculum for Excellence.

Static friction operates between two surfaces that aren't moving relative to each other, while kinetic friction acts between objects in motion.

Physicists refer to this as "dry" static friction (there being no lubricant), also known as Coulomb friction. The effect of Coulomb friction on motion is important in many application scenarios.

No matter what that Intro to Physics book says, you can't calculate the "work done by friction." Nope. Doesn't work. Don't even try it.

Greek philosopher Thales of Miletus first reported friction-induced static electricity in 600 BC. After rubbing amber with fur, he noticed the fur attracted dust. “Since then, it has become clear that ...
