Researchers have uncovered friction without contact—driven entirely by magnetic interactions. As two magnetic layers slide, ...

Researchers at the University of Konstanz have uncovered a new mechanism of sliding friction: resistance to motion that ...

Researchers found friction can occur without contact, driven by magnetic dynamics, and does not always increase with load. The effect could enable controllable, wear-free technologies.

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 ...

The relationship between friction and load, quantified three centuries ago, has an exception when the interaction causes ...

Friction is a force that always opposes motion. Force is measured in newtons (N). A force is a push or a pull. Contact forces arise between two objects which are in contact. Non-contact forces act ...

Why is pancake syrup an example of a resistive force? Some forces are called contact forces because they require objects to touch. One is tension force, found in stretched wires. Another is the force ...

Wear has major impacts on everything from the bearing of a wind power plant to an artificial hip joint. However, the exact cause of wear is still unclear. Scientists now show that the effect occurs at ...

Space to play or pause, M to mute, left and right arrows to seek, up and down arrows for volume. Friction is a force that exists when two surfaces rub up against each other. For example, this cup on ...
