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.

Static electricity is so commonplace that it can come across as simple. Other teams are investigating how surface area and velocity during impact might govern charge transfer, and how the breaking ...

This familiar phenomenon has puzzled researchers for centuries, but experiments are finally making sense of its unruly ...

Applied to college life, friction-maxxing might include going to a professor’s office hours for the first time or taking an ...

Friction requires contact. Two surfaces rub together. Energy is lost. Heat is generated. Things slow down. The universe makes sense again. Except… now it doesn’t. Because researchers have decided—very ...

Have you ever watched a mile-long freight train rumble by and wondered how one locomotive can pull more than a hundred fully loaded cars? The locomotive weighs maybe 150 metric tons, and each car is ...

Learn how to calculate the minimum static friction in a half Atwood machine! This physics tutorial explains the concepts, formulas, and step-by-step method for students and enthusiasts. #Physics ...

I don’t know who invented this crazy challenge, but the idea is to put someone in a carved-out ice bowl and see if they can get out. Check it out! The bowl is shaped like the inside of a sphere, so ...

Most of us have a fickle relationship with friction. We panic when we suddenly lose it, take it for granted when it’s working in our favor, and curse it when it becomes a drag. Whatever our momentary ...
