generally confirm the existence of a non-contact friction force between surfaces separated by very small distances. What's behind it? As with many mysteries of physics, this one seems to have ...
Here’s the rub with friction — scientists don’t really know how it works. Although humans have been harnessing its power since rubbing two sticks together to build the first fire, the physics of ...
Imagine a world where your clothing generates electricity as you move—no batteries, no chargers, just energy from motion.
Science presenter Jon Chase explains friction. He describes how friction opposes or prevents motion, and demonstrates the force in action with an experiment involving two interleaved books.
Slip on banana peel, take a tumble: the classic comedy gag! Mabuchi Kiyoshi's serious search for scientific proof of that ...
When Isaac Newton inscribed onto parchment his now-famed laws of motion in 1687, he could have only hoped we'd be discussing them three centuries later.
Ice causes very little friction, which is why it is easy to slip over on an icy day. However, this is a good thing for ice skating and sledging. Friction is a force between two surfaces that are ...
Scientists have turned light into a "supersolid" for the first time, marking a groundbreaking achievement in physics that ...
Imagine a heavy book resting on a table. If you try to gently push the book across the table with the tip of your finger, it may first appear to remain motionless—it needs a lot more force to start ...
Some animals seem to have an instinctive understanding of physics, using gravity, friction, fluid dynamics, and even ...
"In a quantum theater, where bosonic particles (particles with integer spin) go, everyone can sit in the central seat, forming what is called a Bose–Einstein condensate—a superfluid state in which a ...
