Now I get to do something with that force scale I built. I had a request some time ago to talk about friction. Friction is surprisingly complicated. When two surfaces rub against each other, why is ...

Technological limitations have made studying friction on the atomic scale difficult, but researchers have now made advances in that quest on two fronts. By speeding up a real atomic force microscope ...

Say we consider a simple experiment of balancing a wooden rod on two fingers. The finger on the left, (1), will remain stationary, whereas the finger on the right, (2), will be moved toward the left.

Beth Harris, a Raleigh mom and long-time science educator, returns with a fun and easy experiment where kids can test their strength with friction. Beth Harris, a Raleigh mom and long-time science ...

Without the force called friction, cars would skid off the roadway, humans couldn't stride down the sidewalk, and objects would tumble off your kitchen counter and onto the floor. Even so, how ...

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 ...

Explore the physics behind a penny on a spinning record player and the role of friction! 🌀💡 In this video, we break down the forces acting on the penny, explain how friction affects motion, and ...

“Dragging” ultracold ions across an optical lattice has provided important insights into friction. By tweaking the distance between the ions, Alexei Bylinskii, Dorian Gangloff and Vladan Vuletić of ...

This article has been updated to include comments from Raymond Goldstein and Patrick Warren. It is a mathematical puzzle that stumped Galileo, but researchers in France think they have discovered how ...
