1.1 What is friction? Take this everyday example: when a coffee mug rests on a flat table, the kinetic frictional force is zero. There is no force trying to move the mug across the table, so there is ...

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 ...

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 ...

Winter brings drier air inside and outside our homes, even in typically humid Southern areas. With less humidity comes static electricity and clothes that cling to your body. You may think the ...

The lack of moisture in the air and the friction of scarves and hats during winter create prime conditions for staticky hair. Certain hair types, like fine and damaged hair, are more prone to static ...

I'll be honest—friction is pretty complicated. Imagine that I have a block of wood sliding on a table. In some way, the atoms on the surface of the wood block are interacting with the surface atoms on ...

Memory fault: friction study could provide new insights into why earthquakes happen. (Courtesy: iStock/allanswort) Experiments by Sam Dillavou and Shmuel Rubinstein at Harvard University have, for the ...
