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 ...

A suspended apparatus used to minimize friction during the experiment. The heavier brass cylinder and lighter ping-pong ball collide repeatedly against the transparent wall, reproducing 31 collisions ...

Physics experiments have changed the world irrevocably, altering our reality and enabling us to take gigantic leaps in technology. From ancient times to now, here's a look at some of the greatest ...

In classical physics, anything driven hard enough will eventually heat up, lose coherence, and settle into disorder. A new ...

I learned to respect friction, as a phenomenon with many nuances, when I was a graduate student. One day, while teaching a problem session in elementary mechanics, I unwisely invented a new problem to ...

Flux physics refers to continuous change in physical quantities, including energy transfer and dynamic equilibria. Flux is ...

Physicists often find thrifty, ingenious ways to reuse equipment and resources. What do you do with 800 square feet of scintillator from an old physics experiment? Cut it up and give it to high ...

The best part about living in Vermont is that we get to experience all of the seasons. Sometimes cool weather appears out of nowhere and we don’t have the proper attire so we rub our hands together to ...
