Recently, I gave my introductory physics course a fairly standard problem, based on the Matter and Interactions textbook. I've modified the question, but it goes something like this: Here's a diagram ...

This video shows how to apply the work–energy principle to real physical systems beyond ideal point particles. Learn how external work, internal forces, and energy losses are handled in practical ...

"Ever wondered how forces and energy come into play when Iron Man crashes into sand? In this video, we use the work-energy principle to analyze the forces at work in a high-impact sand crash scenario, ...

Sometimes you think you have a complete understanding of something and then BOOM—a simple problem throws everything out the window. Let's consider a very basic physics problem involving pushing a ...

The Chemical Brothers are back with another one of those block rockin’ beats. The veteran UK duo came out with their expansive single “The Darkness That You Fear,” a one-off follow-up to their 2019 ...
