Solve a basketball jump physics problem by tracking how mechanical energy changes from takeoff to peak height. This video explains kinetic energy, gravitational potential energy, and energy ...

Minimum height to loop the loop using conservation of energy. This video explains how gravitational potential energy converts into kinetic energy and why a precise starting height is required to ...

A longstanding goal in physics has been to link general relativity with quantum theory and so unify the forces of nature. Theories of quantum gravity, however, are plagued by the weak theoretical ...

Try as they might, scientists can’t truly rid a space or an object of its energy. But what “zero-point energy” really means ...

The quest for unlimited and clean energy has been a long one, with over fifty-plus years in the endeavor to find new ways to combat climate change while also providing better energy solutions. One ...

In the Swiss municipality of Arbedo-Castione, a 70-meter crane stands tall. Six arms protrude from the top, hoisting giant blocks into the sky. But these aren’t building blocks, and the crane isn’t ...
