Learn how to calculate the speed of a mass in a circular pendulum with this clear physics tutorial! Step-by-step explanations make it easy to understand circular motion, energy, and angular velocity.

An international group of researchers has found that chiral phonons can create orbital current without needing magnetic elements – in part because chiral phonons have their own magnetic moments.

Chiral phonons are vibrations where atoms move in a circular pattern when energized, for example, by heat. As these vibrations travel through a material, they carry and spread tha ...
