Learn how to calculate the angular velocity required to create artificial gravity in a rotating system. This video explains the physics behind centripetal acceleration, rotation radius, and angular ...

When a magnetic material is bombarded with short pulses of laser light, it loses its magnetism within femtoseconds (10 –15 seconds). The spin, or angular momentum, of the electrons in the material ...

In an introductory physics course, there are three big ideas. There is the work-energy principle, the momentum principle and then the angular momentum principle. I'll skip the work-energy principle ...
