Many people don't know too much about angular momentum—and that's fine. But what about figure skaters? Whether they understand the concept of angular momentum doesn't matter but they use it in one of ...

Introduction The bottle-flipping craze might be dying down, but it isn’t too late to investigate the physics of this internet sensation. Even if you’ve never heard of it, give this project a try—not ...

The University of Virginia is investigating the use of a magnetohydrodynamic (MHD) angular rate sensor to measure head angular acceleration in impact testing. Output from the sensor, which measures ...

If the angular velocity of a link in a mechanism is zero, does this imply that the angular acceleration of that link is also zero? The short answer to that question is NO. If ω(t) represents the ...

Consider the rotor of a gyroscope. The rotor is attached to a frame that is rotating about a fixed vertical axes with a constant rate of ω 1, and with the rotor rotating relative to that frame at a ...

Now that David Beckham won't be appearing at the London 2012 Olympics, other members of Team GB wanting to brush up on their free-kicks can rest easy. A physics students has figured out the optimum ...

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 ...

Diving has gotten a lot of strange attention this year, thanks to a lack of filtration chemicals that caused the water to turn from a pristine blue to a worrisome green, which Olympic officials are ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...
