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 ...

Rotating objects carry angular momentum; this fact extends even to the tiniest of particles, such as photons. Photons possess not one but two distinct forms of angular momentum: spin angular momentum ...

Every dazzling jump on the ice—like Yuzuru Hanyu's quadruple Lutz at the 2017 Grand Prix of Figure Skating in Moscow, Russia—requires a mastery of balance, rotational speed and angular momentum. Aflo ...

Photons can carry angular momentum, not only due to their spin, but also due to their spatial structure. This extra twist has been used, for example, to drive circular motion of microscopic particles ...

Since energy is conserved (the gravitational force is conservative), we can use the work/energy equation to determine the speed of the satellite as a function of the distance R from O to P. Since the ...

Introduction You might have seen figure skaters spinning around quickly and then tucking their arms to spin faster—or opening them to spin more slowly. This happens, thanks to a physics concept known ...

Speedy Spinning Spheres! Using spheres, cylinders, and straws, the Crew and Dr. Rob learn about inertia, velocity, and conservation of energy due to angular momentum. STEM Challenge: Angular Momentum ...
