The electrons' angular momentum in the material—also called spin—thus decreases abruptly, much faster than the material can set itself in rotation. According to the conservation principle ...

Correlated spectrum of angular ... symmetry operation that comprises an arbitrary time translation combined with a corresponding rotational operation. The implication of this symmetry for ...

Some letters of the alphabet — like "A" or "T" — display a symmetry ... approximate conservation laws that are still valid, but nothing — not energy, not angular momentum, not linear ...

For this spinning Earth problem, we don't have to worry about torque (no net torque) so I'll just say that it's like a rotational ... to show this conservation of angular momentum.

This rotation can be described as angular momentum, a conserved measure of its motion that cannot change. Conservation of angular momentum explains why an ice skater spins more rapidly as she ...

Earth makes one complete rotation ... imparts angular momentum to a football as it is heft through the air toward the wide receiver. "One of the fundamentals of physics is the conservation of ...
