The conserved quantity arising from a rotational invariance. Combine with rotational-dynamics for the classical mechanics approach and quantum-mechanics for the QM interpretation
When to Use this Tag
angular-momentum refers to all situations where a quantity is conserved due to rotational invariance. This may occur both in classical-mechanics (esp. rotational-dynamics) as well as in quantum-mechanics. Usually, you should combine angular-momentum with another tag referring to the framework in which you work.
