The 11 pages that link to Action (physics), each with the reason it gives.

• Noether's theoremNarrower topic: The theorem starts from transformations that leave this quantity invariant.

• Gauge symmetryRelated: Gauge transformations are tested by whether they preserve the action.

• Path integral formulationRelated: Each history’s action sets its phase in the quantum sum.

• Principle of least actionBroader topic: The principle selects paths by requiring this functional to be stationary.

• Reduced Planck constantNarrower topic: ℏ has the units of action and sets its characteristic quantum scale.

• Hamilton's principleNarrower topic: Hamilton's principle selects paths by requiring this integral to be stationary.

• Correspondence principleRelated: Comparing action with Planck's constant identifies when classical approximations apply.

• Pierre Louis MaupertuisRelated: Maupertuis’s principle assigns a special role to action accumulated along a physical trajectory.

• Noether's second theoremRelated: The symmetry condition applies to the action whose variation produces the field equations.

• Joule-secondNarrower topic: The joule-second is the SI unit used to measure action.

• Symmetry-based models (mathematical physics)Related: Symmetry-based models commonly specify dynamics by requiring the action to remain invariant.
