The 18 pages that link to Principle of least action, each with the reason it gives.

• Hamiltonian mechanicsNarrower topic: Hamiltonian mechanics is another formulation of the same variational dynamics.

• Calculus of variationsRelated: Classical mechanics turns particle trajectories into extrema or stationary points of an action.

• Euler–Lagrange EquationRelated: Applying the equation to the action produces the equations of motion of classical systems.

• Fermat's principleRelated: Fermat's principle is its optical counterpart, with travel time playing the role of action.

• William Rowan HamiltonRelated: Hamilton’s mechanics connects motion to stationary action rather than force laws alone.

• Émilie du ChâteletRelated: She developed and defended an account of this principle in her scientific writing.

• Hamilton–Jacobi equationRelated: The equation describes the action accumulated by paths satisfying this variational principle.

• Action (physics)Compared with: The name can wrongly suggest that every physical path minimizes action.

• D'Alembert's principleCompared with: It compares entire trajectories; D'Alembert's principle compares instantaneous admissible displacements.

• Hamilton's principleCompared with: The name suggests minimization, whereas Hamilton's principle requires stationarity.

• Principle of Sufficient ReasonCompared with: Its mathematical extremum principle can look like a reason for events without settling metaphysical explanation.

• Newton's first lawCompared with: It offers a different formulation of mechanics, in which free motion follows from an action principle.

• Pierre Louis MaupertuisRelated: Maupertuis advanced an early formulation that became central to later variational mechanics.

• Analytical mechanicsRelated: It provides a single path-based rule for deriving equations of motion.

• Classical physicsRelated: It provides a common variational foundation for classical mechanics and fields.

• Virtual workCompared with: It characterizes motion through path variation, whereas virtual work states an instantaneous force balance.

• Joule-secondRelated: Its central quantity has joule-second units.

• Principle of minimum energyCompared with: It selects motion histories through a stationary action, not static states through minimum energy.
