Linked from

The 10 pages that link to Energy–momentum relation, each with the reason it gives.

• Minkowski spacetimeRelated: It expresses energy and momentum through spacetime-invariant quantities.

• Dispersion relationRelated: Replacing energy and momentum with wave frequency and wave number gives a relativistic dispersion relation.

• Four-momentumRelated: It expresses the invariant norm of four-momentum as the particle’s rest mass.

• Invariant massRelated: Applied to total system energy and momentum, it gives the invariant mass.

• Klein–Gordon equationRelated: Replacing energy and momentum with quantum operators leads to the free-particle equation.

• Relativistic momentumRelated: It constrains the energy and momentum that any object of a given rest mass can have.

• Relativistic Doppler effectRelated: Photon energy shifts alongside frequency, but this relation is distinct from the kinematic Doppler transformation.

• TachyonRelated: Applying it to a tachyon requires a negative mass-squared parameter and yields counterintuitive energy behavior.

• Massless particleRelated: Setting invariant mass to zero gives energy equal to momentum times the speed of light.

• Relativistic quantum mechanicsRelated: Relativistic quantum equations encode this relation in their particle-energy spectra.
