Linked from

The 22 pages that link to Proper time, each with the reason it gives.

• Special relativityRelated: It distinguishes a clock's own elapsed time from frame-dependent coordinate time.

• Frame of referenceRelated: It distinguishes a clock's elapsed time from coordinate time assigned by a frame.

• Light coneRelated: Timelike paths inside a cone permit elapsed proper time; lightlike paths on it do not.

• Minkowski spacetimeRelated: The spacetime interval determines elapsed time along timelike paths.

• Gravitational time dilationRelated: Clock comparisons concern the proper time accumulated along each clock’s path.

• Spacetime intervalRelated: For timelike-separated events, the interval determines the elapsed proper time along an inertial path.

• Four-momentumRelated: It defines four-velocity, which provides a direct construction of massive-particle four-momentum.

• Time dilationRelated: It distinguishes a clock's experienced elapsed time from coordinate-time comparisons.

• Event (relativity)Related: It gives a clock-dependent duration between events on its worldline.

• Lorentz factorRelated: Proper time is the clock-time quantity related to coordinate time by γ.

• WorldlineRelated: It measures elapsed time along a timelike worldline.

• DurationRelated: Relativity makes measured duration depend on the clock’s path.

• Relativistic Doppler effectRelated: A moving source emits cycles according to its own proper time, not the observer’s coordinate time.

• Spacetime diagramRelated: It connects the length of a timelike worldline to a clock's elapsed time.

• Relativistic mechanicsRelated: It supplies the clock-independent time parameter for relativistic particle motion.

• Geodesics in general relativityRelated: A massive particle's geodesic locally extremizes elapsed proper time.

• Ladder paradoxRelated: It distinguishes local clock readings from frame-dependent comparisons of separated events.
