2. Time dilation - Wikipedia

   en.wikipedia.org/wiki/Time_dilation

   Time dilation is the difference in elapsed time as measured by two clocks, either because of a relative velocity between them (special relativity), or a difference in gravitational potential between their locations (general relativity). When unspecified, "time dilation" usually refers to the effect due to velocity.

3. Gravitational time dilation - Wikipedia

   en.wikipedia.org/wiki/Gravitational_time_dilation

   Gravitational time dilation is a form of time dilation, an actual difference of elapsed time between two events, as measured by observers situated at varying distances from a gravitating mass. The lower the gravitational potential (the closer the clock is to the source of gravitation), the slower time passes, speeding up as the gravitational ...

4. List of relativistic equations - Wikipedia

   en.wikipedia.org/wiki/List_of_relativistic_equations

   Also, the velocities in the directions perpendicular to the frame changes are affected, as shown above. This is due to time dilation, as encapsulated in the dt/dt′ transformation. The V′ y and V′ z equations were both derived by dividing the appropriate space differential (e.g. dy′ or dz′) by the time differential.

5. Spacetime diagram - Wikipedia

   en.wikipedia.org/wiki/Spacetime_diagram

   Fig 4–2. Relativistic time dilation, as depicted in a single Loedel spacetime diagram. Both observers consider the clock of the other as running slower. Relativistic time dilation refers to the fact that a clock (indicating its proper time in its rest frame) that moves relative to an observer is observed to run slower. The situation is ...

6. Bondi k-calculus - Wikipedia

   en.wikipedia.org/wiki/Bondi_k-calculus

   In the k-calculus methodology, distances are measured using radar.An observer sends a radar pulse towards a target and receives an echo from it. The radar pulse (which travels at , the speed of light) travels a total distance, there and back, that is twice the distance to the target, and takes time , where and are times recorded by the observer's clock at transmission and reception of the ...

7. Clock drift - Wikipedia

   en.wikipedia.org/wiki/Clock_drift

   Time dilation is of practical importance. For instance, the clocks in GPS satellites experience this effect due to the reduced gravity they experience (making their clocks appear to run more quickly than those on Earth) and must therefore incorporate relativistically corrected calculations when reporting locations to users.

9. Experimental testing of time dilation - Wikipedia

   en.wikipedia.org/wiki/Experimental_testing_of...

   Relation between the speed and the Lorentz factor γ (and hence the time dilation of moving clocks). Time dilation as predicted by special relativity is often verified by means of particle lifetime experiments. According to special relativity, the rate of a clock C traveling between two synchronized laboratory clocks A and B, as seen by a ...
