# Time dilation due to fthe time interval between two co-local events

## Description

Time dilation is an actual difference of elapsed time between two events as measured by observers either moving relative to each other or differently situated from gravitational masses.

( e.g. An accurate clock at rest with respect to one observer may be measured to tick at a different rate when compared to a second observer’s own equally accurate clocks).

The formula for determining time dilation in special relativity is depended on the Lorentz factor and the time interval between two co-local events for an observer in some inertial frame.

## Variables

Δt’ | time interval between those same events, as measured by another observer, inertially moving with velocity v with respect to the former observer (sec) |

γ | Lorentz Factor (dimensionless) |

Δt | time interval between two co-local events (i.e. happening at the same place) (sec) |
