Coordinate time & Proper time in Special Relativity: What's the difference & Why? |

We explain the concept of Coordinate time & Proper time in Relativity. Where the Coordinate time and Proper time differ, where they don't differ and most importantly, Why? -are the questions answered here. We give the definition of Proper time. Explain when and why proper time is needed. How the concept of Coordinate time comes into the picture, when and how Coordinate time differs from Proper time. We demonstrate, with spacetime diagram, how proper time interval between a pair of events is calculated from coordinate time data for those two events. We also explain how the proper time interval formula can be used to relate coordinate time reading of an individual event to its corresponding proper time reading. We also elaborate which observer can read off proper time interval between two events from his/her clock only, instead of calculating it like other observers do using their coordinate time data. Finally we demonstrate how spacetime coordinates of an event on a given world-line can be written as functions of proper time value for that event. In other words, proper time values for the events on a given world-line can be used to parametrize that world-line, so that the dynamics of an object moving along that world-line can be studied.
