# Time Dialation

Einstein's concepts of relativity suggest that the velocity of an observer will affect the observer's perception of time. As one speeds up, the your wristwatch will count less time than a stationary clock.

Equationally, the effect is expressed as:

Where c is the speed of light, as v approaces c, v^2/c^2 approaches 1 and likewise the (1-v^2/c^2) approaches 0. Time, relative to the observer's clock, the watch at relativistic velocities counts less time.

This can be rewritten as:

= (1 - (v/c)^2)^(-1/2)

This function describes the relationship between t', the amount of time that elapses on the fast-moving clock and t, the amount of time that elapses on the clock at rest.
