Time+Dilation

Equation: 1 divided by the square root of 1- v^2 divided by c^2.

C= speed of light 3X10^8 V= velocity

Ex. You are traveling at a speed of .8c for a time of 2 years(according to you). According to an outside oberver, how much time has passed? Y= 1.57 (no units) T= 3.33 (years)

Y= 1 divide the square root of 1- .8c^2 divided by C^2

T= 3.33 years
