What is the formula for time dilation?

  1. $t' = t / \sqrt{1 - v^2/c^2}$
  2. $t' = t \sqrt{1 - v^2/c^2}$
  3. $t' = t / c^2 - v^2$
  4. $t' = t c^2 - v^2$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The formula for time dilation is $t' = t / \sqrt{1 - v^2/c^2}$, where $t'$ is the time measured by an observer in a moving frame of reference, $t$ is the time measured by an observer in a stationary frame of reference, $v$ is the velocity of the moving object, and $c$ is the speed of light.
