Time dilation (AQA A-Level Physics): Flashcards

Time runs at different rates in different reference frames

Inertial frames (constant velocity)

Time experienced by stationary observer

Time experienced by external observer (longer than proper time)

$t = \frac{t_0}{\sqrt{1 - \frac{v^2}{c^2}}}$

Always less than dilated time

Approximately 2.3 hours

Muon decay

$0.996c$

1.5 μs (or $1.5 \times 10^{-6}$ s)
