Time Differential

 Time differential, abbreviated as \(\Delta t'\), is the time that has passed as measured by a stationary observer.

 

Time Differential formula
\(\large{ \Delta t' =  \gamma \; \Delta t  }\)
Symbol	English	Metric
\(\large{ \Delta t' }\) = time differential	\(\large{ sec }\)	\(\large{ s }\)
\(\large{ \gamma }\) (Greek symbol gamma) = Lorentz factor	\(\large{ dimensionless }\)
\(\large{ \Delta t }\) = time that has passed by the traveling observer	\(\large{ sec }\)	\(\large{ s }\)

 

Time Differential formula
\(\large{ \Delta t' = \frac{\Delta t}{\sqrt{1\;-\;\frac{v^2}{c^2} } }  }\)
Symbol	English	Metric
\(\large{ \Delta t' }\) = time differential	\(\large{ sec }\)	\(\large{ s }\)
\(\large{ \Delta t }\) = time that has passed by the traveling observer	\(\large{ sec }\)	\(\large{ s }\)
\(\large{ v }\) = velocity of the traveling observer	\(\large{\frac{ft}{sec}}\)	\(\large{\frac{m}{s}}\)
\(\large{ c }\) = speed of light	\(\large{\frac{ft}{sec}}\)	\(\large{\frac{m}{s}}\)
