Time Differential

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

 

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

 

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