Final Velocity

Final velocity, abbreviated as \(v_f\), is the ending point of motion.

 

Final velocity formula
\( v_f \;=\; v_i + a \; t  \)
Symbol	English	Metric
\(v_f  \) = final velocity	\(ft\;/\;sec\)	\(m\;/\;s\)
\( v_i  \) = initial velocity	\(ft\;/\;sec\)	\(m\;/\;s\)
\( a \) = acceleration	\(ft\;/\;sec^2\)	\(m\;/\;s^2\)
\( t \) = time	\(sec \)	\( s \)

  

Final velocity formula
\( v_f \;=\; 2 \; \bar {v}  -  v_i  \)
Symbol	English	Metric
\( v_f  \) = final velocity	\(ft\;/\;sec\)	\(m\;/\;s\)
\( \bar {v}  \) = average velocity	\(ft\;/\;sec\)	\(m\;/\;s\)
\( v_i  \) = initial velocity	\(ft\;/\;sec\)	\(m\;/\;s\)
