Final Velocity

on . Posted in Classical Mechanics

final velocity 1Final 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 \(ft\;/\;sec\) \(m\;/\;s\)
