Initial Velocity

Initial velocity, abbreviated as \(v_i\), is the starting point at which motion begins.

 

Initial velocity formulas

\(\large{ v_i = v_f - a \; t }\)

\(\large{ v_i = \frac { s }{ t }  - \frac { 1 }{ 2 }\; a \; t }\)

Where:

\(\large{ v_i  }\) = initial velocity	\(\large{\frac{ft}{sec}}\)	\(\large{\frac{m}{s}}\)
\(\large{ a }\) = acceleration	\(\large{\frac{ft}{sec^2}}\)	\(\large{\frac{m}{s^2}}\)
\(\large{ s }\) = displacement	\(\large{ ft }\)	\(\large{ m }\)
\(\large{ t }\) = time	\(\large{ sec }\)	\(\large{ s }\)
