Initial Velocity

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

 

Initial Velocity formulas

\(\large{ v_i = v_f - a \; t }\)
\(\large{ v_i = \frac { s }{ t }  - \frac { 1 }{ 2 }\; a \; t }\)
\(\large{ v_i =  \frac{ v_f }{ a_v  \; \left( T_f \;- \; T_i \right) \;+\; 1 }  }\)	(volumetric thermal expansion coefficient)

Where:

\(\large{ v_i }\) = initial velocity

\(\large{ a }\) = acceleration

\(\large{ s }\) = displacement

\(\large{ T_f }\) = final temperature

\(\large{ T_i }\) = initial temperature

\(\large{ t }\) = time taken

\(\large{ v_f }\) = final velocity

\(\large{ \alpha_v }\)  (Greek symbol alpha) = volumetric thermal expansion coefficient
