# Initial Velocity

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Initial velocity, abbreviated as $$v_i$$, is the starting point at which motion begins.

## Initial velocity formulas

$$\large{ v_i = v_f - a \; t }$$

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

Symbol English Metric
$$\large{ v_i }$$ = 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 $$\large{ sec }$$ $$\large{ s }$$
$$\large{ v_f }$$ = final velocity $$\large{\frac{ft}{sec}}$$ $$\large{\frac{m}{s}}$$
