# Instantaneous Velocity

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Instantaneous velocity, abbreviated as $$v_i$$, as the change in time approaches 0, is the velocity at a particular moment in time along its path.

## Instantaneous Velocity formula

$$\large{ v_i = \frac { d l} {d t } }$$
Symbol English Metric
$$\large{ v_i }$$ = instantaneous velocity $$\large{\frac{ft}{sec}}$$ $$\large{\frac{m}{s}}$$
$$\large{ d l }$$ = length or distance (derivative) $$\large{ft}$$ $$\large{m}$$
$$\large{ d t }$$ = time differential (derivative) $$\large{sec}$$ $$\large{s}$$
