# 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

 $$\large{ v_i = \frac { d \; l} {d \; t } }$$

### Where:

$$\large{ v_i }$$ = instantaneous velocity

$$\large{ d }$$ = displacement

$$\large{ l }$$ = length or distance

$$\large{ t }$$ = time
