# Instantaneous Velocity

Written by Jerry Ratzlaff on . Posted in Thermodynamics

Instantaneous velocity is the velocity at a particular moment in time along its path.

## formula

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

Where:

$$v_i$$ = instantaneous velocity

$$d$$ = displacement

$$l$$ = distance or length

$$t$$ = time
