# Formula

$\overline{a} = \frac{\Delta V}{\Delta T} \;\;\;\; \text{or} \;\;\;\; \text{Average Acceleration} = \frac{\Delta\text{Velocity}}{\Delta \text{Time}}$

$\Delta$is delta, meaning difference. The lowercase letter for delta is $\delta$. The bar over $\overline{a}$ means average

# Derivation

$\text{Velocity}=\frac{m}{s}\newline \text{Time}=s\,(\text{Second})\,\newline \therefore \frac{v}{t} = \frac{m/s}{s} = \frac{m}{s^2}$

See velocity

# Unit

The unit for Acceleration is

$\frac{m}{s^2} \; \text{or} \; \frac{\text{Metre}}{\text{Second Squared}}$
