Acceleration $\vec a$
How much faster you go; how fast you are speeding up; how many extra metres-per-second your velocity increases with each second.
$$\vec a=\frac{\mathrm d\vec v}{\mathrm dt}$$
$\vec v$ is velocity and $t$ is time.
- Vector property
- Symbol: $\vec a$
- SI-unit: Metres-per-second-squared $\mathrm{m/s^2}$
