# Gravitational acceleration $g$

All objects fall equally fast (with the same acceleration) due the gravity, regardless of their mass (ideally; in a vacuum). The acceleration everything falls with is called the gravitational acceleration $g$. On Earth’s surface, it has a value around:

$$g\approx 9.8\,\mathrm{m/s^2}$$

The value varies with around $\pm 0.02\,\mathrm{m/s^2}$ depending on location.
