*It is constant for all [[object]]s near the [[Earth]]’s surface regardless of their [[mass]].
*Represented by the symbol 'g'.
*In the absence of [[drag]], all [[object]]s fall with the same [[acceleration]] due to [[gravity]].
*The value of g decreases with altitude and is slightly different at the poles and the equator due to the [[Earth]]’s shape.
*[[Galileo]]'s experiments demonstrated that [[object]]s fall at the same rate irrespective of their [[mass]].
*[[Free Fall|Free fall]] [[acceleration]] is used in various physics equations such as s = ut + 0.5gt² for distance and v = u + gt for final velocity.
