  Classical and quantum mechanical descriptions of motion are fundamentally
different. The universality of free fall (UFF) is a distinguishing feature of
the classical motion (which has been verified with astonishing precision),
while quantum theory tell us only about probabilities and uncertainties thus
breaking the UFF. There are strong reasons to believe that the classical
description must emerge, under plausible hypothesis, from quantum mechanics. In
this Essay we show that the UFF is an emergent phenomenon: the coarse-grained
quantum distribution for high energy levels leads to the classical distribution
as the lowest order plus quantum corrections. We estimate the size of these
corrections on the E\"otv\"os parameter and discuss the physical implications.
