Comment on “Why does a ball fall?: A new visualization for Einstein's model of gravity” [Am. J. Phys. 84, 396–402 (2016)]

A simple analytical approach that allows us to recover Newtonian physics from Schwarzschild's metric is proposed. The method elucidates why the tiny modification of the metric due to gravity entails a significant change of motion of a freely falling body.
