Newton’s equations predict that objects fall at the same rate in the absence of atmosphere.
Confirmed experimentally on Earth once vaccum chambers were constructive, and dramatically on the moon with a feather and hammer

Experiments with falling objects, from the time of Galileo onwards, demonstrated that objects of differing weight, but the same shape and density, did indeed fall at about the same rate. Also objects of the same weight, but differing shapes and/or densities fell at different rates; thus strongly supporting the hypothesis that the differences in rates of falling were due solely to air resistance. The later experiments, conducted in vacuum, simply confirmed beyond reasonable doubt this hypothesis.
That’s one of my favorite demonstrations! It was easy enough to know that this is true, but seeing it with one’s own eyes is shocking, or at least was for me.
