Why does the mass of planets affect the gravity on their surface but the mass of objects doesn’t affect how fast they fall.

Question

Why does the mass of both objects not factor? Did I misunderstand the reason for differing gravity on other planets?

Answer 1

It does! Sort of. The mass of the object you drop decides how fast Earth falls *towards it*. That speed is just going to be really *really* slow no matter what you drop.
