Wrong again Grim. Sorry old chum, ya can`t win `em all.
The feathers/peas/mass comparison is not dropping these objects from 2,000 feet where air resistance looms up - called drag in the industry. It concerns dropping them from a few feet, where gravity is the only factor in the equation.
A feather with the same mass as a piece of lead as per your example, when dropped from a few feet will both hit the ground at exactly the same time on this very Planet we all love.
Any idiot knows that air resistance or drag is paramount in determining the terminal velocity of a specific body mass falling from a great height and is proportional to body mass and surface area.
Ever heard of a parachute Grim ?
