What happens when objects of different mass are dropped under the same gravitational condition

They will land at the same time, as they did in Galileo's experiment where he dropped two balls of different weights off the leaning Tower of Pisa.  There was a similar experiment on the moon where a feather and a hammer were dropped, and landed at the same time.

We weigh differently in space due to gravitational pull or force. that is why you see astronauts waddle in these massive heavy outfits weighing over 100 pounds. however without gravity, a 300 pound man can jump and spring off in a jump as if he is 50 lbs

the amount of force he can use as a 300 pound is the same but now take that inertia or power on weighing 50 pounds and that is why you see th we same waddling astronauts on earth jumping around in space like frogs
