Answer:

What is the difference between fall of parachute on the earth and that of the moon? Parachute acquires upthrust of air so fall is with uniform velocity. Upthrust of air is not acted on parachute and falls with acceleration equal to acceleration due to gravity. Free-fall is not experienced.

Answer:

Parachutes operate because of drag and wind resistance. They "catch" the air because of their large surface area and light weight. The parachute doesn't hold you up so much as the air holds the parachute.

Since there is no atmosphere on the moon, there is nothing to "catch". First off, if you deployed a parachute above the moon's surface, it would not unfurl because there would be no air resistance to pull it open. So it would essentially remain a wad of fabric plummeting with you to the moon's surface. Because there is no air to hold the chute up, you'd simply continue falling until you and the wadded up parachute hit the moon's surface.

There is a video of one of the Apollo astronauts on the moon's surface recreating Galileo's feather and cannon ball experiment; where feather and a hammer were dropped at the same time. On Earth, the cannonball in Galileo's experiment hit the ground first while the feather gently drifted towards the ground because of air resistance; however on the moon, both the feather and the hammer hit the ground at the same time. This is because on the moon, there is no atmosphere for the feather to catch and hold it up.
