The Moon's gravity is much weaker than the Earth's.
The Moon's gravity is much weaker than the Earth's.

The Moon has practically no atmosphere, so there is no air resistance.

The mass of the paper folded into an airplane must be greater than the mass of the crumpled paper.
The mass of the paper folded into an airplane must be greater than the mass of the crumpled paper.

The pieces of paper were not dropped from a sufficient height for air resistance to affect their falls.

Answer 1

The correct response is: The Moon has practically no atmosphere, so there is no air resistance.

This is why both pieces of paper land at the same time; without air resistance to slow down the folded paper airplane, both items fall at the same rate under the influence of the Moon's gravitational pull.
