Two objects of different masses falling freely near the surface of the Moon would

There is no atmosphere on the surface of the moon because

An object weighs 9 N on the surface of the Earth. What would be its weight, when measured on the surface of a planet where the acceleration due to gravity is 9 times that on the surface of the Earth?

If pieces of equal size of woods, wax and iron falling from a same height, which one will reach the surface of the earth first?

What happens to the gravitational force between two objects if the mass of one object is doubled and the distance between them is also doubled?

If the Moon is brought closer to the Earth such that its distance from the Earth becomes half of the original distance, then the gravitational force of attraction between the Earth and the Moon would…
