The moons is smaller than the Earth and they speculate it has no Iron core which greatly reduces its weight. The less you weigh the less gravity. Density is a measure of gravity. Mass has nothing to do with it, If you had a cheeto the size of a planet or a Iron ball the size of a planet, The Iron ball is denser so it will have a greater gravitational force. Also a black hole is smaller than any planet yet it has a strong gravitational force ! It is extremely dense

Gravitational force has to do with the size and density of the object. As the moon is smaller than the earth and is not made up of the dense material that earth is, it's gravitational force therefore is less.

gravitational force also takes mass into account. if you look at Newton's equation for calculating gravitational force, you will see that mass is an important part.
because the moon is much smaller than the earth, its mass is less and it has a smaller gravitational force.

Energy exists in 3 states: orbital accelerative (matter), oscillatory (heat and light) and motional.
Motional energy causes gravity.
Basically motional energy is energy in motion (as opposed to energy that has formed a mass or energy that produces heat or light). The amount of gravitational force an object has depends on the mass of the object (the amount of energy devoted to mass) and the distance between it and another object. The more energy there is in the mass of matter (the denser the matter) the more motional energy will be expended attracting other objects. (If an object with light mass pulled other objects that hard it's own mass would disintegrate.)
To get really geeky, here's the forumla for it:
F = G(mass1*mass2)/D squared.
(G is the gravitational constant, which has the same value throughout our universe.)

the gravitational force is actually a force of attraction between the two bodies, according to neuton's law this force depends on the mass of both bodies and the distance between them, the mass of the moon is less than the mass of the earth, that's why the force is less on the moon.

Because the moon is smaller than Earth and has less mass.

Force of gravity is proportional to mass of object one (person or anything) times mass of object two (earth v. moon) divided by the distance between the objects squared.

Because the moon doesn't have as much mass as the earth.
