Question

Why does the Earth have more gravitation pull than the moon?

- The moon is not as close as the Earth is to the Sun
- The Earth has more mass than the moon
- The distance between the Earth and the Moon gives Earth a stronger gravitational pull
- The Moon's mass is far too small to have a gravitational pull

Answer 1

The answer is: The Earth has more mass than the moon.

Answer 2

As accurately described by Einstein's theory of relativity, gravity is not necessarily a force, but a consequence of the curvature of space time that is caused by the uneven distribution of mass. But this could be understood more easily through Newton's Law of Universal Motion. The equation is shown below:

F = G(m₁m₂/d²), where
F is the gravitational force
G is called Newton's universal gravitation constant equal to 6.673×10⁻¹¹ N m² kg⁻²
m is the mass of the objects 1
d is the distance between the objects

Basing on the equation, the gravitational force depends on the mass the distance between the objects. So, when you compare the gravitational pull between Earth and moon. you do not need to include the effect of distance because, together. they have the same amount of d. So, it mainly depends on the masses. Since F is directly proportional to m, the greater the mass, the greater is the pull.

So, the answer is: The Earth has more mass than the moon.
