What does the gravitational force between the Moon and Earth depend on?

Question

A their diameters and how far apart they are

B) their masses only

C their diameters only

D their masses and distance between the objects

Answer 1

The gravitational force between the Moon and Earth depends on:

D) their masses and distance between the objects.

According to Newton's law of universal gravitation, the gravitational force $F$ between two objects is directly proportional to the product of their masses $m_1$ and $m_2$ and inversely proportional to the square of the distance $r$ between their centers:

$$F=G\frac{m_1{m}_2}{r^2}$$

where $G$ is the gravitational constant. Thus, both the masses and the distance between the objects are essential factors in determining the gravitational force.
