The gravitational pull between the Earth and the moon is governed by Newton's law of gravitation, which states that every mass attracts every other mass with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

In the case of Earth and the moon, both bodies exert a gravitational force on each other. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. This means that while the Earth does exert a force on the moon, the moon exerts an equal force back on the Earth. Therefore, both the Earth and the moon pull on each other with the same strength, despite their differences in mass. This mutual attraction is what keeps the moon in orbit around the Earth.

Understanding this principle illustrates that gravitational forces are not about the strength of the objects' mass alone but about their interaction as equals in terms of exerted forces.
