Question

as the earth and the moon move away from each other in orbit, what happens to the gravitational forces between the two celestial masses? select one a. not enough information to determine b. it decreases c. it remains the same since gravity is constant d. it increases

Explanation:

The gravitational force between two masses is given by Newton's law of universal gravitation $F = G\frac{m_1m_2}{r^2}$, where $G$ is the gravitational constant, $m_1$ and $m_2$ are the masses of the two objects, and $r$ is the distance between their centers - of - mass. As the Earth and moon move away from each other ($r$ increases), with $G$, $m_1$ (mass of Earth) and $m_2$ (mass of moon) remaining constant, the gravitational force $F$ decreases.

Answer:

B. It decreases
