8. Centripetal Forces & Gravitation

Three identical satellites $A$, $B$, and $C$ are launched into circular orbits around Earth at different altitudes: $A$ is closest to Earth, $B$ is at a medium altitude, and $C$ is farthest from Earth. Rank the magnitude of the net gravitational force acting on each satellite due to Earth from greatest to least.

According to Newton's Law of Gravity, which two factors determine the magnitude of the gravitational force between two objects?

Which of the following best describes the effect of the Moon's gravity on $\mathrm{Earth}$?

Which statement correctly describes the factors affecting the gravitational force between two objects according to Newton's Law of Gravity? $F=\frac{G{m}_1{m}_2}{r^2}$

Why did Newton believe there was a force acting on the Moon?

According to Newton's Law of Gravity, what type of force acts between the Earth and the Moon? $F=G\frac{m\mathrm{\_E}m\mathrm{\_M}}{r^2}$
