If the $centerofpressure$ moves in front of the $centerofgravity$ on a rocket, what will happen to the rocket?

According to Newton's Law of Gravity, if the distance between two objects is increased by a factor of three, what will the new gravitational force between them be compared to the original force $F$?

According to Newton's Law of Gravity, the Earth and the Moon attract each other with gravitational forces. Which object exerts a greater gravitational force on the other? $F=\frac{G{m}_1{m}_2}{r^2}$

According to Newton's Law of Gravity, which of the following factors affect the magnitude of the gravitational force between two objects? $F=\frac{G{m}_1{m}_2}{r^2}$

According to Newton's Law of Gravity, if the gravitational force between two masses is initially $F$ when they are a certain distance apart, what will be the new force if the masses are moved so they are only one-eighth as far apart?
