How is the gravitational force between to objects related to their mass

Two satellites of equal mass are in circular orbit around a planet. Satellite b is twice as far out. Which feels a stronger gravitational force?

The space shuttle is orbiting the Earth clockwise. Which vector shows the direction of the gravitational force acting on the shuttle?

The space shuttle is orbiting the Earth clockwise. Which vector shows the direction of the shuttle's instantaneous velocity?

Which diagram best shows the gravitational interaction between Earth and a satellite?

You want to launch a satellite into Earth orbit. You already know Earth’s mass, and the satellite’s mass. What additional information do you need to calculate the gravitational force that will act on it?

Why doesn't the Moon fall to the ground?

True or False: If a planet has an elliptical orbit, its orbital speed will be constant throughout its path.

The Moon has a period of 27.3 days and a mean distance of 3.9 x 105 km from its center to the center of Earth. A satellite is in orbit 3.3 x 103 km from the center of Earth. What is the satellite’s period?

Jupiter orbits the Sun at an average distance of 7.78 x1011 m. If the mass of the Sun is 1.99 x 1030 kg, calculate the period of Jupiter’s orbit.

When it comes to planets orbiting the Sun, what do the different symbols represent in the equation shown below?  $T\ =2\pi\sqrt{\frac{r^3}{Gm_s}}$
