Lesson: Gravitational Potential Energy in a Radial FieldPhysics
In this lesson, we will learn how to calculate the gravitational potential energy between two massive objects, and how this potential energy changes as the objects change position.

Which of the following formulas correctly shows the relation between the gravitational potential energy between two objects with masses and , where their centers of mass are separated by a distance ?
The distance between the centers of mass of two massive objects is . If this distance is increased to , by what factor does the gravitational potential energy between the two objects change?
An asteroid with a mass of 3,500 kg moves from a position 40,000 km away from the center of mass of Earth to a position 22,000 km away. What is the change in the gravitational potential energy between the asteroid and Earth? Use a value of kg for the mass of Earth. Give your answer in scientific notation to two decimal places.
