In this chapter you will learn how to: describe a gravitational field as a field of force and define gravitational field strength g represent a gravitational field using field lines understand the meaning of centre of mass and use the concept in problems involving uniform spheres recall and use Newton’s law of gravitation solve problems involving the gravitational field strength of a uniform field and the field of a point mass understand how the gravitational potential energy, , of two point masses is a consequence of gravitational potential define and solve problems involving gravitational potential analyse circular orbits in an inverse square law field, including geostationary orbits.
