Description

Overview of the essential ideas for this topic:

6.1: A force applied perpendicular to its displacement can result in circular motion.

6.2: The Newtonian idea of gravitational force acting between two spherical bodies and the laws of mechanics create a model that can be used to calculate the motion of planets.
