Gravity
Introduction
This year we look beyond the effect of the the earth's gravity on objects to the concept of gravity itself: the force of attraction between objects that have mass. We will use Newton's Universal Law of Gravitation to calculate the gravitational force in a number of situations including satellite positioning. |
Interesting LinksAs always Hyperphysics has a good solid explanation of the concept of gravity

A great Video explaining Newton's thought experiment about orbiting objects being in free fall
An interesting video showing a replication of the Cavendish experiment ( the linked followup video is interesting too)
