These are the kinds of questions viewers will be prepared to discuss after screening. This definitive film is unique in its carefully duplicated experiments of Cavendish and Boys that clearly illustrate the relationships of mass and distance to the force of gravity., Demonstrates magnetic, electrostatic, and gravitational forces. Duplicates the experiments of Cavendish and Boys which indicate the existence of gravity. Discusses gravity in relation to the Earth and the solar system., NOTE: Two (or more) records have been merged together to create this data.
