Description: The relationship of mass and distance to the force of gravity are explored by careful duplicating of Cavendish’s and Boy’s experiments. Understanding gravity helps us to explain the movements of the planets and the changes in weight of astronauts as they land on the moon. Suitable for upper secondary levels.

Complete Record: Why does an astronaut who weighs 170 pounds on earth weigh only 27 pounds on the moon? Would you weigh the same on a high mountain as you do at the seashore? 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.
