Universal Gravitation (1961)

The film discusses the law of universal gravitation, primarily based on Sir Isaac Newton’s work. It explains how gravity acts as a force that attracts objects towards each other, using a fictional planet, Planet X, to illustrate these concepts. The narrative contrasts heliocentric and geocentric perspectives, demonstrating the relative nature of motion and the importance of inertial frames of reference. It also describes experiments with satellites to confirm the inverse square law of gravitational attraction and the mass of celestial bodies. Ultimately, it highlights Newton’s contributions to understanding gravity and the mechanics of our solar system.
