Gravitational Mass

Mr. Andersen explains gravitational mass, contrasting it with inertial mass. He discusses Newton's insights on gravitational force, which depends on mass and distance. The video covers measuring gravitational mass using a balance and explores how this measurement remains consistent on the Moon. Historical experiments by Galileo and Newton are highlighted, demonstrating consistent acceleration in free fall. The video concludes with a demonstration from the Apollo 15 mission, confirming Galileo's findings in a vacuum.
