This unit builds student understanding of the Law of Universal Gravitation starting with individual masslets. Building on the belief in the gravitational force between small objects established in the earlier Gravitational Force I unit, the argument is developed for equal and opposite gravitational forces. In order to ensure that students grasp the significance of the equal and opposite force pattern, we consider examples in the three domains of gravitational forces from Gravitational Force I.Read More
