Big Ideas
  • The gravitational force between two objects depends on both their masses and the distance between their centers, as described by Newton's law of universal gravitation.
  • Understanding and applying the law of universal gravitation allows us to predict the behavior of objects in both linear and orbiting systems, such as planets and satellites.
