Lecture 15: Universal gravitation

Objectives: In this lecture, students will learn to
  • state Kepler's Laws of planetary motion
  • formulate Newton's law of universal gravitation
  • relate the free-fall acceleration to mass and radius of a celestial body
  • explain satellite motion in terms of circular motion under the influence of gravity
  • derive Kepler's 3rd law for a circular orbit
