Objectives

Students will:

  1. Define the force of gravity.
  2. Distinguish between the strong, weak, electromagnetic, and gravitational forces.
  3. State Kepler's Law of Motion and explain eccentricity, the law of orbits, the law of periods, and the law of areas.
  4. Use the Universal Law of Gravitation in problem solving.
