Gravity for Geodesy I: Foundations

Gravity for Geodesy I: Foundations
  1. Define the basic properties of gravitation.
  2. Explain the properties of gravitation near a large mass such as a planet.
  3. Explain the relationship between gravitation and gravity.
  4. Identify density, altitude, and latitude as the three key influencing factors on gravity.
  5. Explain how gravity’s magnitude varies with latitude.
  6. Show how gravity’s magnitude decreases with altitude.
  7. Give examples of high and low density features of Earth and the resulting changes in gravity.
  8. Describe the impact of mass movement on gravity.
  9. Identify the signals that gravimeters measure.
