After completing the lesson, a learner will be able to do the following:
  • Define gravitational potential energy.
  • Define an equipotential (level) surface.
  • Describe how level surfaces aren’t parallel and their spacing changes.
  • Explain the impact of gravity variations in determining flood plains.
  • Explain how orthometric correction is applied to leveling measurements.
  • Explain methods for measuring gravity.
  • Define the geoid and its relationship to gravity and sea level.
  • Explain why models of the geoid are necessary.
  • Give examples of places where airborne gravity can collect better data than other gravity methods.
  • Explain the goals of GRAV-D program.
  • Explain that the gravity field varies over time.
