Exam points

  • Explain that surface gravitational field strength varies between planets because their masses, sizes or densities differ.
  • Explain weaker gravitational field strength on the Moon or Mars using its lower mass or density than Earth.
  • Use planetary data to test whether gravitational field strength × diameter² is constant.
