Earth Science: Gravity and Objects

by Texas Instruments - Simulation Lesson


  • Students will investigate and discover relationships among distance, mass, and gravity.
  • Students will explore how the distance of each planet from the Sun as well as the mass of each planet affects the gravitational force between the planet and the Sun.


  • law of universal gravitation
  • inverse square law
  • revolve
  • astronomical unit

About the Lesson

In this lesson, students will investigate relationships among distance, mass, and gravity and explore gravitational forces between planets and the Sun.

 As a result, students will:

  • Understand how the distance between two objects is related to the force of gravity between them.
  • Determine whether mass or distance has a greater effect on the gravity between two objects.
