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

• 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

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.
