Complete the following statement: The farther away two planets are the _______ the gravitational force between them.

• greater
• same
• zero
• less

Why is the planet moving the SLOWEST at position G?

• The planet is closest to the Sun here so it has a stronger gravitational attraction.

• The planet is closest to the Sun here so it has a weaker gravitational attraction.

• The planet is farthest from the Sun here so it has a stronger gravitational attraction.

• The planet is farthest from the Sun here so it has a weaker gravitational attraction.

The gravitational attraction between the star and the planet will be greatest at position 

• A
• B
• C
• D
