SPI 0807.12.6 (Gravity-Celestial
Motion)
Due
to gravity the Moon orbits the Earth. If somehow the gravitation force from these two celestial
objects was removed, what would happen to the Moon?
a. | The Moon would continue to revolve around the Earth, but its speed would be
slower | b. | The Moon would fly off into space in a straight line away from the
Earth | c. | Both celestial objects would immediately fall into the Sun and be
destroyed. |

SPI 0807.12.6 (Gravity-Celestial
Motion)
What motion do all three
of the celestial objects shown above have in common?
a. | They all spin due to the force of electromagnetism | b. | They all move
diagonally across the solar system. | c. | They all rotate due to the force of
gravity |

Motion)
Saturn’s Rings |  Saturn | |
Look at the diagram of Saturn displayed above. Note that Saturn has
rings around it. These rings are made of small rocks, ice, and cosmic dust that are held in place by
gravity. Identify the motion of these rings.
a. | This planet’s rings are moving upward and downwards due to the solar wind.
| b. | These rings do not have any motion. They are static. | c. | The rings are
orbiting (revolution) around Saturn due to gravity. |
