SPI 0807.12.6 (Gravity-Celestial
Motion)
Examine the picture shown above. Notice that it is showing the orbital
path of the Moon as it moves around the Earth. Identify this motion
a. | This motion is called revolution | b. | The Moon orbits around the Sun at the speed of
light. | c. | The Moon’s motion in this example is called rotation. | d. | The diagram above is
showing how the Moon spins around the Earth. |

SPI 0807.12.6 (Gravity-Celestial
Motion)
A student drew a
diagram showing Earth at four different points in its orbit around the Sun. The student drew arrows
to represent the direction of the gravitational force of the Sun pulling on our
planet.
Which arrow did the
student draw incorrectly?

SPI 0807.12.6 (Gravity-Celestial
Motion)
Look at the diagram above showing the motion of planet Earth. Like all
the other planets in our solar system, due to gravity, Earth spins on its axis. Identify this
motion
a. | This motion is called revolution. | b. | The diagram above is showing how the Earth
orbits the Sun | c. | The diagram above is showing how the Earth revolves around the Sun.
| d. | This motion is called rotation. |

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. | The rings are orbiting (revolution) around Saturn due to gravity. | b. | These rings do not
have any motion. They are static. | c. | Saturn’s rings are rotating along their
own axis but not revolving around the planet | d. | This planet’s rings are moving upward and
downwards due to the solar wind. |

SPI 0807.12.6 (Gravity-Celestial
Motion)
Based on what you see in the diagram above, what is the best
description of the motion being displayed?
a. | Orbit is when one object in space such as a planet spins on its own axis.
| b. | In this diagram the Earth is demonstrating lateral and horizontal motion around the
Sun. | c. | Revolution is when one object travels around another object in a roughly circular
path. | d. | Rotation is when one object travels around another object in a roughly circular
path. |

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