Four moons revolve around a planet in circular orbits. Determine the period and radius of each orbit. Use the buttons on the right to start/stop the animation and step it frame-by-frame. Readouts of time and position coordinates are displayed above the buttons. |

A satellite orbits the Earth in a circular orbit. The ratio of the radius of the satellite's orbit to the radius of the Earth is given. The red dot represents an apple falling near the surface of the Earth. The distance fallen is too small in scale compared to planetary distances to see in the animation. However, the acceleration is greater than that of the satellite. The vectors represent the accelerations of the objects. |

The space shuttle orbits the Earth. The ratio of the shuttle's orbital radius to the Earth is given.
The view is looking down on a pole. The white line represents a meridian. Hence, it rotates at the same frequency as the Earth. |

Two satellites orbit the Earth in circular orbits. The ratio of the radius of each satellite's orbit to the radius of the Earth is given. The vectors represent the accelerations of the satellites. |

Earth and Mars orbit the Sun in approximately circular orbits. The ratio of the average orbital radii of the planets is given. Find the ratio of the accelerations.
(Note that in order for the Sun and planets to appear larger than points on a planetary distance scale, the sizes of the Sun and planets were scaled up relative to the orbital radii.) |

Two satellites orbit Planet Q in circular orbits. The ratios of the orbital radii and of the masses of the satellites are given. The vectors represent the gravitational accelerations and orbital velocities of the satellites. |

The green satellite orbits the Earth in a geostationary orbit. This means that the satellite orbits in the Earth's equatorial plane and always remains above the same point on the Earth. The rotation of the Earth is repesented by the white arrow, which points directly to the satellite. The elapsed time is given in both hours and seconds.
The red satellite orbits the Earth in a typical space shuttle orbit. This orbit is very close to the Earth in comparison to that of the geosynchronous satellite. A readout of the number of shuttle orbits executed is given. |
