Objectives
1. Explain how teh speed of a satellite in circular orbit around the Earth is related to
the distance an object falls in the first second due to gravity.
14.2 Circular Orbits
2. Explain why the force of gravity does not cause a change in the speed of a satellite
in circular orbit.
14.3 Elliptical Orbits
3. Describe how the speed of a satellite changes for different portions of an
elliptical orbit.
14.4 Energy Conversation and Satellite Motion
4. Apply the energy conservation law to describe changes in the potential and
kinetic energies of a satellite for different portions of an elliptical orbit.
14.5 Escape Speed
5. Describe what is meant by escape speed.
Misconceptions
Note: The following statements are all FALSE!!!
1. Satellites are beyond the main pull of a planets gravitational field.
2. Satellites are held up by centrifugal force.
