You probably recall this diagram of the Global Positioning System satellites. In the previous two lessons, you've explored the physics behind their orbits and had the opportunity to learn more about the GPS network and its essential nature for today's navigation and defense.
In this lesson, we'll investigate the energy requirements for putting these satellites into their orbits. Just how much energy does it take?
And how much energy does it take in order to send a satellite completely out of orbit around the earth? Around the sun?
In this lesson, we'll answer these questions and more.
