2 cards from this section. Quick, good the night before a test.
What is kinetic energy?
Think about how fast an object is moving.
What is the formula for potential energy of a satellite?
Remember the role of distance from Earth's center.
What is the total energy of a satellite in a stable orbit?
Consider what happens to energy when objects escape gravitational fields.
True or False: Kinetic energy can be negative.
Think about the definition and formula for kinetic energy.
A satellite with a mass of 200 kg is in a circular orbit 500 km above the Earth. Calculate the K.E, P.E, and T.E of the satellite.
Use known Earth constants: G and radius for calculations.
Compare the energy dynamics of an artificial satellite in a low Earth orbit versus one in geostationary orbit. Explain the implications of these differences.
Consider the height of each orbit and their speeds.
