Explain the conditions required for a satellite to achieve a geostationary orbit.
Model answer
What a good answer should say
- For a satellite to be in a geostationary orbit, it must orbit the Earth at an altitude of approximately 35,786 kilometers above the equator, with an orbital period equal to the Earth's rotation period of 24 hours.
- This allows the satellite to remain fixed relative to a point on the Earth's surface.
Explanation
Why this works
This answer is strong because it accurately describes the specific altitude and orbital period necessary for geostationary orbits, testing the understanding of gravitational forces and orbital mechanics.
