Describe the relationship between the orbital height and the speed of the satellite. suggest an explanation for this behavior.
Answers
Answer:
The orbital velocity of the satellite depends on its altitude above Earth. The nearer to Earth, the faster the required orbital velocity. At an altitude of 124 miles (200 kilometers), the required orbital velocity is a little more than 17,000 mph (about 27,400 kph).
Explanation:
The speed of an object's orbit around earth depends on the object's axis - find out how here. Objects captured by the Earth's gravitation typically have elliptical orbits. The mean orbital speed of the object depends only on the Earth's mass and the semi-major axis (half the longest diameter) of the object's orbit.
The higher the orbit (larger distance between the planet and the satellite), the less speed is required to prevent the satellite from falling out of its orbit and crashing into the planet. The nearer the orbit, the faster it must move to ensure that it does not crash into the planet.
Orbital speed is the speed needed to achieve the balance between gravity's pull on the satellite and the inertia of the satellite's motion. This is approximately 27,359 km per hour at an altitude of 242 km. Without gravity, the inertia of the satellite will carry it off into space.
