Hello. This question is incomplete. The full question
"Which statements accurately describe satellite motion? Check all that apply: Gravity is the only force acting on a satellite. Inertia is the only cause of a satellite’s circular motion. Air resistance prevents satellites from staying in orbit for very long. Circular orbits result from the interaction between gravity and inertia. Gravity provides the centripetal force for satellites. Satellites are in free fall around Earth or other central objects."
Answer:
- Gravity is the only force acting on a satellite.
- Circular orbits result from the interaction between gravity and inertia.
- Gravity provides the centripetal force for satellites.
- Satellites are in free fall around Earth or other central objects.
Step-by-step explanation:
Satellites are bodies that orbit around a celestial body. They can be classified as natural (celestial stars that orbit around a planet, for example, the Moon) and artificial (objects made by man and placed in orbit of a celestial body). There are several artificial satellites around our planet and with different functions, such as communication, meteorological, military and astronomical satellites.
The movement of satellites around a planet obeys Kepler's Laws and Universal Gravitation. About this movement we can say that:
- Gravity is the only force acting on a satellite.
- Circular orbits result from the interaction between gravity and inertia.
- Gravity provides the centripetal force for satellites.
- Satellites are in free fall around Earth or other central objects.
