Explanation:
To answer the question, we need to understand the basic principles of satellite motion. Here is a detailed explanation:
1. Introduction to artificial satellites:
- Artificial satellites are objects that are intentionally placed into orbit around the Earth.
- They are used for various purposes such as communication, weather monitoring, navigation, scientific research, and military surveillance.
2. Satellite motion:
- Satellites move in a specific path called an orbit around the Earth.
- The motion of a satellite is determined by the gravitational force between the satellite and the Earth.
- The satellite moves in a curved path due to the balance between its forward motion and the gravitational force pulling it towards the Earth.
3. Types of satellite orbits:
- There are different types of satellite orbits, including geostationary, polar, and elliptical orbits.
- Geostationary satellites orbit in a fixed position above the Earth's equator and appear to be stationary from the ground.
- Polar satellites orbit the Earth from pole to pole, providing global coverage.
- Elliptical orbits have a more elongated shape and vary in their distance from the Earth.
4. Direction of satellite motion:
- Satellites revolve around the Earth in a fixed direction.
- The direction of satellite motion is determined by the initial velocity and the orbit it is placed in.
- Once a satellite is launched into its designated orbit, its motion will continue in the same direction unless influenced by external forces.
5. Conclusion:
- In conclusion, artificial satellites revolve around the Earth in a fixed direction.
- The direction is determined by the initial velocity and the specific orbit the satellite is placed in.
- This fixed direction allows satellites to perform their intended functions effectively, such as providing continuous communication coverage or collecting data over specific regions.
