Study Notes
Earth-Sun-Moon System
- The Earth, Sun, and Moon are part of a system that shows cyclic patterns of lunar phases, eclipses, and seasons.
- The model of the Earth-sun-moon system helps to describe these patterns.
Gravity in the Solar System
- Gravity plays a role in the motions within galaxies and the solar system.
- A model can be developed to describe the role of gravity in these motions.
Analyzing the Solar System
- The solar system can be analyzed to understand the relationships between the Earth, Sun, and Moon.
- This analysis can help to identify patterns and phenomena, such as lunar phases, eclipses, and seasons.
