1. The force that pulls objects toward each other, keeping planets in orbit around the Sun.
2. The idea that the Sun, not the Earth, is at the center of the universe.
3. Proved orbits were elliptical, predictable and governed by laws of planetary motion
4. The study of stars, planets, and the universe beyond Earth.
6. Created the Three Laws of Motion and Universal Gravitation that supported the discoveries of Kepler.
7. A tool used by Galileo and others to observe distant objects in the sky more clearly.
10. A period when thinkers applied reason and science to understand society, government, and human nature.
11. Newton’s three rules that describe how and why objects move when forces act on them.
17. The path one object takes as it moves around another object in space.
