Answer 1

Here's the matching of the key ideas/scientists/terms of orbital motion with their correct descriptions:

1. Geocentricism - Ptolemy, and others, idea that suggests the Earth is at the center of the universe and all other planets orbit it.
2. Orbit - The Earth moves in a(n) _____ or path around the Sun.
3. Orbital period - The moon takes 278 days to encircle the Earth. This amount of time is known as its _____.
4. Gravity - What keeps our feet planted solidly on Planet Earth.
5. Heliocentricism - Copernicus' model that the Sun is at the center of the Universe.
6. Galileo - The scientist whose invention of the telescope helped to support Heliocentricism.
7. Brahe - Kepler's boss and mentor who collected a large amount of astronomical data used by later astronomers.
8. Newton - Scientist who coined the Universal Law of Gravitation.
9. Kepler's 2nd Law - Another name for "The Law of Areas" where two parts of an orbit move in the same times and sweep out equal areas.
10. Inertia - While the Earth is locked into orbit with the Sun's gravity, it continues moving forward due to ______.
11. Kepler's 1st Law - The planet moves in ellipses with the Sun at one of the Foci.
12. Perihelion - Area of orbit closest to the Sun, and moves fastest, is called the _____.
13. Aphelion - The area of orbit farthest from the Sun, and moves slowest, is called the ____.
14. Kepler's 3rd Law - The Earth's distance from the Sun and orbital periods are proportional to that of Jupiter's, due to _____.
15. Mass - According to Newton, Force increases when the ____ of an object increases.

This should help you understand the key concepts and their descriptions in the context of orbital motion!
