Across
- 1. The central star of our solar system
- 4. The curved path one object takes around another due to gravity
- 6. A push or pull that can cause an object to move or stop moving
- 9. The “G” in Newton’s equation represents this fixed value
- 11. The state when gravity and inertia act together to form an orbit
- 12. A vehicle that travels beyond Earth using gravitational calculations
- 13. The amount of matter in an object
- 15. The oval shape of most planetary orbits
- 19. The tendency of an object to resist changes in motion
- 20. What scientists can do with Newton’s law to anticipate motion
- 21. The scientist who developed the Law of Universal Gravitation
- 23. A group of related parts working together (like the solar system)
Down
- 2. Describes a law that applies everywhere in the cosmos
- 3. How far apart two objects are from one another
- 5. A force directed toward the center of a circular path
- 7. A large body that orbits a star
- 8. The force of gravity acting on an object’s mass
- 10. An object that stays in orbit because of gravity and inertia
- 14. How fast an object moves in its path
- 16. The point toward which centripetal force is directed
- 17. The force that pulls objects with mass toward each other
