  1. 1. The size and distance of one object relative to another.
  2. 4. The force that attracts objects to the center of Earth or to the center of any other physical object with mass such as the Sun.
  3. 5. The motion pathway of a solar system object through space in a curved shape around another object.
  4. 8. Rocky bodies orbiting the Sun, mostly between Mars and Jupiter.
  5. 12. An attractive force between two objects.
  6. 13. The forces caused by one surface or object rubbing against another as they move past each other.
  7. 15. Small piece of rock in the solar system

  1. 2. Friction forces that air particles apply against a moving object.
  2. 3. A very spread out collection of cloud, gas, and dust in outer space.
  3. 6. A property of matter that causes objects to continue in a state of motion or rest unless changed by a force.
  4. 7. The motion pathway determined by the forces of gravity of objects in space.
  5. 9. A system of solar systems, stars, gas, dust, and other matter.
  6. 10. The lack of any air particles in a volume.
  7. 11. A push or a pull on an object.
  8. 14. Small icy object orbiting the Sun that may have a long “tail” or halo when closer to the Sun.
