  3. 5. Force used to cause movement
  4. 6. The force of attraction that exists between any two bodies in the Universe that have mass
  5. 7. An independent variable is the factor that is changed or controlled in an experiment to test its effects on the dependent variable.
  6. 10. Acceleration is the rate at which an object's speed or direction changes over time
  7. 13. Force between objects that are touching
  8. 15. The maximum constant speed reached by a falling body when the force of gravity pulling it down is balanced by the air resistance pushing against it
