  1. 3. This is another term for the air friction that slows down a sky-diver on his/her descent to earth.
  2. 7. These are used at the end of a sky-dive to increase surface area and land more gently.
  3. 10. The general push or pull on an object.
  4. 11. A force that opposes the motion of an object - example:sandpaper
  5. 12. The measure of the force of gravity on an object - example: this does change from planet to planet.
  6. 13. The unit of force in the metric system - example: this measure is on spring scales.
  7. 14. This is the world famous university that Newton studied at.
  8. 16. The amount of force that an object has is equal to its mass X _________.
  9. 19. This is the fruit most often associated with Newton and his studies on gravity.
  10. 20. The force of an object that is being lifted or carried - often related to weight.
Down
  1. 1. An element of an experiment that can be changed.
  2. 2. The force exerted by materials such as rubber bands and springs.
  3. 4. He was Newton's biggest rival in the study of gravity.
  4. 5. scale A calibrated spring used to measure forces.
  5. 6. The force of attraction between all matter - example: Earth and moon.
  6. 8. The measure of the total surface of an object - example: sky divers try to minimize this to go faster.
  7. 9. The movement or displacement of an object over a period of time - example: moving from place to place.
  8. 15. The measure of the amount of matter in a body or object - example: this doesn't change from planet to planet.
  9. 17. This is the country of Newton's birth.
  10. 18. This is the number of basic laws that Newton proposed for gravity.
