  2. 3. The speed of a reindeer sleigh could be a __________ variable in an experiment that examines changes in the number of deer pulling the sleigh.
  3. 6. Santa may have a magic sleigh and reindeer, but even they must deal with air _________ as they travel through the Earth's atmosphere.
  4. 7. If the peak forces in a collision _______ the elastic limit of an object/material damage will occur to that object.
  5. 9. While it is still spinning, the total forces acting on a dredel are greater then the force of __________, which would cause it to fall down otherwise.
  6. 13. When the force applied to an object is greater than its __________ ___________ it will cause permanent deformation.
  7. 14. A free-body ________ is used to communicate information about the strength and direction of forces acting on an object.
  8. 19. The amount of sugar in a cookie recipe is an ________ variable that will affect the sweetness of the cookie.
  9. 20. When everyone sings the Welcome Song at Lumina, _______ is one kind of collision that is very much not allowed by Mr. Barnard.
  10. 21. The consistent mass of a large holiday elf sitting in a reindeer sleigh would be a good ________ variable in experiment investigating changes in speed to the sleigh and timing of the delivery of presents.
  11. 22. While a dredel is still spinning on a table, _________ force from the table pushes up against the dredel in the opposite direction of a force that wants to pull it down.

  1. 1. When a child excited tears apart the paper of a present and throws it all around, the flying pieces of paper have _________ energy because they are in motion.
  2. 4. 54,000 _____ is the elastic limit of steel. This is the highest amount of force that can be applied to steel where material will still return to its original shape.
  3. 5. A change in shape due to a force is _____.
  4. 8. The ________ of santa's reindeer has a greater effect on the kinetic energy of his sleigh than their mass.
  5. 10. No matter how many cookies Mrs. Clause bakes, the peak forces in a collision between Santa and a tiny elf will always be ________. Even if the elf is running very fast.
  6. 11. Damage is a synonym for __________ deformation. This is when force applied is so great that it does not return to its original shape after the force is removed.
  7. 12. Permanent shape change to an object or material is _________.
  8. 15. When presents are sitting under a tree or on top of a table and not moving, they have _________ energy. This is the energy of their position.
  9. 16. The maximum forces that occur equally on two ornaments in collision are called ________ forces.
  10. 17. When an object changes shape due to a force and returns to its original shape after the force is removed this is ___________ deformation.
  11. 18. Presents falling down a chimney have kinetic energy because they are in ________.
  12. 20. The jingle of bells is caused by the ________ of two objects, the small hammer inside of the bell and material around it.
