  1. 4. Forces that require contact between two objects or substances.
  2. 5. One of the two components of forces, it is the size of strength.
  3. 7. This is a measure of speed at a given instance. For example, if you are stopped at a traffic light this would be 0.
  4. 11. When a force is applied to an object, the purpose is to create this.
  5. 14. The rate of cahnge in velocity.
  6. 15. This type of force is the upward force exerted on objects in a fluid.
  7. 17. A sliding force that can break an object apart.
  8. 22. One of the four fundamental forces, this force is found within the atomic nucleus and is responsible for certain types of radioactivity.
  9. 24. The splitting of the nucleus of an atom.
  10. 26. One of the two components of forces, it describes which way the force is going.
Down
  1. 1. The force that resists motion in two objects.
  2. 2. The force that results from pushing or squeezing an object.
  3. 3. This is the result of unbalanced forces.
  4. 6. One of the four fundamental forces, this force deals with electricity and magnets.
  5. 8. One of the four fundamental forces, this force causes a ball to fall to the ground when thrown in the air.
  6. 9. Speed with direction.
  7. 10. The device used to measure the force exerted on something.
  8. 12. This type of force pulls a stretched object back to its regular shape.
  9. 13. This type of force results from a pull exerted on an object.
  10. 16. All forces added together.
  11. 18. The rate at which an object moves. It's equation is distance/time.
  12. 19. The forces that do not require contact.
  13. 20. A push or a pull
  14. 21. This force is the strongest of the four basic noncontact forces, it is the force that holds protons and neutrons in the nucleus of an atom.
  15. 23. The amount of force applied to an object is measured in this.
  16. 25. A point against which the position of an object is measured.
