  1. 2. the amount of matter that makes up an object
  2. 5. to reach a conclusion using evidence and reasoning
  3. 10. a result or change that happens because of an event or process
  4. 12. push or a pull that can cause the motion of an object to change. It has two important properties: strength and direction.
  5. 13. the speed at which the force of gravity equals air resistance
  6. 14. the combination of all of the forces acting on an object including direction of the forces
  7. 16. speed in a given direction
  8. 17. The process of moving or changing position.
  9. 18. an event or process that leads to a result or change
  10. 20. A force that attracts objects toward the earth. "What goes up, must come down!"
  11. 21. a measure of how difficult it is to change the inertia of an object
  12. 22. When two equal forces act in opposite directions the result is that the forces are balanced and there is no motion. The forces cancel each other out.
Down
  1. 1. the energy that an object has because it is moving
  2. 3. The speeding up of an object. The rate at which velocity changes with time
  3. 4. the force that opposes movement between touching surfaces and always acts against the direction of motion.
  4. 6. to apply a force
  5. 7. The amount of force that is applied to an object.
  6. 8. anything that has mass and takes up space
  7. 9. the distance something travels in a certain amount of time
  8. 11. matter’s resistance to change in motion
  9. 15. A force caused by air, acting in the opposite direction of a moving object.
  10. 19. When one force is stronger than the other the result is motion.
