Across
  1. 4. A force caused by air, acting in the opposite direction of a moving object.
  2. 5. to reach a conclusion using evidence and reasoning
  3. 8. speed in a given direction
  4. 9. A push or a pull that can cause the motion of an object to change. It has two important properties: strength and direction.
  5. 13. 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.
  6. 14. The process of moving or changing position.
  7. 15. the force of friction between surfaces not in motion
  8. 18. anything that has mass and takes up space
  9. 20. the force that opposes movement between touching surfaces and always acts against the direction of motion.
  10. 21. a result or change that happens because of an event or process
  11. 23. a measure of how difficult it is to change the inertia of an object
  12. 24. the speed at which the force of gravity equals air resistance
Down
  1. 1. the energy that an object has because it is moving
  2. 2. known as kinetic friction, the force of friction that affects surfaces in motion
  3. 3. When one force is stronger than the other the result is motion.
  4. 6. A force that attracts objects toward the earth. "What goes up, must come down!"
  5. 7. The speeding up of an object. The rate at which velocity changes with time
  6. 10. to apply a force
  7. 11. the combination of all of the forces acting on an object including direction of the forces
  8. 12. matter’s resistance to change in motion
  9. 14. the amount of matter that makes up an object
  10. 16. an event or process that leads to a result or change
  11. 17. the friction between surfaces, when an object, such as a wheel or a ball, rolls freely over a surface
  12. 19. the distance something travels in a certain amount of time
  13. 22. The amount of force that is applied to an object.
