Across
  1. 1. A force exerted toward the center of a curved path.
  2. 3. A machine that does work with only one movement of the machine.
  3. 4. Energy that is stored.
  4. 5. The tendency of an object to resist change in its motion.
  5. 6. A set of forces acting on an object so that the net force does not equal 0 and the object is accelerating in the direction of the net force.
  6. 10. The support force exerted by a surface against an object resting on it. It acts
  7. 12. A pulling force transferred to an object through a medium such as a rope or cable.
  8. 17. The maximum speed an object falling through a “fluid” (like air) can reach.
  9. 20. A ratio showing the output force compared with the input force.
Down
  1. 1. A combination of two or more simple machines.
  2. 2. Energy due to motion.
  3. 7. Force The sum of all the forces acting on an object.
  4. 8. The force that opposes the sliding motion of two surfaces that are touching.
  5. 9. A device that changes the force or increases motion from work.
  6. 11. to the surface.
  7. 13. The ability to cause change.
  8. 14. A resistive force exerted by a fluid (such as air or water) that opposes the motion of an object moving through it.
  9. 15. Forces A set of forces acting on an object so that the net force equals 0 and the object is not accelerating in any direction.
  10. 16. The measure of energy transfer that occurs when an object is moved over a distance by a force.
  11. 18. A push or a pull on an object.
  12. 19. The attractive force between any two objects that depends on the masses of the two objects and the distance between them.
