  1. 2. A push or pull that acts on an object
  2. 4. using force to move an object
  3. 6. the force one object applies to a second as in Newton's third law of motion
  4. 7. consists of a rigid bar that rests on a pivot point
  5. 8. arm the part of the lever you apply an input effort force
  6. 9. an inclined plane that is used as a tool for cutting or separating things
  7. 10. forces forces that do not cancel each other out when acting together on a single object
  8. 13. arm produces an output force to lift the load
  9. 15. The speed and direction of a moving object
  10. 16. a wheel with a groove in the rim
  11. 18. plane a flat, slanted surface that makes it easier to move heavy objects to higher levels

  1. 1. How fast an object's position is changing with time at any moment
  2. 2. Opposes the motion of one object moving past another
  3. 3. The tendency of an object to resist a change in its state of motion
  4. 4. and axle a large-diameter wheel rotates in a circle around a small-diameter axle
  5. 5. an inclined plane wrapped in a spiral around a cylinder or cone
  6. 11. forces forces that cancel each other out when acting together on a single object
  7. 12. A change in velocity
  8. 13. the force with which an object responds to an action as in Newton's third law of motion
  9. 14. machines devices with few moving parts that make work easier to do
