  1. 3. The transfer of energy when a force is applied over a distance (Work = Force × Distance).
  2. 4. Force The force exerted by the machine on the load.
  3. 6. Force The force applied to the machine by the user.
  4. 8. A toothed wheel that meshes with another gear to transfer motion and force, typically used to change the speed or direction of movement.
  5. 10. Advantage (MA) The factor by which a machine multiplies the effort force; it’s a measure of how much easier a task becomes with a simple machine.
  6. 11. Lever The load is between the effort and the fulcrum (e.g., a wheelbarrow).
  7. 14. A triangular-shaped tool that converts a force applied to its blunt end into forces perpendicular to its inclined sides (e.g., a knife or an axe).
  8. 15. The force you apply to a simple machine to overcome a load.
  9. 17. Plane A flat surface set at an angle to the horizontal, used to raise a heavy object by applying less force over a longer distance.
  10. 18. A rigid bar that rotates around a fixed point (fulcrum) to lift or move a load.
Down
  1. 1. Lever The fulcrum is between the effort and the load (e.g., a seesaw).
  2. 2. The pivot point or support about which a lever rotates.
  3. 5. Lever The effort is between the fulcrum and the load (e.g., a baseball bat).
  4. 7. The object or weight that needs to be moved or lifted using a simple machine.
  5. 9. The ratio of useful work output to the work input, often expressed as a percentage.
  6. 11. A twisted inclined plane that converts rotational force into linear force, often used to hold objects together or lift them.
  7. 12. The length over which a force is applied or the movement of the load.
  8. 13. A wheel with a groove around it that holds a rope or cable; used to change the direction of a force and lift objects.
  9. 14. and Axle A large wheel attached to a smaller axle; turning the wheel moves the axle, or vice versa, to reduce the effort needed to move a load.
  10. 16. A push or pull that can cause an object to move or change its motion.
