Across
  1. 2. is an incline plane. The indent that spirals around the core is called the thread. This provides a turning effect of a force.
  2. 3. calculated by dividing the size of the load by the size of the effort.
  3. 5. is an incline plane that moves through an object and changes the direction of a downward force to a sideway force.
  4. 6. A machine is a device that makes a physical task easier.
  5. 8. is a special type of wheel and axle that makes it easier for you to lift a load. The wheel has a groove around it so that a rope or cable can be passed over or under it.
  6. 9. This is when you apply a force to a small object (pedals of a bike) and the force is magnified on a larger object (the wheel of a bike)
Down
  1. 1. this is when a small force moves are larger load.
  2. 4. is used to move a heavy object up an incline plane.
  3. 5. a lever is fixed at one end and rotated
  4. 7. Has 3 components (effort, load and fulcrum)
