  3. A basic device that can change the amount or the direction of force, or both at once is a ___________.

  4. ___________ results when a force produces a movement in the direction of the force.

  5. Two inclined planes back-to-back form a:____________

  6. A simple machine made up of a bar and a fulcrum is a ______________

  7. A _____________ is made up of an inclined plane wrapped around a pole.

  8. To raise a heavy load, you could use a system made up of one fixed ___________ and several moveable ones.

  9. The part of a lever around which the bar moves is the_____________.

  10. A large wheel connected to a smaller wheel is a ____________.

  11. _______________ is the force that is put into a simple machine.

  12. A flat surface that has one end higher than the other is a/an ______________.

  13. In a lever, the force that is used to move the bar is called the:A. effort forceB. resulting forceC. fulcrumD. machine

  14. A wheelbarrow is a:A. wheel and axleB. leverC. pulleyD. screw

  15. When you push or pull a lever you put a force, called the ______________ on one side of the bar.A. resulting forceB. workC. effort forceD. efficiency

  16. When you turn a doorknob, you are using:A. a wheel and axleB. a pulleyC. a fulcrumD. an inclined plane

  17. A simple machine always:A. doubles lifting forceB. moves around a fixed pointC. moves an object in the same directionD. changes the size or direction of a force

  18. When you use a lever to open a can of paint, the outer rim of the can is the:A. fulcrumB. resulting forceC. effort forceD. wedge

  19. A fixed pulley is similar to a class one lever because it:A. changes the size of the effort forceB. changes the weight of the effort forceC. changes the position of its fulcrumD. changes the direction of the effort force

  20. A wheel and axle increases the:A. resulting forceB. fulcrumC. effort forceD. friction

  21. A wedge:A. reduces resulting forceB. decreases total workC. pushes things apartD. pulls objects

  22. ____________ is how well a machine changes effort into useful force.A. workB. efficiencyC. simple machineD. effort force

  23. The main difference between a wedge and an inclined plane is how they are used

  24. For a screw: the long ramp of the inclined plane is wrapped into a space that is a different height as the inclined plane but has almost no width.

  25. A screw is like an inclined plane because it requires a longer movement but it makes a larger resulting force.

  26. An inclined plane increases the amount of force needed to raise or lower an object to a given height.

  27. A wheel and axle makes your effort force into a larger resulting force.

  28. The top of the broom is the:A. effort forceB. fulcrumC. resulting forceD. simple machine

  29. The bottom of the broom is the:A. effort forceB. resulting force C. simple machineD. fulcrum

  30. The boys arm is the:A. effort forceB. resulting forceC. fulcrumD. simple machine

  31. How is a seesaw an example of a definition of work?HINT: tell what happens on a seesaw that shows it is work

  32. How is a screw like an inclined plane?
