I discovered that the wedge is easier to brake a rock. The lever was the easiest, because just move what you are using to make it work. The relationship is they both work together.
i discovered that they are very helpful. They help you move something very heavy to a spot. The long helps more then the short. The short one would help if you had something light to move. The different lengths would help.

Lever YAY!!
The fulcrum is the biggest part of the lever, it is the toast with the jam, the straw to the berry, and so on. When the fulcrum is closer to you it is harder to move something and when it is farther away it gets easier and easier. The longer the incline plane is the easier it is to get up and the shorter it is the harder it is. The weather and the height of the ramp are the factors that might affect it.
