Lever+Lab+Questions

Which lever class has the fulcrum between the effort and resistance?
 * Questions**:
 * First Class Lever**

Which lever class has the effort between the fulcrum and resistance?
 * Third Class Lever**

Would a hammer pulling a nail be in the same class as a hammer pounding a nail? Explain your answer.
 * No, because the positions of the fulcrum, effort force and resistance force will change**.

Give an example of a lever other than the ones already so designated in this investigation that would be in different classes, depending on its use. First Class Lever: **Crowbar** Second Class Lever: **Wheelbarrow Third Class Lever: Broom**

True or False: A lever that provides an easier effort force cannot, at the same time, also shorten your distance.
 * True**

True or False: A lever that provides an easier effort force cannot, at the same time, also change direction.
 * True**

True or False: A lever that shortens your distance can also change direction.
 * False**

For the levers which you found provided an easier effort force, was the fulcrum closer to the effort or to the resistance, or were the distances equal?
 * Fulcrum closer to the resistance**

For the levers which you found shortened your distance, was the fulcrum closer to the effort or to the resistance, or were the distances equal?
 * Closer to the resistance force**

What is the relationship between lever class and mechanical advantage
 * Mechanical advantage is used in assessing the performance of a machine. Levers can give you a mechanical advantage. Simple machines give you mechanical advantage.**
