Presentation transcript:

REVIEW 1. Be able to tell what a machine does for us.

REVIEW 2. Know the three ways works can be made easier and be able to give an example of each. shovel ramp mini blind

REVIEW Know the two forces involved: Effort Force, Fe, and Resistance Force, Fr.

REVIEW 4. Understand how energy is transferred in a machine and that Wout is always smaller than Win. Wout is Work Output – the amount of work the machine puts out. Win is Work Input – the amount of work YOU put into the machine. Friction/heat means Wout is less than Win.

REVIEW 5. Define the six simple machines and be able to identify an example of each.

REVIEW 6. Describe and identify the three types of levers.

REVIEW 7. Define mechanical advantage and be able to calculate for all the simple machines both with distance and force. The number of times a machine multiplies the effort force is the mechanical advantage of the machine.

REVIEW

REVIEW 8. Define a compound machine and be able to recognize examples. A compound machine is a machine consisting of two or more simple machines operating together.
