Simple Machines

We talked about simple machines! We even played around with partners to make different kinds of pulleys that distributed the weight in different ways.

Notes taken:

1. Wedge
2. ****Gear-not always included in the list
3. Inclined plane
4. lever
5. Screw
6. Wheel and axle
7. Pulley
1. the fixed pulley changes the direction of the force
2. The moveable pully cute the work in half but double the amount of line must be used

1. Work-Force through distance=work
2. There are three levels of a lever
1. 1st class
2. 2nd class
3. 3rd class
3. Magnets only work on certain meta;-mostly only iron ore

Here are the sheet that Mr. Martin passed out to the class.
