3. Incline Planes

3.1. A plane inclined at an angle to the horizontal

3.2. Example: Switchback Roads, hills, wedges

3.3. They are included in simple machines because they include simple machines

4. Wedge

4.1. A thin wedge of a given length has a greater ideal mechanical advantage than a thick wedge of the same length

4.2. Examples: The blade of a ax, knife, or scissors

4.3. Related to a simple machine because they are a simple machine and are included in a simple machine

4.4. A V-Shaped object whose sides are two inclined planes sloped together

5. Screw

5.1. Is an inclined plane between a cylinder

5.2. Screws with threads that are closer together have a greater ideal mechanical advantage

5.3. Examples: Used in drills, light bulbs, bottle caps, ball point pens

5.4. Is a simple machine and is included in a simple machine

5.5. Metal wrapped up in a metal coil

6. Pulley

6.1. A simple machine that consists of a rope that fits into a groove in a wheel

6.2. Examples: Pulley used to raise and lower flags, make a ladder shorter or longer, used for physical therapy

6.3. Related to a simple machine because it can be found within a simple machine and is a simple machine it's self

7. Work

7.1. Product of force and distance. Requires change in position. Has to move in direction of the force being applied.

7.2. Work Formula: W= Force * Distance

7.3. Units: Joules

7.4. Examples: Moving a desk, throwing a ball, Picking up a book

7.5. They relate to a simple machine because work allows you to use simple machines

8. Power

8.1. How fast you are doing work

8.2. Power Formula: Work/Time

8.3. Units: Watts

8.4. Included with simple machines because of how fast you are using said simple machines

8.5. Examples: How long it takes to move a desk, how long it takes to throw a ball, How long it takes to Pick up a book

9. Mechanical Advantage

9.1. Tells how much a machine multiplies force or increases distance

9.2. Ideal Mechanical Advantage Formula: Output Force/ Input Force

9.2.1. Actual Mechanical Advantage Formula: Input Distance/ Output Distance

9.3. Both Ideal and Actual Mechanical Advantage have no units

9.4. Related to a simple machine because a simple machine is considered a mechanical advantage by helping get work done more efficiently and faster.

9.5. Examples: Broom, and screwdriver help get work done more efficiently while including other simple machines

10. 2nd Class Levers

10.1. Wheelbarrow

10.2. They are a level in simple machines

10.3. A level of simple machines to organize them based on where the force is located

11. Wheel and Axle

11.1. A simple machine that consists of two disks or cylinders, each with a different radius.

11.2. To calculate the ideal mechanical advantage of the wheel and axle you need to divide the radius where the input force is exerted by the radius or diamaterer where the output force is exerterd

11.3. They relate to simple machines because they are a simple machine, and included in simple machines

11.4. Examples: Found on cars, bikes, skateboard
