Inclined planes do this to the amount of force you need.

What is decrease?

100

A flag pole is an example of this.

What is a fixed pulley?

100

Where do you operate a wheel and axle in order to gain speed?

What is the axle?

100

This place is where you apply your force when using a lever.

What is the effort?

100

This is the formula for work.

What is Work = F x D

200

This is always above 1 for a ramp.

What is mechanical advantage?

200
These are 2 examples of fixed pulleys.

What are flag poles and blinds?  Others excepted too!

200
Wheel and axles often decrease this when they are placed on the bottom of objects.

What is friction?

200

Second class levers have this type of number is the mechanical advantage.

What is above 1?

200

These are found on the right side of a chemical equation.

What are products?

300

Of D and E, located on the board, this ramp offers the greatest mechanical advantage.

What is D?

300

This is the mechanical advantage of the pulley system on the left.

What is 3?

300

This is the mechanical advantage of G when operated at the axle.

What is 1/8?

300

The mechanical advantage if lever B is used by applying the effort on the right side.

What is 1/2?

300

These are the 2 ways to find MA.

What are D/D and F/F?

400

Two things that inclined planes cannot do for you.

What are decrease or lessen the work and do the work for you?

400

This is always true if you move farther than an object does when using a pulley system.

What is MA is above 1 and force needed is less?

400

This is the mechanical advantage of H, when operated at the wheel?

What is 10?

400

This the the class of lever C found on the board.

What is 2nd Class?

400

These 2 simple machines are also inclined planes.

What are wedges and screws?

500
This is used to find the distance of the hypotenuse on a right triangle.

What is the Pythagorean theorem?

500

This pulley type would have same mechanical advantage as the middle system.

What is a movable pulley?

500

These are 2 wheel and axles found that are operated at the axle.

What are a top, a fan, etc?

500
In this situation a lever may have a MA of exactly 1.
What is a first class lever where the effort and load arms are the same length?
500

This is the inclined plane portion of a screw.

What are threads?
