What are two types of inclined planes?
200
It is a simple machine that is described as an inclined plane twisted into a spiral.
What is a screw?
300
It is a type of lever that has it's fulcrum between the load and the effort force.
What is a first-class lever?
300
It is a type of pulley where the wheel is not attached to a fixed object.

300
A wedge is a pair of inclined planes; a screw is an inclined plane twisted into a spiral.
How are wedges and screws compared to inclined planes?
300
It can be used to cut food.
What can a wedge be used for?
400
It is a type of lever that has its fulcrum at the end and the effort force in the middle.
What is a third-class lever?
400
It is the force used to do work.
What is the effort force?
400
Simple machines lose less energy to friction because they have fewer parts.
Why are simple machines more efficient?
400
It is an inclined plane wrapped around a cylinder.
What is a screw?
400
It can be used to drill a whole in wodd and metal.
What can a screw be used for?
500
It is a type of lever where the fulcrum is at the end and the load is in the middle.
What is A second-class lever?
500
It is the object being moved by a pulley.
What is the load?
500
One part is a wheel and the other part is a bar that passes through the wheel's center.
