Yes
100
What is a wedge used for?
To seperate two objects.
100
What is an inclined plane?
Any slope or ramp.
100

What is an example of a wheel and Axel
{multiple options}
200
What is a wedge made of?(hint:Has to do with another simple machine)
Made of two incline planes.

How is a wheel and axle helpful?
{multiple options}
300
Name one difference between a wedge and an inclined plane
1.How it's used 2.Inclined plane doesn't move, wedge does move
300
How is an inclined plane used?
An object is pushed up a slope/ramp.
300
What does a fixed pulley do?
Change direction of force.
400
What happens if the fulcrum is moved back{what happens to your ability to lift the weight}?
Weight becomes harder to lift.
400
How does size of wheel effect the mechanical advantage?
Bigger wheels give you more mechanical advantage.
400
What effects how well the wedge works?
The angle of the point if the wedge.
400
Does making the ramp longer increase or decrease how hard it is to push an object?
Decrease
400
What is a moveable pulley?
Pulley that moves.
500
What is mechanical advantage?
How much a machine helps you do work.
500
How does the axle effect mechanical advantage?
Axles make the wheels spin more than if it was not there, or, Bigger axels create more mechanical advantage.
500
Which works better a thin wedge or a thick wedge?
Thin wedge
500
Compared to lifting the object, there is less work needed when using an inclined plane. True or False?
False
500
Which works better a fixed pulley or a moveable pulley?
Moveable pulley.
