Paragraph: (Science-textbook/science-g5-1.txt)
Sent 1: Magnets are able to place a force on certain materials.
Sent 2: This force is called a magnetic force.
Sent 3: The force a magnet exerts is a little different from the forces you may normally think about.
Sent 4: You exert a force on a book when you lift it.
Sent 5: You also exert a force on the pedals of your bicycle.
Sent 6: In both those cases, those forces cause a change.
Sent 7: The change you see in both these cases is called motion.
Sent 8: Magnets, too, can produce change.
Sent 9: They can produce motion just like you do.
Sent 10: Unlike you, magnets do not have to touch something to exert a force.
Sent 11: A magnetic force is exerted over a distance.
Sent 12: Thats right, a magnet can push or pull certain items without ever touching them.
Sent 13: Thats how the maglev train works.
Sent 14: Do you know another type of force that does not require objects to touch?
Sent 15: These forces are known as non-contact forces.
Sent 16: Another type of non-contact force you may be familiar with is gravity.
Sent 17: Gravity too can cause changes in motion.
Sent 18: Gravity holds our moon in orbit without touching it.

Question: The force that holds our moon in place, is an example of what type of force? (false/0)

Question: What is another type of force that does not require objects to touch? (false/1)

Question: How are magnetic forces different from other forces? (false/2)

They produce force without touching
Pretty much the same; the all use touching
Magnets produce force by touching
Other forces cause a change called motion
Magnetic force can produce motion without actual contact with certain materials

Question: Can magnets produce motion? (true/3)

No, they can only produce change
No
Yes, they can

Question: What kind of force is used to move a maglev train? (true/4)

Non-contact force
Physical force
The maglev train can push or pull certain items without ever touching them
Magnetic force

Question: The force magnets put on certain materials is called what? (true/5)

Magnets do not put force on certain materials
Magnetic Force
Wind force
contact force

Question: What is a magnetic force? (true/6)

Force exerted by wind
The force a magnet places on a material
The force Magnets able to place on certain materials

Question: Does a magnet have to be touching an object to assert push or pull? (false/7)

Yes, contact is important for the magnetic forces
No, it doesn't have to touch certain object to assert push or pull
No
Yes
No it is exerted over a distance

Question: What are a few examples of non-contact force? (false/8)

Question: The force you exert on your bike pedals that causes change is called what? (true/9)

Question: Name a few types of non contact force (true/10)

Question: What can magnets do? (false/11)

Magnets are able to place a force on certain materials
Magnets can produce change on materials
Magnets can touch and produce force
They can place a force on certain materials called a magnetic force

Question: How do magnets produce change? (true/12)

They produce change just like humans do
They produce change by exerting a force over a distance
By touching things
Magnets do not have to touch something to exert a force
They can produce motion

Question: What are non contact forces? (true/13)

Force exerted by touching
Forces exerted without touching anything
Non-contact forces are gravity and maglev train
Force that does not require objects to touch
Non-contact forces are forces that do not require touching to produce a change or motion

Question: How do magnets exert force? (false/14)

They exert force by producing a change
By touching anything
They exert force without coming into contact with certain material
A magnetic force is exerted over a distance
A magnetic force is exerted over a distance and can push or pull certain items without ever touching them

Question: What is the difference between magnetic force and the force a human uses to move things? (true/15)

Magnets do not have to touch something to exert force, it is extended over a distance
The difference lies in exertion. Unlike humans, magnets do not have to touch something to exert a force
Magnets touch something
Magnets do not have to touch something to exert a force
The change magnet produce
