Vocabulary
Attract
To pull objects towards each other.
Model
An object, diagram, or computer program that helps us understand something by making it simpler or easier to see.
Energy
The ability to make things move or change.
A _____ _________ can attract or repel an object at a distance.
Magnetic force
Creating a _____ of a magnetic system and defining its parts helps scientists test and explain the relationship between force and energy.
Model
Repel
To push objects aways from each other.
System
A set of interacting parts that form a complex whole.
Kinetic energy
The energy an object has because it is moving.
In a system of magnets, there is a ______ force between like poles and an ____ force between opposite poles.
Repelling/attracting
You have two magnets sitting in front of you. The opposite poles of these magnets are facing each other. How should you move the magnets to increase the potential energy?
Move them away from each other.
Magnetic pole
The two ends that all magnets have.
Magnetic field
The invisible region around a magnetic object where the repulsive and attractive forces are located.
Convert
To change from one type to another.
The pattern of magnetic field lines around attracting forces are _______ than repelling field lines around a magnet.
Different
Is the following statement true or false?
Moving a magnet against a stronger magnetic force transfers more energy to the magnetic field.
Isolate
To separate or set apart.
Magnetic field lines
A line that connects opposite magnetic poles and represents the strength and direction of the magnetic field.
Potential energy
The energy that is stored in an object or system.
A _______ _______can convert potential energy to kinetic energy.
Magnetic force
You have two magnets sitting in front of you. The same poles of the magnets are facing each other. How should you move these magnets in order to increase the potential energy?
Move them closer together.
Variable
Something that can be changed and may be measured.
Refute
To disagree and provide evidence that goes against a claim.
Transfer
To move from one object to another or one place to another.
When you move a magnet against the magnetic force this will affect its _______ _____.
Potential energy
A type of magnet in which the magnetic field is produced by an electric current.
Electromagnet
