100
This term describes a "push" force between two of the same magnetic poles.
Repulsion/Repel
100
When two magnets with attractive forces are moved further apart, this is what happens to the amount of energy that can be transferred.
Increases
100
In an electromagnet, the magnetic field is only present when this is flowing through the coil of wire.
Electric Current/Electricity
100
In a collision, how many object deform?
All in the collision
100
What needs to be created in order for a sound to be created?
Vibration
200
This term describes a "pull" force between two opposite magnetic poles.
Attraction/Attract
200
Magnetic forces move out of or away from this pole and into or toward the other.
North pole
200
What materials do you need to create an electromagnet?
A power source (battery)
A coil (wire)
200
Forces are always what?
Forces always come in equal strength and opposite directions.
200
Does sound need a medium to transfer energy?
Yes, that is why there is no sound in a vacuum.
300
This term describes the movement of charged particles through a circuit that transfers energy.
Electrical Current
300
Do magnets need a medium to transfer energy?
No, magnetism works in a vacuum.
300
To make an electromagnet stronger without adding more batteries, you can ...
Increase the number of coils
Increase the diameter of the coil
300
Which factors affect kinetic energy and lead to higher peak forces?

Which factor of sound affects the highness or lowness of sound you hear?
Pitch (frequency of wave)
400
This term describes the invisible 3-D space around a magnet.
Magnetic Field
400
This is where a magnet "stores" its energy.

400
To change the poles of an electromagnet, you must flip the direction of the ...
Electrical current
You do this by flipping the battery
400
Which force is the main "inhibitor" of kinetic energy?
Friction
400
Which state of matter does sound travel the fastest through?
Solid
