Electricity
what is electric charge?
Everything or anything related to electricity.
What does it mean when an object has a net charge?
That it has more positive or negative charges than the other.
What's the name of the magnet poles?
north and south
the north pole of 2 magnets will
attract or repel
The north and south pole of 2 magnets will
attract or repel
attract
What does it mean when an object has zero net charge?
that it has the same amount of negative and positive charges.
What does it mean when an object has positive net charge?
It has more positive charges than negative charges.
What's the name of the mineral all magnets have?
magnetite
give me 2 examples of nonmagnetic materials?
gold, copper, wood, water.
Give me 2 examples of magnetic materials
steel and iron
2 objects with positive net charge.
repulsion
Is there repulsion or attraction?
2 objects, 1 with positive net charge and 1 with negative net charge?
attraction
What are magnetic forces?
force that attracts or repels magnets even when they are not in contact.
What does it mean when a material is considered magnetic?
materials that can be attracted to magnets.
Why is the battery an example of electric discharge at a distance?
the positive and negative charges are not in contact, the electric discharge happens through a wire.
When an object goes through an electric charge, this means that:
it gains electric charges and creates a net charge, either negative or positive.
When an object undergoes an electric discharge it means that:
the object lost electric charges.
SURPRISE QUESTION
What are parallel circuits ?
each load connects directly to the power source so if one wire/path stops working, it doesn't affect the other load.
SURPRISE QUESTION!
What is a series circuit?
All the loads are connected through one path so if 1 load stops working it can affect the rest.
What is an electric current?
constant flow of electric charges
Why is lightning a good example of electric discharge at a distance? why can it happen?
there is a huge difference between the net charges of both objects so they don't need to be in contact.
Why do objects go through an electric discharge?
to find an equilibrium between the 2 objects so both of them can get zero net charge.
How does a compass work with the terrestrial poles?
The south needle of the compass is attracted to the north pole and the north needle of the compass is attracted to the south pole.
What does it mean when an object becomes magnetized?
when the object is influenced by the magnet, it gets magnetized which means that it becomes a magnet too.
What are the 5 parts of the an electric circuit?
wire, load, switch and energy source.
