Question 7
7.
Why do opposite charges attract?
to keep the charges separate
to try to neutralize the total charge
to transfer positive charges

Question 11
11.
If these negatively charged objects could move on their own, what would they do?
They would get closer together to concentrate and strengthen the charge.
They would move far apart to neutralize the charge.
They would move closer together to neutralize the charge.
Question 3
3.
The word electricity is derived from what?
The Greek word for amber
The name of the Greek god of thunder
The discovery of charged pieces of atoms
The shock you feel from amazement
Question 4
4.
Electrostatic forces from charges are always attractive forces just as gravity is always an attractive force.
True
False
Question 5
5.
What happens to the strength of the force between charged objects as they get closer to each other?
Force strength is not affected by distance.
Force strength decreases as they get closer together.
Force strength increases as they get closer together.
Question 6
6.
Why are the types of charges called positive and negative?
to help us remember how the charges interact
there are two different types of charges, so they needed 2 names
they can cancel each other out like positive and negative numbers in math
they act in opposite ways
They would move far apart to dissipate and disperse the charge.
