Can the balloon be attracted to the wall?
No. The balloon is negative so it can be only attracted to a positive.
Yes. The balloon is negative, but it will push the protons on the wall away and attract to the electrons on the wall.
Yes. The balloon is negative, but it will push the electrons on the wall away and attract to the protons on the wall.
No. The balloon is negative so it can be only attracted to a negative.
Which statement is an INFERENCE about the results of the two situations.
The balloon in A moves towards the sweater faster than B.
The GREATER the DIFFERENCE in charge, the STRONGER the electric force.
That balloon in B moves towards the sweater faster than A.
The GREATER the DIFFERENCE in charge, the WEAKER the electric force.
Which of the following could be true of an electrically negative object? Choose all that apply
It contains only negative charge
It contains more negative charge the positive charge
It is attracted to an electrically neutral object
It is attracted to an electrically positive object
It is attracted to an electrically negative object
For something to be positive, what must happen.
It must loose protons
It must gain electrons
It must loose electrons
It must gain protons
A group of students decided to test how the amount of charge affects the strength of attraction between the balloon and the sweater.
What was the independent variable?
the difference in charge
the strength of attraction
the strength of attraction
the sweater

True
False
Which of the following would cause the balloons to REPEL one another?
both of these
rubbing one of the balloons on the sweater, then bringing it near the other balloon
neither of these
rubbing both balloons on the sweater, then bringing them near one another

Oppositely charged objects repel one another.
True
False
Which of the following describes the balloon? Choose all that apply!
It is electrically neutral.
It is not electrically charged.
It contains charges.
Styrofoam is an insulator. Which of the following is therefore true of styrofoam?
It can become electrically charged
It allows charge to flow freely through it
It is always electrically negative
In which direction will charge travel once the inside and outside conductors are connected?
Charge will travel through the metal rod from the outside to the inside of the jar.
Charge will travel through the metal rod from the inside to the outside of the jar.
Charge will travel through the glass from the foil inside to the foil outside the jar.
Charge will travel through the glass from the foil outside to the foil inside the jar.
Where is charge stored in the Leyden jar?
In the metal chain
In the lead foil on the inside
In the lead foil on the outside
In the lead foil, both inside and outside
In the glass jar
The charge on the sweater is neutral. What must be true about the atoms that make up the sweater?
There is an equal amount of protons and neutrons.
There are more electrons than protons.
There is an equal amount of protons and electrons.
There are more electrons than protons.
There are more protons than neutrons.
Static discharge occurs when
positive charges accumulate on an insulator.
a charged object comes near a conductor.
a charged object comes near an insulator.
In which situation would the balloon and sweater have the WEAKEST attraction and why?
Situation A because the closer they are, the stronger they attract.
Situation A because the closer they are, the less they attract.
Situation B because the farther away they are the stronger they attract.
Situation B because the farther away they are, the less they attract.
For something to become negative, what must happen?
It must lose protons.
t must lose electrons.
It must gain electrons.
It must gain protons.
What needs to happen for this balloon to become negatively charged?
Nothing. It is already positively charged.
Positive charges must be transferred to the balloon from another material.
Negative charges must be transferred to the balloon from another material.
Positive charges must be transferred from the balloon to another material.
Negative charges must be transferred from the balloon to another material.
Based on the structure of the atom, why would the electrons be the ones to rub off and transfer to another object due to friction?
Electrons are zipping and zooming like crazy.
Electrons have very little mass.
Electrons are on the outermost part of the atom.
A group of students decided to test the effect of distance on the strength of electric force.
What is the independent variable in this experiment?
difference in charge
strength of electric force
distance
A group of students decided to test how the amount of charge affects the strength of attraction between the balloon and the sweater.
What was the dependent variable?
the difference in charge
the strength of attraction
the balloon
the sweater
What needs to happen for this balloon to become positively charged?
Nothing. It is already positively charged
Positive charges must be transferred to the balloon from another material.
Negative charges must be transferred to the balloon from another material.
Positive charges must be transferred from the balloon to another material. Selected:
Negative charges must be transferred from the balloon to another material.
Why are metals good conductors?
They have more electrons than protons.
They don't have a tight hold on their electrons and share them in large groups.
They have more protons than electrons.
They have a very tight hold on their electrons and do not share them.
In order for an object to become electrically charged, which of the following must be true?
The object must have fewer neutrons than protons or electrons.
The object must be a conductor of electricity
Negative charges must be transferred to OR away from the object.
Positive charges must be transferred to OR away from the object.
Which way will the balloon move and why?
The sweater is the only object that can attract the balloon since they have opposite charges.
The balloon will be more attracted to the wall than the sweater because the difference in charge is GREATER between the wall and the balloon.
The balloon will be more attracted to the sweater than the wall because the difference in charge is GREATER between the sweater and the balloon.
