Conservation of Charge
Electrons are transferred from one object to another. One gains, one loses, total charge is unchanged. (Rubbing)
Friction
What do opposite charges do?
Attract
Two electric fields have the same charge. What are the lines going to show?
Moving away from each other/ repelling
Electrons move directly through contact. Charge is shared, not created. (Touching)
Conduction
What do same charges do?
Repel
Two electric fields have different charges. What is the line going to show?
Lines connecting/ attracting
Charges rearrange without contact. No electrons are added or removed; total charge stays the same. (Near)
Induction
Which element transfers transfers?
Electrons
Which way do positive electric fields point?
Out
Charges shift slightly inside a neutral object. Total charge doesn’t change. (No Transfer)
Polarization
What charge do electrons hold?
Negative
Which way do negative electric field lines point?
In
A negatively charged balloon is brought near a neutral metal can. What happens to the charges in the can?
Electrons move to the side of the can farthest from the balloon.
