Physics Quiz Flashcards
Like charges ____.
Repel
Opposite charges ______.
Attract
An object that an excess of electrons:
Negative
An object that has a loss of electrons:
Positive
What are the three ways of transferring electric charges?
- Charging by friction
- Charging by induction
- Charging by contact
Charging by friction - matter that had a greater affinity will gain electrons and become:
Negative
Charging by friction - matter that has a lesser affinity will lose electrons and become:
Positive
Charging by contact - happens when a charged object touches a neutral object. Electrons will:
Move out in an attempt to balance the charges.
When the electrons spread out they will move to:
The object with the least number of electrons.
Charging by induction:
A charged object can transfer a charge to a neutral object without touching it.
Object that has the same number of protons and electrons:
Neutral
Insulators:
A substance in which electrons can’t move freely from atom to atom
Conductors:
A substance in which electrons CAN freely move.
