CULMINATING Physics Flashcards
(19 cards)
What is Static Electricity?
Charge is stationary (an electric charge that is at rest, meaning it has no velocity or movement), builds up on surfaces.
I
What is Current?
The flow of electric charge (electrons). It’s measured in amperes (A) using an
ammeter
(I)
What is Induction?
The transfer of charges by no contact. The object remains overall neutral unless grounded.
What is Charging by Contact?
Both objects end up with the same type of charge.
What is Friction?
When two objects are rubbed against eachother
What is the Electrostatic Series?
A list of materials ranked by their ability to gain or lose electrons through friction.
V
What is Potential Difference?
Potential difference is the energy per charge (V).
(V)
R
What is Resistance?
Resistance is the opposition (goes against) to current flow, measured in ohms (Ω).
What are the 3 types of Charges that can we created on an Object?
Positive, Negative, Neutral
What Type of Charge moves through an Object?
Electrons (negative charges) move through objects.
What Type of Charge moves through a Circuit?
Electrons (negative charges) move through circuits.
What are the 4 points of the Law of Electrostatic
- Like charges repel.
- Opposite charges attract.
- Neutral objects are attracted to charged objects.
- Only electrons move.
How does Matter become Negatively Charged?
By gaining electrons (negative)
How does Matter become Positively Charged?
By losing electrons (positive).
What is Charging by Friction?
When two neutral objects are rubbed together, electrons are transferred from one to the
other, resulting in one becoming positively charged and the other negatively charged.
Describe charging by contact.
A charged object touches a neutral object and transfers electrons. Both objects end up with the same type of charge.
Describe charging by induction. What does induction mean?
Charging by induction occurs without contact. A charged object brought near a neutral one causes a separation of charges. The object remains overall neutral unless grounded.
Compare Static and Current Electricity.
Static electricity: Charge is stationary (an electric charge that is at rest, meaning it has no velocity or movement), builds up on surfaces.
Current electricity: Electrons flow continuously through a circuit.
