Q3 Physics Quiz 2 Flashcards
Pairs of electrical charges interact with each other according to the law of _____ _____
Law of Electric Charge
The attractive or repulsive interaction between any two charged objects is an ____ ______
Electric Force (Felectric).
A SHORTER distance between chargers will experience a _______ electric force, the FARTHER the distance gives ______ electric force
greater ; weaker
All charged particles will experience a force around them. And that region around an electrical charge particle where force is detected is called ______ _______.
Electric Field
ELECTRIC _____ _______ go away from POSITIVE charges and toward NEGATIVE charges
FIELD LINES
T or F. No two field lines from the same field can cross each other.
T
T or F. The number of lines drawn leaving a positive charge or approaching a negative charge is NOT PROPORTIONAL to the magnitude of the charge.
F
Pairs of electrical charges have a force that acts between them.
ELECTRIC FORCE
electric force can be either be attractive or ______
REPULSIVE
______ deals with the interaction of electric charge at rest.
ELECTROSTATICS
The process of SUPPLYING the electric charge to an object or LOSING an electric charge from an object is called _______.
CHARGING
Electric charge is _______. It can be TRANSFERRED from one object to another by moving electrons but it can not be created nor destroyed.
CONSERVED
In the experiment, the hair becomes positively charged because it has a DEFICIENCY in electrons after ______.
rubbing
In the experiment, after rubbing, the balloon becomes negatively
charged because it has excess ________.
electrons
When an object has an equal number of protons and electrons it means the object is ________ charged.
neutrally
UNLIKE charges _____ and LIKE charges _____
attract ; repel
law that states that charges repel and unlike charges attract.
law for electrostatic charge
Give the processes of Charging
Charging by Friction
Charging by Conduction
Charging by Induction
When two objects are rubbed against each other, charge transfer
takes place. One of the objects loses electrons while the other object
gains electrons
Charging by Friction
Charging by Friction is also known as _______ by friction
electrification
The method of charging an uncharged object by bringing it close and IN CONTACT with a charged object. The charged conductor has an unequal number of protons and electrons, hence when an uncharged conductor is brought near it, it discharges electrons to stabilize itself
charging by conduction
______ ______ is generated by the flow of negatively charged electrons, positively charged holes, and positive or negative ions in some cases.
Electrical current
A _____ is an object or type of material that allows the flow of charge (electrical current) in one or more directions
conductor
The process of charging an uncharged conductor by bringing it near acharged conductor WITHOUT any PHYSICAL CONTACT.
charging by induction
An electrical ______ is a material in which the electron does not flow freely or the atom of the insulator has tightly bound electrons whose internal electric charges DO NOT flow freely; very little electric current will flow through it under the influence of an electric field.
insulator
All matters are said to be neutral wherein the numbers of electron and protons are equal so once charges it do not stay for a long time because of the following factors EXCEPT:
A. amount of charge gain
B. presence of polar molecules
C. type of charge
D. type of material
C. type of charge
A negatively charged object is brought close to the surface of a conductor, whose opposite side is then grounded. What kind of charge is left on the conductor’s surface?
A. neutral
B. negative
C. positive
D. both positive and negative
C. positive
