Section 1

(38 cards)

static

Front

the build up of electric charges on an object

Back

coulomb

Front

SI unit of charge. One coulomb (symbol C) is equal to the total charge of 6.24 X 1018 electrons

Back

electrons

Front

these have a negative charge and orbit the nucleus

Back

ion

Front

a particle that is electrically charged

Back

quantized

Front

comes in certain very small amounts

Back

magnitude

Front

how big something is

Back

positive charge

Front

the charge an object ha when it has lost electrons

Back

charged by induction

Front

process of rearranging electrons on a neutral object by bringing a charged object closed to it

Back

neutrons

Front

the particles of the nucleus that have no charge

Back

negative charge

Front

the charge an object has when it has gained electrons

Back

conservation of charge

Front

the principle that net electric charge is neither created nor destroyed but is transferable from one material to another

Back

attract

Front

opposite charges do this

Back

electrical force

Front

a force that one charge exerts on another. When the charges are the same sign, they repel; when the charges are opposite, they attract

Back

law of conservation of charge

Front

charge is neither created or destroyed

Back

field force

Front

force exerted upon another object without physical contact in an electric field

Back

electrostatics

Front

the study of electric charges at rest

Back

coulomb's law

Front

the relationship among electrical force, charges, and distance; the electrical force between two charges varies directly as the product of the charges and inversely as the square of the distance between them

Back

q

Front

symbol used for charge

Back

static electricity

Front

occurs when electric chargers build up when materials are pulled apart or rubbed together

Back

induced

Front

term applied to electric charge that has been redistributed on an object because of the presence of a charged object nearby

Back

electric field

Front

a field of force surrounding a charged particle

Back

repel

Front

two charged that are the same do this

Back

insulator

Front

material that is a poor conductor of electricity

Back

electric field lines

Front

shows direction charged particles will move; direction is for positively charged particles; the closer the lines the stronger the electric field

Back

volt

Front

the standard unit of potential difference and electromotive force

Back

conductor

Front

material, usually a metal, through which electric charge can flow; good conductors of heat are generally good charge conductors

Back

electrostatic equilibrium

Front

that there is no net flow of electric charge or no electric current

Back

coulomb's constant

Front

value of k in Coulomb's Law.

Back

charge by contact

Front

where objects rub against each other to produce electric charge

Back

induction

Front

the charging of an object without direct contact

Back

electric charge

Front

charge obtained by an object when it gains or loses electrons

Back

equilibrium

Front

a stable situation in which forces cancel one another

Back

charge

Front

the fundamental electrical property to which the mutual attractions or repulsions between electrons or protons is attributed

Back

grounding

Front

allowing charges to move freely along a connection between a conductor and the ground

Back

electric field strength

Front

a quantitative expression of the intensity of an electric field at a particular location

Back

electrically polarized

Front

term applied to an atom or molecule in which the charges are aligned so that one side is slightly more positive or negative than the opposite side

Back

charged

Front

referring to matter having an excess of electrons or a deficiency of electrons

Back

protons

Front

positively charged particles located in the nucleus
