6688672036	cation	positively charged ion	3
6688672037	charge	the fundamental electrical property to which the mutual attractions or repulsions between electrons or protons is attributed	4
6688672038	charge by contact	where objects rub against each other to produce electric charge	5
6688672039	charged by induction	process of rearranging electrons on a neutral object by bringing a charged object closed to it	6
6688672040	charged	referring to matter having an excess of electrons or a deficiency of electrons	7
6688672041	conductor	material, usually a metal, through which electric charge can flow; good conductors of heat are generally good charge conductors	8
6688672042	conservation of charge	the principle that net electric charge is neither created nor destroyed but is transferable from one material to another	9
6688672044	coulomb	SI unit of charge. One coulomb (symbol C) is equal to the total charge of 6.24 X 1018 electrons	10
6688672045	coulomb's constant	value of k in Coulomb's Law.	11
6688672046	coulomb's law	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	12
6688672048	electric charge	charge obtained by an object when it gains or loses electrons	13
6688672049	electric field	a field of force surrounding a charged particle	14
6688672050	electric field lines	shows direction charged particles will move; direction is for positively charged particles; the closer the lines the stronger the electric field	15
6688672051	electric field strength	a quantitative expression of the intensity of an electric field at a particular location	16
6688672052	electrical force	a force that one charge exerts on another. When the charges are the same sign, they repel; when the charges are opposite, they attract	17
6688672053	electrically polarized	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	18
6688672054	electrons	these have a negative charge and orbit the nucleus	19
6688672055	electrostatics	the study of electric charges at rest	20
6688672056	electrostatic equilibrium	that there is no net flow of electric charge or no electric current	21
6688672058	equilibrium	a stable situation in which forces cancel one another	22
6688672059	field force	force exerted upon another object without physical contact in an electric field	23
6688672060	grounding	allowing charges to move freely along a connection between a conductor and the ground	24
6688672061	induced	term applied to electric charge that has been redistributed on an object because of the presence of a charged object nearby	25
6688672062	induction	the charging of an object without direct contact	26
6688672063	insulator	material that is a poor conductor of electricity	27
6688672064	ion	a particle that is electrically charged	28
6688672065	law of conservation of charge	charge is neither created or destroyed	29
6688672066	magnitude	how big something is	30
6688672067	negative charge	the charge an object has when it has gained electrons	31
6688672068	neutrons	the particles of the nucleus that have no charge	32
6688672069	positive charge	the charge an object ha when it has lost electrons	33
6688672070	protons	positively charged particles located in the nucleus	34
6688672071	q	symbol used for charge	35
6688672072	quantized	comes in certain very small amounts	36
6688672073	repel	two charged that are the same do this	37
6688672074	Robert Millikan	calculated the charge on an electron and its mass (oil droplet)	38
6688672075	semi-conductor	aterial that can be made to behave as either a conductor or an insulator of electricity	39
6688672076	sink	a process that acts to absorb or remove energy or a substance from a system	40
6688672077	static	the build up of electric charges on an object	41
6688672078	static electricity	occurs when electric chargers build up when materials are pulled apart or rubbed together	42
6688672079	super conductor	a substance that undergoes a change at low temperatures that allows it to conduct electricity with zero resistance	43
6688672080	super-position	the voltage or the current across a conductor in a circuit is the same as obtained by superimposing the voltage and currents due to each of the emfs individually	44
6688672081	torsion balance	measuring instrument designed to measure small forces by the torsion they exert on a thin wire	45
6688672082	volt	the standard unit of potential difference and electromotive force	46
