9188743463	anion	a negatively charged ion	0
9188743464	attract	opposite charges do this	1
9188743465	cation	positively charged ion	2
9188743466	charge	the fundamental electrical property to which the mutual attractions or repulsions between electrons or protons is attributed	3
9188743467	charge by contact	where objects rub against each other to produce electric charge	4
9188743468	charged by induction	process of rearranging electrons on a neutral object by bringing a charged object closed to it	5
9188743469	charged	referring to matter having an excess of electrons or a deficiency of electrons	6
9188743470	conductor	material, usually a metal, through which electric charge can flow; good conductors of heat are generally good charge conductors	7
9188743471	conservation of charge	the principle that net electric charge is neither created nor destroyed but is transferable from one material to another	8
9188743472	coulomb	SI unit of charge. One coulomb (symbol C) is equal to the total charge of 6.24 X 1018 electrons	9
9188743473	coulomb's constant	value of k in Coulomb's Law.	10
9188743474	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	11
9188743475	electric charge	charge obtained by an object when it gains or loses electrons	12
9188743476	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	13
9188743477	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	14
9188743478	electrons	these have a negative charge and orbit the nucleus, an electron's charge (e) is the smallest amount of transferable charge	15
9188743479	electrostatics	the study of electric charges at rest	16
9188743480	electrostatic equilibrium	that there is no net flow of electric charge or no electric current	17
9188743481	equilibrium	a stable situation in which forces cancel one another	18
9188743482	grounding	allowing charges to move freely along a connection between a conductor and the ground	19
9188743483	induced	term applied to electric charge that has been redistributed on an object because of the presence of a charged object nearby	20
9188743484	induction	the charging of an object without direct contact	21
9188743485	insulator	material that is a poor conductor of electricity	22
9188743486	ion	a particle that is electrically charged	23
9188743487	law of conservation of charge	charge is neither created or destroyed	24
9188743488	magnitude	how big something is	25
9188743489	negative charge	the charge an object has when it has gained electrons	26
9188743490	neutrons	the particles of the nucleus that have no charge	27
9188743491	positive charge	the charge an object ha when it has lost electrons	28
9188743492	protons	positively charged particles located in the nucleus	29
9188743493	q	symbol used for charge	30
9188743494	quantized	comes in certain very small amounts	31
9188743495	repel	two charged that are the same do this	32
9188743496	static	the build up of electric charges on an object	33
9188743497	static electricity	occurs when electric chargers build up when materials are pulled apart or rubbed together	34
