AP Physics 2 : Electrostatics Flashcards

7673253159	attract	opposite charges do this	0
7673253162	charge	the fundamental electrical property to which the mutual attractions or repulsions between electrons or protons is attributed	1
7673253163	charge by contact	where objects rub against each other to produce electric charge	2
7673253164	charged by induction	process of rearranging electrons on a neutral object by bringing a charged object closed to it	3
7673253165	charged	referring to matter having an excess of electrons or a deficiency of electrons	4
7673253166	conductor	material, usually a metal, through which electric charge can flow; good conductors of heat are generally good charge conductors	5
7673253167	conservation of charge	the principle that net electric charge is neither created nor destroyed but is transferable from one material to another	6
7673253168	coulomb	SI unit of charge. One coulomb (symbol C) is equal to the total charge of 6.24 X 1018 electrons	7
7673253169	coulomb's constant	value of k in Coulomb's Law.	8
7673253170	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	9
7673253171	electric charge	charge obtained by an object when it gains or loses electrons	10
7673253172	electric field	a field of force surrounding a charged particle	11
7673253173	electric field lines	shows direction charged particles will move; direction is for positively charged particles; the closer the lines the stronger the electric field	12
7673253174	electric field strength	a quantitative expression of the intensity of an electric field at a particular location	13
7673253175	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	14
7673253176	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	15
7673253177	electrons	these have a negative charge and orbit the nucleus	16
7673253178	electrostatics	the study of electric charges at rest	17
7673253179	electrostatic equilibrium	that there is no net flow of electric charge or no electric current	18
7673253180	equilibrium	a stable situation in which forces cancel one another	19
7673253181	field force	force exerted upon another object without physical contact in an electric field	20
7673253182	grounding	allowing charges to move freely along a connection between a conductor and the ground	21
7673253183	induced	term applied to electric charge that has been redistributed on an object because of the presence of a charged object nearby	22
7673253184	induction	the charging of an object without direct contact	23
7673253185	insulator	material that is a poor conductor of electricity	24
7673253186	ion	a particle that is electrically charged	25
7673253187	law of conservation of charge	charge is neither created or destroyed	26
7673253188	magnitude	how big something is	27
7673253189	negative charge	the charge an object has when it has gained electrons	28
7673253190	neutrons	the particles of the nucleus that have no charge	29
7673253191	positive charge	the charge an object ha when it has lost electrons	30
7673253192	protons	positively charged particles located in the nucleus	31
7673253193	q	symbol used for charge	32
7673253194	quantized	comes in certain very small amounts	33
7673253195	repel	two charged that are the same do this	34
7673253199	static	the build up of electric charges on an object	35
7673253200	static electricity	occurs when electric chargers build up when materials are pulled apart or rubbed together	36
7673253204	volt	the standard unit of potential difference and electromotive force	37
