QuestionAnswer
The study of electrec charges at rest. electrostatics
Aforce tatl one charge exertson another. When the charges are the same sign, they repel;when the charges are opposite, they attract. electrical forces
The fundamental clectrical property to which the mutual attractions or repulsions between ewctrons or protons is attributed. charge
The principle that net clectric charge is neither created nor destroyed but is transferablefrom one material to another. conservation of charge
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 spuare of the distance between them. Coulomb's law
SI unit of charge. One coulonb is equal to the total charge of electrons. coulomb
Material, usually of metal, through which electric charge can flow. Good conductors of heat are generally good charge conductors. conductor
A material that is a poor conductor of electricity. insulator
Material that can be made to behave a either a conductor or an insulator of electricity. semiconductor
Term applied to electric charge that has been redestributed on an object because of the presence of a charged object nearby. induced
The charging of an object without direct contact, induction
allowing charges to move freely along a connection between a conductor and the ground. grounding
an atom or molecule in which the charges are aligned so that one side is slightly mor positive or negative than the opposite side. electrically polarized
