Question | Answer |
electrostatics | the study of electric charges at rest. |
electrical forces | a force that one charge exerts on an other when the charges are the same sign, they repel; when opposite they atttract |
charge | the fundemental electrical preoperty to which the mutual attractions or repulzions between electrons and protons are attributed. |
conservation of charge | hte principle that net electric charge is neither created nor destroyed byt can be transferred |
coulombs law | the relationship with electrical force, charge, distance: the force between two charges varies as the product of the charges and inversly as the squareof the distance between them |
coulombs | si unit of charge |
conductor | materical through which heat can be transferred. |
insulator | a material that is a poor conductor of heat |
semiconductor | materical that behaves like a conductor and insulator. |
induced | term applied to electric charge that has been redistributed on an object because the charge nearby. |
induction | the charge of an object without direct contact |
grounding | allows charges to move freely between a conductor and the ground |
electrically polarized | an atom or molecule in which the charges are alligned so that one side is slightly more positive or negative. |
