1What is a charge produced by rubbing or touching objects together?Electrostatic electricity
2Unbalanced chargesA more correct term for static electricity, because the charges are not stationary; rather they move
3Positive chargeWhen an object has a deficit of electrons
4Negative chargeWhen an object has extra electrons
5Laws of ChargesLaws that describe the behavior between charged and uncharged objects
6What are the 3 laws of charges?1. Unlike charges attract
2. Like charges repel
3. Charged objects attract uncharged (neutral) objects
7InsulatorAn material in which the charge stays on the spot where the object rubbed; most non-metals are insulators
8ConductorMaterials that allow charges to move freely; most metals are conductors
9Super-conductorMaterials that offer little or no resistance to the flow of electrons
10DischargeFeeling or seeing small sparks
11NeutralizedThe removal of charge (through electrical discharge) so that the overall charge is neutral
12GroundingConnecting an object to Earth with conducting wire to safely rebalance a charge
