16320388446Neutral ChargeAmount of protons = amount of electrons1
16320388447Law of Electric Charges1. Like charges repel (move away). 2. Unlike charges attract (move together). 3. Charged objects attract neutral objects.2
16320388448static electricityThe buildup of charges on an object3
16320388449lightningA sudden spark, or energy discharge, caused when electrical charges jump between parts of a cloud, between nearby clouds, or between a cloud and the ground.4
16320388450insulatorA material that does not allow heat or electrons to move through it easily.5
16320388451conductorA material that allows heat and electricity to pass through it.6

16320388456Frictiona method of charging an object by rubbing it against another object11
16320388457Conductiona method of charging an object by allowing electrons to flow by direct contact from one object to another object12
16320388458Inductiona method of charging an object by means of the electric field of another object13
