Methods of charging

Friction- rubbing two objects together.

Conduction-direct contact of objects, electrons flow through one object to another.

Induction- involves a rearrangement of electric charges

Static Electricity

An atom has an equal number of protons and electrons. So the total positive charge is equal to the negative charge, the charges cancel out.

Even though an atom contains charged particles, it is electrically neutral.

A neutral object acquires an electric charge when it gains or loses electrons.

Law of Conservation Charge- charge is only being transferred from one object to another

Conductor- materials that permit electric charge to flow freely

Insulator- materials that don't allow electric charges to flow freely

Static Electricity:The transfer of electrons from one object to another without further movement.

Electric discharge- the loss of static electricity as electric charges move off an object.

Electrons moving from one object to another causes buildup of charges at rest.
