Materials can become electrically charged
Charging without touching is called induction.
When charged comes near uncharged, opposites will go towards charged and negative will stay away.
the position of the charges return when the charged object is pulled away.
the charged particles in the atoms can be polarized to go towards the charged object.
When two uncharged objects made of certain materials touch, they can become charged.
Materials affect the charging process. Certain materials will ALWAYS give electrons to another when touching.
skin to glass to hair to nylon to wool to fur to silk to paper ti rubber to polyester.
Static charges are from movements of electrons.
If there are more protons than electrons, then the object is positively charged.
If there are more electrons than protons, then the object is negatively charged.
remember: protons CANNOT move.
Charge is measured in coulombs, which are 10^19 electrons or protons.
Protons and electrons have electric change
Electric charge is the property of a material that allows it to use electrical force on without touching another object
The space where a such a charged material can use electrical force is called an electric field.
Protons have positive electric charge while electrons have negative electric charge.
Objects with the same charge repel, and objects with different charges attract.
Technology also uses static electricity, such as photocopiers, panting a car, and electrostatic air filters.
Charges can move from one place to the next.
