Electriccharge is the physical property of matter that causes it to experience a force when placed near another chargedobject. There are two types of electric charges; positive and negative.
Conductor
An object or typeofmaterial that allows the flow of an electricalcurrent in one or more directions.
Earthing (grounding)
he process of removing the excess charge on an object by means of the transfer of electrons between it and the Earth.
Electrons
A fundamental particle with negative electric charge.
Electrostatic force
Attraction or repulsion of particles or objects because of their electric charge
Friction
The force that opposes the motion of an object. Can cause transfer of electrons.
Insulator
A material whose internal electric charges do not flowfreely
