A form of energy that results from the interaction of charged particles
Static charge (static electricity)
An electric charge that tends to stay on the surface of an object, rather than flowing away quickly
Charging by friction
A process in which objects made from different materials rub against each other, producing a net static charge on each object
A list that ranks the objects ability to take negative charges.
A material in which electrons can't move easily from one atom to the other
e.g. plastic, wood, rubber
A material in which electrons can move easily between atoms
e.g. copper, aluminum, water
A material in which electrons can move fairly well between atoms
An object that can supply a very large number of electrons to, or can remove a very large number of electrons from, a charged object, thus neutralizing that object
an instrument for detecting and measuring electricity
Charging by contact
When a charged object touches another object.
Laws of electric charges
opposites attract, like charges repel, neutral attracts
a region around a charged particle or object within which a force would be exerted on other charged particles or objects.
Induced charge separation
the movement of electrons in a substance, caused by the electric field of a nearby charged object without direct contact between the substance and the object.
an atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
a metal rod or wire fixed to an exposed part of a building or other tall structure to divert lightning harmlessly into the ground.
a device that removes suspended dust particles from a gas or exhaust by applying a high-voltage electrostatic charge and collecting the particles on charged plates.
Van de Graaff generator
a machine devised to produce a high voltage by means of an endless belt collecting electrostatic charge from a source and transferring it to a large isolated metal dome, on which a large charge accumulates.
Dosimeters measure an individual's or an object's exposure to radiated energy
