A form of energy that is a result of charged particles, namely electrons and protons.
An electric charge that stays on an object instead of flowing, thus the name static.
Charging by friction
A form of creating net static charge by rubbing two materials together.
i.e. Rubbing your hair on a balloon is a from of charging by friction.
A list of materials based on their ability to hold on to electrons.
A material that does not allow electrons to move easily between atoms.
i.e. Vinyl has a strong hold on electrons, and therefore is an insulator.
A material that allows electrons to move easily through atoms.
i.e. The human body allows easy electron flow, so it is a conductor.
A material where electrons can move somewhat easily between atoms.
i.e. Silk and cotton have a fairly strong hold on electrons and are considered semiconductors.
An object that can add or take away a large number of electrons to neutralize it.
i.e. The Earth's surface is an example of a ground. It's ability to supply or take away electrons is so great that it always remains neutral.
A device used to detect an electrical charge.
Charging by contact
Generating a charge on a neutral object by touching it.
Laws of electric charges
States how two objects interact electrically when they are charged or neutral.
- i.e. Like charges repel
- Opposite charges attract
- Any charge attracts a neutral object
An area of space around a charged object where its charge's effect is felt by other objects.
Induced charge separation
The movement of electrons in a substance without contact between objects due to electrical fields.
a charged atom or group of atoms.
A metal sphere or point attached to a building's highest point and is connected to the ground.
A cleaner that removes unwanted particles and liquid from a gas flow.
Van de Graaff generator
A device that accumulates and transfers very large charges.
A device that detects and measures exposure to radiation.
