SNC1DW Chapter 10
Glossary terms and definitions for Chapter 10.
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
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.
