SNC1DW 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 static.

• 

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.

Generating a charge on a neutral object by touching it.

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.

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.

A device that accumulates and transfers very large charges.

A device that detects and measures exposure to radiation.
