Electricity Chapter10 Glossary Terms - SNC1DW (Sem1)

A form of energy that results from the interactions of charged particles, such as electrons and protons

An electric charge that tends to stay on the surface of the object, rather than flowing away quickly

When objects made from different materials rub

• A list of materials that have been arranged according to their ability to hold on to electrons
• Closer to top has a weaker hold

• A material in which electrons cannot move easily from one atom to another
• I.e. wood, rubber, plastic (Non-metal)

• A material in which electrons can move easily between atoms
• I.e. Copper, aluminum (Main metal)

• Non-metals in which electrons move fairly well
• I.e. Silicon

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 the object

• A device for detecting the presence of an electric charge
• Metal leaf
• Pith ball
• 

Generating a net charge on a neutral object by touching it with a charged object

Laws that describe how two objects interact electrically when one or both are charged

• A property of the space are a charged object, where the effect of its charge can be felt by other objects
• Objects with greater net charges have stronger electric fields

The movement of electrons in a substance, caused by the electric field of a nearby charged object, without direct contact

A charged group of atoms

• A metal sphere or point, attached to the highest part of a building and connected to the ground
• On top of CN Tower

• A type of cleaner that removes unwanted particles and liquid droplets from a flow of gas
• 1907 patented

A device that accumulates a very large

charge 

A small device that detects and measures exposure to radiation
