Final Three

Energy of position KE=1/2(m)(V)^2

Unit of work

Unit of power

Watts

Energy can’t be created or destroyed

Joules Same as energy

Energy of position PE=mgh

Flow of charge through a material Unit:Amps (A)

Resistance to the flow of an electric charge Unit: Ohms (weird symbol thing)

An electrical circuit with several different paths for the current to take (Voltages are the same)

Directly touching

A safety device that shuts of when current gets to high Normal household ones usually shut it off at 15-20 Amps

The difference in electrical potential between two places Similar to pressure in a water system

A complete path through which electrical charges can flow

An electrical circuit with only one path for current to flow Current stays same

One object rubbing against another object creating a static charge

Safety device that used thin metal strip that melts if to much current flows through it

A build up of electrical charge on an object…. Usually on the surface of non conductors

Non metal materials that aren’t good at conducting electricity

Unit of resistance (weird symbol thingy)

Ohms (weird symbol thingy)

A device that turns on and off an electrical circuit

Device that uses a metal sphere connected to two thin foil strips to detect electrical charge

Metal objects that are good at conducting electricity
