Electric potential energy
|
Electric energy stored in a battery
|
Electrochemical cells
|
Used to convert chemical energy in to electrical enery stored in charges (commonly called cells or batteries)
|
Electrodes
|
The two terminals on a battery
|
Electrolyte
|
Substance that conducts electricity, electrodes are in electrolyte
|
Energy
|
Ability to do work
|
Potential difference/voltage
|
Amount of electric potential energy per one coulomb of charge
|
Volt
|
Unit for measuring potential difference
|
Battery
|
Combination of electrochemical cells connected together
|
Terminals
|
End points on the battery where we make a connection
|
Kinetic energy
|
Energy a moving object has because of its motion
|
Potential energy
|
Energy stored in an object
|
Voltmeter
|
Device that measures the amount of potential difference between two locations of charge separation
|
Friction
|
-rubbing to materials together- can separate charge-separated charges not have electrical energy
|
Piezoelectric crystals
|
Crystals are squeezed, + and - charges are separated on either side f the crystal, a small hammer hits the crystal, generating a bust of thousands of volts of electricity
|
Photo-electrochemical cells
|
Solar panels + calculators- made of semi-conducting material such as silicon- light hits the cell,some of the light energy breaks electrons off the surface of the cell-separated electrons now have the electrical energy needed to operate
