Electric Potential Energy and Voltage

Voltmeter

- device that measures the amount of potential difference between two locations of charge separation.

Wet cell

- electrolytes that take form in fluid.

Thermocouples

- consists of a loop of two wires of different metals joined at both ends, if one end is heated or cooled, charge is separated, and potential difference /voltage is created.

Electrode

- two terminals of a battery.

Terminal

- end points of a battery where connection is made.

Friction

- rubbing two materials together, work done by rubbing is converted into electrical energy stored into the separate charge.

Chemical energy

separates the positive and negative charges in a battery.

Piezoelectric crystals

- when collided against, positive and negative charges are separated on either side of crystal.

Acceleration

- increased rate or speed of something.

Potential Energy

- energy stored within an object (measured in joules)

Potential Difference

- amount of electric potential energy per one coulomb of charge.

Electrochemical Cell

- cell that converts chemical energy into electrical energy stored in charges (typically called cells or batteries)

Electric Potential Energy

- electrical energy stored within a battery.

Energy that charge possesses

is dependent on amount of charge and potential difference /voltage.
