AP Physics C/Electric Charge

=Fundamentals of Electric Charge= Positive - Lack of electrons Negative - More electrons No charge = Neutral
 * Intrinsic to fundamental particles
 * 2 types: positive (+), negative (-)

Same charges repel: + and + or - and - Opposite charges attract: + and -


 * Coulomb: Measurement of the amount of electric charge (similar to moles in chemistry)

=Atomic Notation=

^A_ZE


 * A = Atomic mass = # protons + # neutrons
 * Z = Atomic Number = # protons
 * E = element symbol (like U for Uranium)
