Notes on Chapter 32 Electrostatics
Electrostatics Electrostatics – electricity that does not move or is static All electricity comes from electrical forces from atoms -Atoms contain protons.
Electrical Charge is all about ELECTRONS! A gain of electrons causes a negative charge. A loss of electrons causes a positive charge.

STATIC ELECTRICITY Electric charge 12 p+ Atoms are neutral Same # of protons as electrons.
Electricity! Law of Electric Charges Like charges repel; Opposite charges attract.
 Two types of electric charges  Proton: positive charge  Electron: negative charge  Positive charge of proton = negative charge of electron.

(c) McGraw Hill Ryerson 2007 Force = a push or pull electric force does this without touching the object so is an action-at-a-distance force Laws of Static Charge Like charges repel Opposite charges attract Neutral objects are attracted to charged objects See pages 258 - 259 (c) McGraw Hill Ryerson 2007

(c) McGraw Hill Ryerson 2007 Charging Objects 1. By Conduction through direct contact Extra electrons will move to a location where there is less of them See pages 259 - 260 (c) McGraw Hill Ryerson 2007

2. By Induction Bringing a charged object nearby a neutral object will cause electrons to move Take the Section 7.2 Quiz
