Topics in the book by Nicholas Giordano 2nd Edition
Chapter 17Electric Forces and Fields
Note: These Lectures (Power Point) are are UNDERGOING CONSTRUCTION!!
A GOAL is to post a lecture before we discuss a topic in class, but I can't promise!

Chapter Summary: A File Provided by the Publisher!
Part I: Section 17.1: Evidence for Electric Forces: Observational Data.
      Properties of Electric Charges:
       1. There are 2 Kinds of Charge: Positive & Negative
       2. Like Charges Repel & Unlike Charges Attract
       3.  Charge is Conserved.  Can be transferred, but not created or destroyed.
       4. Charge is Quantized. Always comes in integer multiples of electron charge e.
Part II: Section 17.2: Electric Forces & Coulomb's Law
      Electric Forces are Vector Forces!  
       1. Understanding vectors (Physics I) is vital to understand electrostatics!
       2. Electric Force between charges q1 & q2 distance r apart varies as (1/r2).   
       3. Total force on a charge  = VECTOR SUM of  forces due to all other charges.
       4.  In calculations, try to use "common  sense"  to see if answer is correct
Part III: Sections 17.3 & 17.4: The Electric Field.
       Electric Fields are Vectors!
      Electric Fields near Conductors & Insulators
       1. Electric Field is defined as the Coulomb Force divided by a test charge.
       2. Electric Field Lines. 
       3. Total Electric Field at a Point = VECTOR SUM of  Fields due to all charges.
Part IV: Supplement:  Fields of Continuous Charge Distributions. 
       Overview Only!
Part V: Section 17.5: Electric Flux & Gauss's Law.
     1. Electric Flux is Defined as Electric Field Divided by Area
      2. Gauss's Law: Electric Flux Through Closed Area = (Charge Enclosed)/(Epsilon0)
      3. Gauss's Law & Coulomb's Law give the same Physics.
      4.  Gauss's Law is Useful & Practical Only for High Symmetry.
