Introduction to Course Discussion of the Course Background Questionnaire Course Outline Instructor information Required texts Course coverage Grade determination Laboratory schedule Homework problems

Spiral Physics Approach Spiral Learning Different than last semester Grouped by “topic” Group Cooperative Learning - Lecture and Lab Laboratory Activities – some MBL, some simulation, quite a bit of programming, some others CREATION OF FIRST LAB GROUPS – Your Choice Other Tools Ranking Tasks/TIPERs VPython PhET simulations, Physlets Physics, EJS, and other simulations Spreadsheets and others Overview

Course Topics Electricity Phenomena ~ 3.5 - 4.0 weeks Charge and Charge Distribution Electric Field – interaction of a charge/charge distribution with its “environment” Electric Force – interaction between (among) charges/charged objects Electric Potential – interaction of a charge/charge distribution with its “environment”, an alternate approach First a qualitative approach, then a quantitative approach Lab Activities TEST #1

Course Topics II DC Circuits ~ 1.5 - 2.0weeks Basic Circuits – the process of “powering” electronic and electrical devices Simple Circuits – series, parallel, and combination circuits Non-Simple Circuits – looking at more “sophisticated” circuits RC Circuits – using capacitors to store energy or power a circuit Lots of lab activities TEST #2

Course Topics III Magnetic Phenomena ~ 2.0 weeks Magnetic Field – interaction of moving charged particles/current-carrying wires with their “environment” Magnetic Force – interaction between (among) moving particles, current-carrying wires Electromagnetic Induction – the interaction between electric and magnetic phenomena First a qualitative approach, then a quantitative approach Lab activities TEST #3

Course Topics IV AC Circuits and Waves ~ 1.0 – 2.5 weeks AC Circuits – a process of generating alternating outputs for a variety of uses Electromagnetic Waves – interacting electric and magnetic fields propagating through space or a medium Light (Optics) – an example of EM Waves Lab Activities TEST #4 (Optional)

On Overview – Maxwell’s Equations Gauss’ Law of Electric Fields Gauss’ Law of Magnetic Fields Faraday’s Law of Induction Ampere’s/Maxwell’s Law

On Overview – Maxwell’s Equations Gauss’ Law of Electric Fields Gauss’ Law of Magnetic Fields Faraday’s Law of Induction Ampere’s/Maxwell’s Law

Lorentz Force Force of interaction between charges and moving charges (or currents) and a magnetic field

Electricity and Magnetism Conceptual Survey Conceptual survey of your ideas on electrostatic and magnetism Does involve “formal” language (i.e. physics language) NOT FOR A GRADE It is a survey of your current understanding of electrostatic and magnetism ideas

Electric Charges and Their Properties Read pages 3-15. How many different types of electric charges occur in nature? Where does charge come from in nature? What is the fundamental “carriers of charge” in nature? What is the charge of these fundamental carriers? Example P-1 Charged is quantized! Net charge of a closed system does not change! How can “objects/things” not be electrically charged?

Charge Production Experiment Charging by Rubbing an Object Figure P-2 Charging by Induction Figure P-3 Charging by Contact Figure P-4

Electric Charges and Their Properties II What is the polarization of atoms? Figures 5 What is an induced dipole? Conductors and Insulators Figure P-6 Polarization of Insulators Figure P-7 & P-9 Polarization of Conductors Figures P-10 & P-11 (What’s Wrong) Charging, Polarizing and Discharging

Perfect Conductors and Perfect Insulators Electric charges are free to move without any restrictions to their motion. Example - metals Perfect Insulators Electric charges can not move, regardless of the amount of force applied to them. There are no static electric fields present inside perfect insulators. Example – plastic, rubber Reality
