  1. Electricity and Magnetism Physics 208 Dr. Tatiana Erukhimova

  2. Dr. Tatiana Erukhimova [year]

  3. Atmospheric Thermodynamics Elementary Physics and Chemistry Gerald R. North Tatiana L. Erukhimova Texas A & M University SLATE award: 2008, 2009, 2011 Recipient of 2012 Distinguished Achievement University-Level Award in Teaching 2009 AFS College-Level in Teaching

  4. Can you make a light bulb work with a battery and a wire? “Minds of Our Own” by Dr. Matthew H. Schneps and Dr. Philip M. Sadler Harvard-Smithsonian

  5. Make your own MOTOR! All you need is a battery, a nail, a small magnet, and a wire (foil works better) http://en.wikipedia.org/wiki/Homopolar_motor

  6. Overview of Today’s Class • Syllabus and Course requirements • Tricks to survive • Mechanics Review and Coulomb’s Law

  7. Syllabus Instructor Dr. Tatiana Erukhimova Homepagehttp://faculty.physics.tamu.edu/etanya/P208/ Office: Mitchell Physics bldg (MPHY), Room 308

  8. Phone: 845-5644 E-mail: etanya@tamu.edu Class times: MWF: 9:10 am to 10:00 am Sections 521-526 Location: MPHY 205 Office hours: Monday and Wednesday 2pm – 3pm or by appointment

  9. Textbook: “Don’t Panic: Volume II”, by William H. Bassichis, 5th Edition Dedicated students like it! No lab manual is required

  10. Clickers We will use i>clickers for various kinds of assessment: pop quizzes, homework quizzes, in class discussion, etc. You will need to buy i>clicker2 at the MSC Bookstore and register it for this class at www.iclicker.com

  11. Grade Policy Exams 50% Lab 5% Quizzes 5% Final 40%

  12. Grade Policy (cont) You must pass both the lecture (3 midterm exams, final exam, homework) and laboratory parts of the course in order to pass the course

  13. Grade Policy (cont) • If your grade on the Final Exam is higher than your lowest grade on one of the three exams during the semester, the grade on the Final will replace that one lowest exam grade in computing the course grade (it will only replace one grade in case of two exams having the same lowest grade). • The Final Exam grade cannot be used to replace an exam that has been missed without an University excused absence. The missed exam will count as a zero when computing your final grade.

  14. All Exams are • Closed book • No numbers! In general the problems will be formula solutions with variables • Problems will be similar to those on homework and recitation

  15. Homework You’ll have weekly homework assignments Every week you’ll have hw quiz with one problem from your assignment. All quizzes will be given with i>clickers

  16. Check my webpage for hw assignments Example for Week 1 (Week Jan 14): Week Jan 14 (due Jan 21): All Chapter 1 problems and exercises “Due” means that I’ll give you a hw quiz on that day

  17. Exam schedule All mid-term exams will be from 7:00 to 9:30 pm February 12             Exam I March 19             Exam II April 16               Exam III Final             May 6

  18. My Advice to You • Be proactive!! Get into it and have fun • Always read the book before you come to class • Be serious aboutan old rule of thumb:you have to study 2-3 hours a week outside the class per each credit hour • Don’t miss classes (lectures, recitations, labs) • Solve all problems and exercises after each Chapter in the book • Don’t fall into the “I understand the concepts but I can’t do the problems” trap. It means you haven’t done enough of the problems in the chapters. • Every year we have lots of students who really think they understand but fail during the exams. Don’t let this happen to you!

  19. I make help sessions before each midterm exam and the final. (and Monday?) However, these sessions cannot substitute for regular class attendance.  They are to give you a good guidance on how to prepare for the test and to succeed in problem solving. Please check my webpage for help sessions schedule

  20. A little bit of Mechanics A couple of very important concepts: Work Energy Theorem ____

  21. does NOT depend on path!

  22. Mechanical energy is conserved!

  23. Sir Isaac Newton: The Universal Law of Gravitation

  24. m m = - 1 2 U ( r ) G r We can find Gravitational Potential Energy

  25. Consider now a different type of a force…..

  26. Have a great day! Hw: All Chapter 1 problems and exercises Reading: Chapter 1
