Make your own MOTOR!

All you need is a battery, a nail, a small magnet, and a wire (foil works better)

Grade Policy

Exams 50% Lab 5%

Quizzes 5% Final 40%

Page 13: Dr. Tatiana Erukhimova [year] Atmospheric Thermodynamics Elementary Physics and Chemistry Gerald R. North Tatiana L. Erukhimova Texas A & M University

You must pass both the lecture (3 midterm exams, final exam, homework) and laboratory parts of the coursein order to pass the course

Grade Policy (cont)

Page 14: Dr. Tatiana Erukhimova [year] Atmospheric Thermodynamics Elementary Physics and Chemistry Gerald R. North Tatiana L. Erukhimova Texas A & M University

•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.

Grade Policy (cont)

Page 15: Dr. Tatiana Erukhimova [year] Atmospheric Thermodynamics Elementary Physics and Chemistry Gerald R. North Tatiana L. Erukhimova Texas A & M University

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

Page 16: Dr. Tatiana Erukhimova [year] Atmospheric Thermodynamics Elementary Physics and Chemistry Gerald R. North Tatiana L. Erukhimova Texas A & M University

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

My Advice to You• Be proactive!! Get into it and have fun• Always watch the chapter outline video and read

the book before you come to class• Be serious about an 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!

I make help sessions before each midterm exam and the final. Week in review on Mondays

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

Consider now a different type of a force…..

Page 29: Dr. Tatiana Erukhimova [year] Atmospheric Thermodynamics Elementary Physics and Chemistry Gerald R. North Tatiana L. Erukhimova Texas A & M University

Consider a force like gravitation which varies as

but 1) billion-billion-billion-billion times stronger;

2) there are two kinds of “matter”: positive and negative; Like kinds repel and unlike kinds attract (unlike gravity where there is only attraction)

From long view of the history of mankind – seen from, say, ten thousand years from now – there can be little doubt that the most significant event of the 19th century will be judged as Maxwell’s discovery of the laws of electrodynamics. The American Civil War will pale into provincial insignificance in comparison with this important scientific event of the samedecade.
