It's a challenging course. Talk to us if you start to get lost or are confused about a concept. It's your responsibility to come to us for help. It's our responsibility and pleasure to help you!
1. COURSE GOALS AND OBJECTIVES
The introductory physics course sequence for engineers and scientists is intended:
a) to help you to obtain a basic familiarity with the observations and experimental results on natural phenomena which occur on the scale of "ordinary sized" objects traveling at "ordinary speeds" (CLASSICAL PHYSICS);
b) to develop a working knowledge of the small number of fundamental theories which explain the diverse phenomena which occur in nature by applying them to derive the formulas which apply to particular situations using rigorous problem solving methods.
In particular in 95.144 Physics II you will develop an understanding of the phenomena of classical optics, classical electromagnetism as well as the theories used to explain them.
Specific Learning Objectives:
The following are some examples of the specific learning objectives on which you will be tested in the homework assignments, quizzes, three one hour examinations and the final examination (The Learning Objectives are listed at the beginning of each section of the lecture notes.):
To be able to demonstrate your understanding of the experiments and concepts underlying optics and electromagnetic theory by correctly answering multiple choice questions in the examinations on these topics which are presented in the textbook and lectures.
To be able to calculate the interference and diffraction maximum and minimum points on a screen due to the passage of electromagnetic waves through a single slit, pair of slits or a grating,
To be able to calculate the total force on a test charge and the electric field due to a set of charges (point or continuous) using the superposition principle for forces and fields,
To be able to calculate the total electric potential due to a set of charges (point or continuous) using the superposition principle for electric potentials,
To be able to apply Gauss’ law or Ampere’s law to uniform, symmetrical charge or current densities and derive the formula for the resulting electric or magnetic fields,
To be able to calculate the electromagnetic force (Lorentz force) on a test charge (stationary or moving at a constant speed) due to applied electric or magnetic fields,
To be able to calculate the acceleration, velocity and position of a test charge as a function of time due to a constant electromagnetic force,
To be able to apply the Faraday or Ampere-extended laws to time varying magnetic or electric fluxes and derive the formulas for the resulting induced electric or magnetic fields and forces,
To be able to write the four Maxwell equations in integral form and use them to calculate the properties of electromagnetic waves,
To be able to calculate the energy and momentum in an electromagnetic wave.
2. COURSE MATERIALS AND DESCRIPTION
The required course text is: Physics for Scientists and Engineers, 4th ed., vol.II, by Giancoli, published by PEARSON Prentice-Hall, Inc. (2008). In addition, the COURSEPACK containing the lecture notes and a permit for use of the PhGradeAssist2 computer practice homework system and the PRS (RF model not IR model) electronic lecture transponder must be purchased along with a solution manual for the odd numbered problems of the text and a CD-Physics disk. The bundled package is available from the UML North Bookstore.
95.144 Physics II is the second semester of a two semester calculus based sequence for engineering and science majors. The topics which will be covered are: Optics including reflection, refraction, interference, and diffraction; Electricity and Magnetism including Coulomb's Law, electric field, Gauss' Law, electric potential, Ohm's Law, D.C. circuits with resistors, magnetic field, current loops, Ampere's Law, Faraday's Law, inductance, Maxwell's equations, and electromagnetic waves. Prerequisite: 95.141. Co-requisites: 92.132, 96.144.
3. PREREQUISITES AND CO-REQUISITES
All students should have successfully completed the 95.141 PHYSICS I course at UMass Lowell or its equivalent at another institution. All students must either be currently enrolled in 92.132 CALCULUS II or have successfully completed it at UMass Lowell or its equivalent at another institution. In addition, all students must either be currently enrolled in the co-requisite laboratory course 96.144 EXPERIMENTAL PHYSICS II or have successfully completed it at UMass Lowell. All equivalency determinations must be made by the department giving the corresponding course at UMass Lowell if you were not already given transfer credit upon admission to the University. Please contact the transfer credit evaluator in the appropriate department.
Our course meets five times per week, two lecture classes, two recitations and one laboratory. The lecture schedule is listed in item 12. You should have read the lecture material to be covered in the textbook and Coursepack before attending each lecture. You may be asked questions on this material during the lecture which you will answer using the PRS transponder. The lectures are primarily intended to familiarize you with the phenomena being studied and the basic physical concepts used to understand the phenomena. The lectures will be interactive using the electronic transponder (PRS) and highlight the important points in the text, clarify confusing concepts, illustrate some phenomena with demonstrations and in some cases supplement the textbook material with new topics. Therefore, you should attend all lectures, and take supplementary class notes particularly when a topic is presented which was not clear from your reading. Class attendance and participation will be counted toward your course grade. (See section 9, How Your Grade Is Determined). Your notes should be kept in an organized manner in a notebook(There are Class Notes pages in the Coursepack.) for reference when studying for examinations.
Recitation classes are smaller than the lecture class and are intended to help you to review the homework assignments with particular emphasis on problem solving techniques, to answer your questions on the lecture material or the assignment, to highlight your strong and weak areas by giving you a quiz and to prepare you for the examinations. The recitation schedule is listed in item 12. You should do the homework assignments regularly prior to class. The assignments will be graded and returned to you as soon as possible after you submit them. You should also write down the problem solutions given by your recitation instructor in your notebook for future reference if you had difficulty with any of the problems in the assignment.
Your recitation instructor may give you extra credit assignments to improve your homework grade if he/she feels that it is appropriate. You will also have practice assignments and tests available on the computer PhGradeAssist2 system which are not graded but will give you immediate feedback on your understanding of the homework assignments and preparation for the tests.
The laboratory class is limited in size so that each student will have an opportunity to get hands-on experience with operating the apparatus, observing the phenomena and making precise measurements from which the results are extracted by data analysis techniques. Furthermore, a written report for each experiment is required in order to help you develop the technical writing skills necessary in all areas of engineering and science. Every effort is made to coordinate the experiment to be performed with the lecture material. However, this may not be possible in all cases. A few topics such as geometrical optics and RC circuits may be covered only in the laboratory. Therefore, you should take careful notes during the pre-laboratory lectures.
5. EXAMINATIONS AND EXAMINATION SCHEDULE
Common examinations (EXAM I, II, III) will be held during the lecture hour on the dates listed below. The room for all three of the examinations will be the lecture room. In addition, there will be a comprehensive three hour FINAL EXAMINATION during finals week at the end of the semester. The time and place for the FINAL EXAMINATION will be announced near the end of the semester. You are required to attend each examination at the officially announced time. See ATTENDANCE/ABSENCE AND DISABILITIES POLICIES in item 8 below.
You must bring pencils, erasers and a calculator to each examination session. A formula sheet will be provided with each examination listing all formulas for the entire course. YOU WILL BE ASKED TO TURN OFF ALL CELL PHONES AND PLACE THEM IN FRONT OF THE ROOM. The examinations will be graded and returned to you in your recitation class within one week. Upon receiving your examination you should check the grading against the solutions which will be reviewed in recitation class by your instructor. The average grades will be posted on the Forum page of the course website. If you have any questions about the score or grading policy, you must write the problem number you want re-graded and the reason on the front cover of the examination only and turn the examination in to your recitation instructor at the next class. As a result of the regrade you may get additional points, no change in your grade or your grade may be decreased. This procedure will not apply to the FINAL EXAMINATION. However, you may request to see your FINAL EXAMINATION within the first two weeks of the next semester by contacting your recitation instructor who is responsible for your course grade and can make changes if necessary.
EXAMINATION SCHEDULE: DURING LECTURE CLASS ON DATES LISTED BELOW. (NO MAKE-UP EXAMS WILL BE GIVEN. SEE ITEM 8.)
10/03 EXAM I CH 15,32,34,35
10/31 EXAM II CH 21,22,23,24
11/21 EXAM III CH 25,26,27,28
12/16 FINAL EXAM Material from Exams I,II,III
6. HOMEWORK POLICY
Homeworks are assigned to you twice each week and are due on the dates indicated in the LECTURE/RECITATION ASSIGNMENT SCHEDULE in item 12 below. All of your homework will be graded and returned to you as soon as possible. The two lowest homework grades will be dropped from consideration. If you do not complete your homework on time, it will result in a grade of "0" unless you have an absence approved by your recitation instructor. At the discretion of your recitation instructor you may be assigned extra credit homework on paper or PhGradeAssist2 which will count toward your recitation grade or practice assignments and tests on the computer GradeAssist2 system which will not be counted toward your recitation grade.
One of the best ways to do your homework is to form a homework study group with your friends and work on problems together. Each of you, however, must submit your own individual solution for each problem set to your recitation instructor by the due date. Working as a team will help you to improve your understanding as well as your grade.
To use the PhGradeAssist2 system for practice homework and/or homework extra credit work you must have access to a computer connected to the internet either at your residence or on campus at UML North or UML South Tutoring Centers. First, go to the course website, go to the Materials page and click on PhGradeAssist2. Select Student Login and create a profile with your personal User ID purchased with your course materials and a password. Enter your ID and password. Select the assignment your want to work on by clicking on it. Follow the directions given on the website to complete, submit and have the assignment corrected with feedback on errors.
You should follow the homework format below for the paper homework assignments (instead of PhGradeAssist2 exercises) to make it easier to grade your work accurately and to develop your problem solving ability.
1. Do your homework on 8 1/2 x 11 in. sheets of paper.
2. Your name (last name first) should be printed in the upper left hand corner of each page along with the date, assignment no., course no. and section no.
3. You should place the problems in the numerical order assigned.
4. Include a suitable diagram, correctly labeled with the given information as well as the quantities to be determined for each problem.
5. You should first write equations representing the fundamental principles of physics which apply to each problem in terms of symbols before attempting a solution.
6. All the mathematical steps necessary for the derivation of a formula for the problem should be written in terms of symbols, algebraically simplified, checked for the consistency of units, and then the given numbers substituted to obtain a numerical solution with the correct units.
7. The solutions for the odd numbered problems can be found in the solution manual, but you should first try to solve them yourself.
8. If you are asked to make a graph, it should be done using either a computer plot package or by hand neatly on graph paper.
9. You must staple all the pages of a single assignment together in order in the upper left hand corner before turning in the assignment. (If two assignments are collected on the same date, they should be kept separate.)
7. QUIZ POLICY
Your recitation instructor will typically give at least one ten to fifteen minute quiz per week. This quiz may be announced or unannounced and will cover recent material similar to the homework problems. You must come to class prepared with a pencil, eraser and calculator. Your two lowest quiz grades will be counted as dropped by your recitation instructor. Unexcused absences will result in a quiz grade of "0" for that particular quiz. No make-up quiz will be given.
8. ATTENDANCE/ABSENCE AND DISABILITIES POLICIES
Your attendance is required at all lecture, recitation and laboratory classes. Attendance will be taken in lectures using your responses for the PRS system and in recitation classes, quizzes can serve as proof of attendance. Poor attendance in either lecture or recitation classes will lead to a drop in your grade.
YOU ARE NOT ALLOWED TO ATTEND ANY CLASSES UNLESS YOU ARE OFFICIALLY REGISTERED IN ISIS FOR 95.144,PHYSICS II OR 95.164, HONORS PHYSICS II.
There are no make-up examinations for EXAM I, II or III. Illness on the day of an examination must be verified by submission of a letter from a physician or nurse to your recitation instructor showing that you were seen prior to or on the day of the examination and attest that your illness made you unable to take the examination. Notification of all other absences, i.e. varsity sports, family events, etc. must be made one week in advance by written request and approved by your recitation instructor.
Only one EXAM I,II or III absence is allowed which is approved by your recitation instructor. In that case your course grade will require increased emphasis on the FINAL EXAMINATION (See item 9). If you are unable to take the FINAL EXAMINATION for a reason acceptable to your recitation instructor, you may request in writing an incomplete grade for the course within 48 hours of the FINAL EXAMINATION (See the Undergraduate Catalog for the procedure). Your recitation instructor will calculate your grade as if your FINAL EXAMINATION grade was "0" and submit both the incomplete grade "I" as well as the calculated grade which will become your permanent grade for this course if a make-up FINAL EXAMINATION is not taken by the deadline for incompletes. (See the University Calendar).
If you have either a learning disability or a severe physical handicap, you may
be eligible for extra time during the EXAMS and the FINAL. Discuss your
situation with the
For 95.144 students your grade is based on the total number of points you earn during the course. The maximum number of points you can earn is 700 which is broken down as follows:
30 pts. Lecture Attendance & Participation
170 pts. Homework(85) & Rec. Quizzes(85)
100 pts. EXAM I
100 pts. EXAM II
100 pts. EXAM III
200 pts. FINAL EXAM
700 pts. TOTAL
For 95.164 students your grade is based on the 700 points above plus an additional 100 points for a power point presentation which you will give at the end of the semester.
Remember, in evaluating your homework and quiz scores the two lowest homework and quiz grades are dropped. If you are excused from EXAM I, II or III, the FINAL EXAMINATION will count 300 pts. If you have six or more unexcused, recorded absences in either recitation or lectures, your course grade may be reduced by one step in the letter grade scale.
At the end of the semester after all grades including the FINAL EXAMINATION are added together your lecture instructor in consultation with all the recitation instructors will determine the points required for the various letter grades. As a rough estimate of your performance as you progress through the course the following conversions between your percentage score at a given point in the course and your letter grade are listed below:
A 80% - 100%
A- 77% - 79%
B+ 75% - 76%
B 65% - 74%
B- 62% - 64%
C+ 60% - 61%
C 50% - 59%
C- 47% - 49%
D+ 45% - 46%
D 35% - 44%
F 0% - 34%
* (The final conversions determined at the end of the course may differ slightly from those listed above.)
Make sure you do not sacrifice points needlessly by missing lectures, homeworks and quizzes.
You will be given a separate grade for the laboratory course 96.144. How this grade is determined will be explained by your laboratory instructor.
10. HELP IF YOU HAVE A PROBLEM
