More information is available in Canvas on the Quiz Instructions page.
Final Examination: Saturday, May 8, 2021 (tentative); to consist of 4 back-to-back quizzes that cover the course material cumulatively.
General Information:
This course is the second course of a two-semester introductory physics sequence for science and engineering majors. It covers the branch of physics known as electricity and magnetism, which is the study of electrical and magnetic interactions of electrical charges and currents. The class focuses on electromagnetic phenomena and strives to teach the students to use fundamental principles to solve quantitative problems involving fields, conservation principles, forces, and motion. The course is writing intensive and includes required discussion and laboratory components.
The course has an essential laboratory component, with a report-writing and grading requirement which allows it to serve as a writing-intensive class and, when passed at the level of 60% or better, to successfully meet the requirements for U of Minnesota’s writing-enhanced curriculum. If you do not pass the laboratory component at 60%, then you will fail the course, regardless of your performance in other components of the course.

REQUIRED MATERIALS
Textbook: Halliday and Resnick - Fundamentals of Physics, 11th Edition, by Jearl Walker. An e-text is provided with Wiley’s Inclusive Access purchase.
Supplementary Texts (optional): The Competent Problem Solver for Introductory Physics, University of Minnesota, School of Physics and Astronomy - downloadable pdf file on the course website. Any trigonometry/algebra/calculus texts will do if you need a refresher in these mathematical concepts.
Lab problems can be found under your specific lab section listed on your Canvas Dashboard.
Lab Journal: A gridded notebook, e.g., U of MN 2077-S, which is available from the bookstore, will be required.
Lab Kit: This must be ordered from the bookstore. It contains materials to carry out labs at home.
Ti-30xa Calculator or other simple scientific calculator. These are the only types of calculators that will be permitted during quizzes and the final exam. No graphing calculators are permitted.
STUDENT RESPONSIBILITIES
Attend all lectures, discussions, and lab sections.
Before each lecture:
• Read the relevant sections of the text. The lecture will not cover everything the book does, and you’ll be responsible for knowing the assigned material whether or not it’s covered in lecture.
• Be prepared to attend the lectures via Zoom at their scheduled times. You will be answering short questions via Chime In in Canvas (see instructions below) during each lecture. This will determine the class participation part of your grade.
Before each lab meeting:
• Read the Introduction, Objectives and Preparation sections of the write-up in the Lab Manual for the problems assigned for that week. Answer the Pre-Lab questions for the labs listed in the Table below and submit these on your lab page in Canvas. You will not be able to submit your lab data and analysis without having turned in your Pre-Lab questions. For the lab assigned for the week, get into the habit of (i) answering your pre-lab questions and uploading your answers on your Canvas lab page and (ii) setting up your lab before your scheduled lab meeting.
At each lab meeting:
• Start your lab, take data, and upload data record and analysis as well as answers of your post-lab questions shortly after the lab, per instructions provided by your TA.
Before each discussion:
• Complete the relevant homework problems as essential preparation for the group discussion.
• You’ll be solving problems as a group in the discussion section, so study up on the textbook and review lecture material in advance. Make sure you’re ready to contribute to the group. Your TAs are watching your participation!
Homework assignments:
• Assigned in Canvas via WileyPLUS on Mondays and due on Thursdays by 8 am before your discussion each week (except the first week – short assignment due on Friday by noon).
CHIME IN INSTRUCTIONS
Chime In will be administered via Canvas as an Assignment called Class Participation. Go to your Canvas page, go to Assignments, and click that assignment before the start of each lecture. There will be 1-2 Chime In questions per lecture. Keep the link open and be ready to answer the questions when I open and display them.
MATHEMATICS
21st century physics is highly dependent on mathematical models for quantitative results. Success in Physics 1302 will require you to develop and apply mathematical skills. The most important skill is the ability to describe a physical context in terms of a mathematical model. Geometry and trigonometry are particularly important. Modeling dynamically changing systems will require differential calculus. Aggregating individual effects will utilize integral calculus. If you are taking Calculus I or II concurrently, you will likely encounter some mathematical techniques in physics before you see them in your math class. For that reason, Physics 1302 will include some topics in mathematics, particularly in differential, integral and multivariable calculus and differential equations.
WORKLOAD:
This is a demanding course. There is a lot to learn, and we move at a fast pace. Since each new topic builds on previous work, it is of great importance (more so than for most courses) that you do not fall behind. You should expect and plan for a workload consistent with University policy (3 hours per week per credit for a total of 12 hours per week for an average student to receive an average grade). In particular, it is essential to complete your homework assignments in a timely manner not only for their impact on your grade but to also stay caught up with the course material needed for weekly discussion problems, quizzes, and labs. The lecture can only cover some basic problems to introduce the concepts, but homework problems reflect better the challenging problems that you will be tested on.
DISCUSSION SECTIONS
In your discussion section every Thursday, you will work with classmates to solve 1-2 challenging problems in small groups under the supervision of your TA. Your group will solve those problems collaboratively with all group members. You must attend, as your group depends crucially on your participation for solving discussion problems. Penalty for non-attendance is heavy - each absence might lead to a 10% deduction on your quiz that follows.
LABORATORY SECTIONS
You will have the same TA and work in the same group as in your discussion session. Labs are designed to give you an opportunity to test, expand and refine your understanding of basic physics concepts. Careful recording of observations in your lab journal and preparation of formal lab reports are important parts of this experience.
Because this course satisfies University requirements as a laboratory science class and as a writing intensive course, you must receive a minimum laboratory grade of 60% to receive a passing grade in the course. The laboratory grade will be based on the demonstration of well-organized laboratory reports, well thought out predictions and answers to the questions in the laboratory manual brought to class, and collaborative skills as evidenced by effective group work. Failure to participate in the laboratory will result in a laboratory grade of 0 for that topic. There are no make-up laboratories, except in situations officially recognized by the University. In that case, the laboratory work must be made up by arrangement with your TA before your next scheduled laboratory period. Grades for the laboratory work will be determined in part by laboratory reports, in part by your work during each class and in part by your work in answering the warmup questions and predictions. The predictions and questions assigned by your TA must be turned in no later than 24 hours before the laboratory time each week.
Your TA will check your lab notebook often to ensure you are keeping a good record, but not every lab will be turned in for grading. The lab reports that will be turned in and graded are assigned by your instructor (i.e., me) every 3 weeks on Fridays by email. Reports should be no longer than 6 nor shorter than 3 typed pages (using a word processor is required and such facilities are supplied by the University), including all necessary predictions, graphs, data tables, and calculations. Reports must be uploaded to your Canvas laboratory course page for grading no more than one week after they are assigned. Late reports will not be accepted. Graded reports will be returned to you at your next laboratory meeting. Your first report (and only the first one) may be revised based on instructor comments to achieve a higher grade. The revised report must be given to your laboratory TA at your next lab if not sooner, to be regraded and returned to you at your next lab. Details of the laboratory grading are in your laboratory manual. Remember this is a writing intensive course so your grade will depend on your written communication skills.
COURSE GOALS AND OBJECTIVES
This course satisfies a number of the Univ. of Minnesota Student Learning Outcomes (SLOs) presented at http://academic.umn.edu/provost/teaching/cesl_loutcomes.html
● To be able to identify, define, and solve problems
○ Students will be asked to solve a variety of physical problems in class, on their homework, in lab, during their discussion sessions, and on exams.
○ Even though this course specifically will require students to apply a few natural laws and the abstractions of mathematics to describe diverse physical systems, students will learn general problem solving strategies that will be valuable to many of their future academic and career endeavors.
● To have mastered a body of knowledge and a mode of inquiry.
○ In this course, students will consider the general topics of electricity and magnetism. The fundamental principles of electricity and magnetism are explored and the application of these physics concepts in modern technology is emphasized.
○ Problems exploring these topics will be addressed in a variety of ways as they are presented in many different formats; investigations employing experimental apparatus will be carried out in the lab component of the course; groups of students will consider context-rich problems during the discussion sessions; and students will work through homework sets that will develop a strong foundation in parsing information from text and discussions.
● To be able to communicate effectively
○ During lab sessions, students must form an argument, through data presentation and analysis, that they have successfully probed some physical topic.
○ Student groups will orally present and justify the results of physical questions that they have just explored in discussion sessions.
○ On exams, students must provide, in a well-reasoned manner, solutions to short answer problems.
● To understand the role of creativity, innovation, discovery, and expression across disciplines
○ Students will explore how the physical concepts discussed in this course were developed empirically and how these concepts have been applied to various systems yielding, e.g., much of today’s technology.
○ As a physics course geared toward students in the natural sciences and engineering disciplines, students will explore how the concepts broached in this course relate to the physical world and modern technologies by solving broadly relevant problems.
● To have acquired skills for effective citizenship and life-long learning
○ The ability to think critically about problems that is nurtured in this course is relevant not only for one’s academic and career development but also is a vital component of a well-rounded individual.
ATTENDANCE POLICY
Attendance to lab and discussion sessions, via zoom meetings during their scheduled times, is mandatory.
Missing a discussion session will result in 10% deduction on the quiz the following week.
Failure to attend lab without a valid excuse will result in the loss of points for that day’s lab assignment. If you must miss a lab section, then please make arrangements with your TA in advance to attend another lab section, if possible.
Lecture attendance is strongly encouraged and will count, via Chime In poll, toward a lecture participation grade.
GRADING
Your course grade will be based on the following components:
Lecture Participation: 5% (only 80% of maximum Chime In points to count)
Homework: 10%
Laboratory: 20% (NOTE: you must pass the lab with a score of 60% or better to pass the course.)
Scores of the best 6 out of 7 biweekly quizzes: 42% (= 6 x 7%)
Final Exam: 23%
Homework is assigned each week via WileyPLUS in Canvas.
The lab grade is based on pre-lab questions, TA evaluation during lab, and post-lab "Apply Your Knowledge" questions. All these are provided on the lab-specific Canvas course site.
Upon calculating your final numerical grade, you will receive a letter grade of:
|
|
A :≥ 90 %
|
A − :< 90 % or ≥ 85 %
|
|
B + :< 85 % or ≥ 80 %
|
B :< 80 % or ≥ 75 %
|
B − :< 75 % or ≥ 70 %
|
|
C + :< 70 % or ≥ 65 %
|
C :< 65 % or ≥ 60 %
|
C − :< 60 % or ≥ 55 %
|
|
D + :< 55 % or ≥ 50 %
|
D :< 50 % or ≥ 45 %
|
F :< 45 % or lab < 60 %
|
Resolving grading disputes: If you are dissatisfied with a lab or discussion grade or have related issues, address them to your TAs. For more general grading issues, express your complaint in a well-written email addressed to Prof. Prasad. Individual quiz scores may be rescaled ("curved") at the end of the semester if deemed appropriate. You will be notified if this is the case.
LIBERAL EDUCATION CORE
This class satisfies the University of Minnesota Liberal Education requirement of a physical science course with a laboratory component, as part of the Liberal Education Core. The class exposes the student to physical principles and concepts, demonstrates how these principles can be applied to quantitatively describe natural phenomena, and provides the student with an opportunity to perform hands-on experiments and measurements that model how physical knowledge is obtained. The class develops the use of fundamental principles to solve quantitative problems regarding motion, forces, conservation principles, electric and magnetic fields, structure of matter, and their applications to electromagnetic phenomena. The development of conceptual understanding of physical principles and their quantitative application are further deepened in the discussion section, where students practice problem-solving skills in small groups.
Because all knowledge in the physical sciences is empirically acquired, the laboratory component of the course is essential to properly expose students to the scientific method and the ways of knowing and thinking in the physical sciences. The lab component involves the formulation of scientifically sound predictions by the student, followed by empirical testing of the hypotheses through hands-on experimentation. Since the language of the physical world is mathematical, quantitative analysis of experimental data is an essential aspect of the lab experience. Physics, like all sciences, is a social endeavor, and students are exposed to cooperative problem solving, working in small groups with other students, in both the laboratory and discussion sections of the course.

An incomplete requires extraordinary circumstances as an excuse for not completing the course on time. It requires a written and signed agreement between the professor and the student, which is placed on file with the Physics Department. You cannot retake a major portion of the course through an incomplete."
ATHLETES must provide, either by email or in person, their official University of Minnesota athletic letter containing the approved competition schedule to their instructor and the staff ([email protected]) in the physics office (Tate 130). Accommodations will be made for official university sports only (i.e. no accommodations will be made for intramurals, club sports, etc.)
DISABILITY SERVICES (DRC): If you have accommodations for this course, please provide the staff in the physics office (Tate 130) with a copy of your accommodation letter for the current semester. Exams will be arranged according to accommodations and sent to the testing center for administration.
PRIVACY: Minnesota privacy laws require that tests and other materials are returned in a manner that ensures that no one else can see your grades. Papers will be handed out at the first recitation after grading is completed.
ACADEMIC INTEGRITY
All work that you turn in for a grade must be your own. The following behaviors are considered to be cheating:
• Using the responder (clicker) registered to another student in this course
• Copying all or part of a lab report, data table or fabrication of data (see Intro, pg. 3 of Lab Manual)
• Copying all or part of a quiz or final exam from another source
• Any other matter covered by the University statement below.
Your TAs are observant! They notice duplication in lab reports and cheating on exams.
MANDATORY STATEMENT ABOUT ACADEMIC INTEGRITY
The University expects the highest standards of honesty and integrity in the academic performance of its students. Any act of scholastic dishonesty is regarded as a serious offense, which may result in expulsion. Scholastic dishonesty is defined as plagiarizing; cheating on assignments or examinations; engaging in unauthorized collaboration on academic work; taking, acquiring, or using test materials without faculty permission; submitting false or incomplete records of academic achievement; acting alone or in cooperation with another to falsify records or to obtain dishonestly grades, honors, awards, or professional endorsement; altering, forging, or misusing a University academic record; or fabricating or falsifying data, research procedures, or data analysis. Aiding and abetting an act of scholastic dishonesty is also considered a serious offense with the same possible consequences. Students may not make commercial use of their notes of lectures or University-provided materials without the express written consent of the instructor. (See the Senate policy at: http://policy.umn.edu/education#Education.
Academic dishonesty in any portion of the academic work for a course shall be grounds for awarding a grade of F or N for the entire course. See http://regents.umn.edu/policies/index
