Section 021: Burger Fri 1:30pm – 3:20pm Monroe 155 ______________________________________________________________________________ Course Description: Continuation of PHYS A101 Introduction to Classical Mechanics. This course is a calculus-based survey of selected topics in classical electrodynamics, including electric fields & Gauss’s Law, electric potential; D.C. circuits, magnetic fields, electromagnetic induction, electromagnetic waves, reflection and refraction of light, and special relativity. Course Goals: This course will deepen the student’s understanding of electromagnetism and relativity as well as practice mathematical skills and provide new tools for problem solving. Students will acquire a general understanding of how physics theories emerged and became unified by discussing the historical background of the material.

Textbook: (Required) Physics for Scientists and Engineers, by R. D. Knight, Addison Wesley, 4th ed. We will cover chapters 22-32, 34, and 36. Other editions are fine, though you will need to watch out for changes in the chapter and section numbers. Class homepage: All of the handouts and grades will be posted on Blackboard. I will contact you by your Loyno email address. Online Homework: (Required) You need to get access to Mastering Physics (MP). Mastering Physics (MP) is used to administer the weekly homework assignments. Access to MP can be bought as a package with the text book, or separately (ISBN-13: 9780134067544). Both reading and regular assignments will be available through the MP website. You need to buy/register at MP as soon as possible. The course-Id that you need to register is MPBURGER3564102. More detailed instructions on how to register are provided at the end of this document, before the course schedule. If you are continuing from A101 Fall 2019, you do not have to pay any extra fees for accessing Mastering Physics i>clickers: Clickers will be used to assess class participation. It is absolutely essential that you get them soon, as points will be awarded based on your participation in the class using clickers. To register, go to www.iclicker.com/registration. Your student ID should be your loyno student id. Your i>clicker remote ID is found on the bottom of the back of your i>clicker remoter. If you have any further questions on clickers, please contact me.

Your Responsibilities: Reading Quizzes: Every week we will have a Reading Quiz posted on the Mastering Physics page

covering certain sections in the textbook that correspond with the material we discuss in lecture. It is in

your interest to look over the reading and take the Reading Quiz earlier rather than later because it will

help you come to class prepared, already knowing the terminology and some basic concepts.

o For each question, you can check your answers and resubmit until you get a question right;

there is no penalty for incorrect answers.

o There will be a penalty for late homework

Homework: I will assign homework sets about once a week. Homework sets are the intellectual

workouts we do to hone our skills and strengthen our brains. In the long term, we are training you to

think more like a physicist. In the short term, success on homework sets translates into success on

exams. Many problems will be challenging — don’t worry, this is normal. By consistently putting in

effort, you will be able to improve your skills and tackle these problems.

o Each homework assignment will have a forum on Blackboard to discuss issues and questions

with the assignments. Feel free to start a post or email me a question and I will post my answer

on the forum.

o For each question, you can check your answers and resubmit until you get a question right;

there is no penalty for incorrect answers.

o There will be a penalty for late homework

o Your lowest homework grade will be dropped.

Lab: There is an additional 1-credit lab component (PHYS A104) associated with this course that you will

need to register for separately. It has its own syllabus, which you will go over during your first class

meeting next week. You will be graded separately for the lab course.

Quizzes: Most weeks we'll have a quiz related to topics we've covered in the previous week. You will not

be allowed any notes, but all the necessary equations will be provided for you. The purpose of this is to

motivate you to memorize the essentials, so you'll always have them at your fingertips when attempting

more challenging material. There will be no pop quizzes.

o Your lowest quiz grade will be dropped.

o Makeup quizzes can be taken in my office.

Exams: Exams are where we evaluate your learning. Understanding your homework and quizzes will

prepare you for the exams. I will post a practice exam so you can prepare even more, if you so choose. I

will provide a formula sheet.

o There will be two midterm exams and a final exam.

Grading: Grade weights for the various components of the course will be as follows:

5% Reading Quizzes

20% Homework

20% Quizzes

30% Midterms (15% each)

25% Final

Your final grade letter will be determined by the following scale:

Grade A A- B+ B B- C+ C C- D+ D F

Cutoff 93 90 87 83 80 77 73 70 67 60 0

Attendance at all classes is expected. Not only should you be present, but you should be actively

engaged, having prepared with the reading and ready to ask any questions you have.

Absences and Extensions: The key here is communication. If you know you will be absent, email me and

we'll make appropriate arrangements. If there was an emergency, email me with the circumstances as

soon as possible.

Screen Policy: Screens, such as cell phones, tablets, and laptops can be a distraction and should not be

on during class time.

Students with Disabilities: If you have a disability and wish to receive accommodations, please contact the University’s Disability Services at 865-2990 (Student Success Center, Marquette Hall, Room 112). If you are eligible to receive test accommodations (e.g., extended test time) through the Student Success Center, you will need to give me an official Accommodation Form from Disability Services. For more information regarding disability services, please see http://www.loyno.edu/arc/disability-services

Academic integrity: Your classmates are your colleagues. I openly encourage collaboration on the homework. However, cheating on quizzes and exams will not be tolerated. You also may find the information at the Loyola WAC lab web site useful in understanding what is or is not plagiarism (http://loyno.edu/wac/handouts-and-helpful-links). A university operates based on trust and honesty. We, the course instructors, trust that you will do your work honestly and you, the students, should trust that we will evaluate your work honestly. I encourage a certain amount of discussion among students, but in physics you really don’t understand a concept and how to apply it unless you start solving problems on your own. Please keep that in mind when you study together. Tutors: Free peer-tutoring is available through the Student Success Center, (http://www.loyno.edu/arc/tutoring). Campus Closures: In case of campus closures/emergencies, announcements will be made as soon as possible via Blackboard and/or your loyno.edu email address. You also should check the Loyola University New Orleans homepage on the internet (www.loyno.edu). Should an emergency or an evacuation cause disruption of regular classes, instruction may continue via Blackboard. The course of action will be announced by me in coordination with the University. It is each student’s responsibility to check your loyno.edu email and assignments on blackboard within 48 hours of an evacuation. The Semester may be extended if it is necessary to make up class days due to emergency university closings. This information is available on the Academic Affairs web site:

http://academicaffairs.loyno.edu/students-emergency-responsibilities. Additional emergency-

planning information is also available - http://academicaffairs.loyno.edu/emergency-planning.
