SYLLABUS:REQUIRED TEXT:
Fundamentals of Physics, by Halliday, Resnick, and Walker, 10th edition extended (Wiley).PREREQUISITES:
Grade of C or better in PHYS 2110; grade of C or better in either MATH 1552 or MATH 1553.CLASS OVERVIEW:
- This course covers chapters 13, 21–33 of your textbook. There are a few sections that will be omitted. This is the introductory course primarily for technical science majors (physics, chemistry, geology, or engineers). It extends the material from PHYS 2110 to discuss electrical and magnetic phenomena, electromagnetism, and gravitation, all arising from the idea of a physical “field.” It will build your problem solving skills and your ability to apply mathematical principles to describe nature.
- You are required to read the assigned textbook material before coming to class.
- Attendance at lectures is highly encouraged! The concepts and approaches to problem solving will be developed through the readings, lectures, demonstrations and class discussion. If you need to leave early, let me know ahead of time. To encourage participation, there will be daily in-class quizzes (see below)
- It is the student’s responsibility to be familiar with the University Code of Conduct that details the university’s policy and disciplinary action regarding academic dishonesty.
- Students with special needs or accommodations should contact the Office of Disability Services (112 Johnston Hall) early so that any necessary accommodations can be arranged ASAP.
QUIZZES:
Quizzes or other in class participation activities will be given in each lecture.
HOMEWORK:
- Homework is the most important part of the course!
- Homework is your physics “practice.” You will do well in the course if you do all the homework on your own since you will then be able to answer the questions and problems on the 3 tests and the final exam.
- We will use the Wiley Plus computerized homework system.
- The first 14 days are free (grace period). During this period, use Wiley Plus to do your homework.
- You can register with a credit card online or you can purchase a registration card at the LSU Bookstore. Ask at the Customer Service Desk. You can also buy web access to the text so you do not need to buy the book (see Wiley for details)!
- You will be given a maximum of 5 submissions. Only the last submission will be graded, no points off for multiple submissions. Your semester percentage score will be used in computing the homework contribution to your grade.
- Do the homework daily. Often the number of problems (20-30) is too large to do in one sitting. It is best if you do the homework the same day that the material is covered in class.
- Get in the habit of carrying the units through the solution from start to finish. Units are required as part of the answer and will definitely be required on the tests.
- Homework will typically be due on Thursday 11:59 pm. It will cover all of the material presented in lecture through the week. The Wiley Plus cutoff day and time is firm for full credit.
MIDTERM EXAMS:
- There will be three in-class tests (closed book) on material since the last test. Tests will consist of multiple-choice worked/concept questions and written worked problems. Because partial credit may be given, it is important that you show all work and give explanations and intermediate steps. An answer without showing the appropriate steps through a calculation will not be accepted.
- Greater than 50% of the exam problems will come from the assigned homework.
- Necessary constants and most formulae will be given on a formula sheet that will be given; it will be available before the exams.
- You will need a scientific calculator. You may not use a calculator app on your phone or on your tablet.
- During your test, the only electronic device you may have with you at your seat is a scientific or graphing calculator. You may not have your cell phone, tablet, smartphone, smartwatch, PDA, pager, digital camera, computer, or any other device capable of taking pictures or video, sending text messages, or accessing the Internet. This means not just on your person, but close enough to you that you could reach it during the test. Any student found with such a device during a test will be assumed to be violating the LSU Honor Code and will be referred to the Dean of Students for Judicial Affairs.
- There will be no make-up exams and no exam scores will be dropped from a student's grade. If you miss an exam and you have a valid and documented excuse, as per LSU Student Policy 22, you will be allowed to substitute the grade on that exam for the average of your other exam grades (midterm and final exams).
MIDTERM EXAM SCHEDULE:
- Exam I: 8:00–9:00PM MON 09 FEB in Cox Auditorium
- Exam II: 8:00–9:00PM MON 02 MAR in Cox Auditorium
- Exam III: 8:00–9:00PM MON 30 MAR in Cox Auditorium
FINAL EXAM:
- The two-hour Final Exam will be cumulative with extra emphasis (approximately 1/2 of the questions and problems) on material since the last test.
- Same format as the in-class tests with twice as many questions and problems.
- Same restrictions on electronic devices.
FINAL EXAM SCHEDULE:
Final exam is on May 9 from 10AM-12PM in the following location:PHYS 2113-1 (Gaarde) is scheduled to take their exam in Lockett 9
PHYS 2113-2 (Dowling) is scheduled to take their exam in Lockett 6
PHYS 2113-3 (Moreno) is scheduled to take their exam in Lockett 10
PHYS 2113-4 and 6 (Rupnik) is scheduled to take their exam in Lockett 5
PHYS 2113-5 (Beaird) is scheduled to take their exam in Lockett 15
GRADES:
Midterms - 100 points each Final Exam - 200 points Homework - 75 points In Class Quizzes - 25 points
TOTAL: Your numerical grade will be the total number of points you obtain, divided by 6.0.
Given your numerical grade, your letter grade will be at least the following:
