Section 2: MWF 12:30pm-1:20pm in Nicholson 119

Office hours: M 1:20pm-2:20pm, T 4pm-5pm in Nicholson 447 (please email before coming)

Course Syllabus

Textbook: Fundamentals of Physics, by Halliday, Resnick, and Walker, 10th edition (Wiley).

Homework: A homework assignment will be assigned each week using WileyPlus www.WileyPlus.com. (See email sent out for detailed instructions.) If you previously purchased a WileyPlus access code for this edition of the textbook, it should work this semester with no additional fee. Homework will be due on Sundays at 11:45pm. WileyPlus is a very stable system, but on rare times there can be glitches. Do not procrastinate. Extensions will not be granted on homework assignments, but you can complete the assignment anytime after the due date for 80% credit. You are encouraged to work together with other students on homework, but the work you submit should be your own. It is most important that you understand the homework, given that it will appear on quizzes and exams. The homework will be divided into two parts: problems and multiple choice concept questions. For all homework problems, you have 5 attempts for full credit.

Tutoring: Free physics tutoring is offered in Nicholson 102 and Middleton 141. The hours are posted here. Up to 900 minutes of free online tutoring offered here through your PAWS account. Academic Center for Student-Athletes, Student Learning Program and free tutoring in Tutorial Center.

Mid-term exams:
Exam I: 6:00-7:00PM TUES 24 SEP 2019
Exam II: 6:00-7:00PM TUES 22 OCT 2019
Exam III: 6:00-7:00PM TUES 19 NOV 2019

Calculators: During your test, the only electronic device you may have with you at your seat is a scientific or graphing calculator. You may not use the calculator app on your smartphone or tablet. You may not have your cell phone, tablet, smartphone, 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 also not close enough to you that you could reach it during the test. Any student found with such a device during an exam will be assumed to be violating the LSU Honor Code and will be referred to the office of Student Advocacy & Accountability. In addition the device will be confiscated.

Final Exam: 7:30-9:30AM MON 09 DEC 2019
