Other calculus-based physics texts are acceptable but it will be difficult to be successful without a text. COURSE TOPICS: This course will introduce the laws of motion, inertia, acceleration, force, energy, momentum, angular momentum, conservation laws, rotational and oscillatory motion, gravitation, and thermodynamics. (see schedule). Course announcements and other information will be posted on Canvas. Attendance/Participation: You are expected to attend all lectures and recitations for the section in which you are enrolled; your grade will depend upon your attendance and participation in class. Absences: Pop quizzes (10 pts) will be given at least once a week on material covered in the classes since the last pop quiz (5 points for attendance and 5 points for correct answer. Final course score for quizzes will be calculated as a percentage of the points earned. Each student is responsible for all material covered in class. Exams: THERE WILL BE NO MAKEUP EXAMS. Exam questions will be based on lecture material, material contained in the text and in the homework assignments. Four(4) 80-minute exams will be given during the semester and a 2-hour comprehensive final exam (10:30 AM - 12:30 PM on Tuesday, 7 May) will also be given. The lowest exam grade will be dropped and highest three exam grades will be used to calculate the course grade. The final exam will consist of equal portions from each of the regular exams plus any material covered after the last regular exam. If one (1) regular exam is missed, that exam will count as the lowest exam grade and will be dropped. A second missed exam will be given a score of zero(0) unless a valid excuse is accepted by the instructor. The grade for the excused second missed exam will be determined by the percentage correct of the problems on the final exam relating to that particular exam.* If more than two exams are missed, grades of zero will be given for the additional exams.

The University of North Texas makes reasonable academic accommodation for students with disabilities. Students seeking reasonable accommodation must first register with the Office of Disability Accommodation (ODA) to verify their eligibility. If a disability is verified, the ODA will provide you with a reasonable accommodation letter to be delivered to faculty to begin a private discussion regarding your specific needs in a course. You may request reasonable accommodations at any time, however, ODA notices of reasonable accommodation should be provided as early as possible in the semester to avoid any delay in implementation. Note that students must obtain a new letter of reasonable accommodation for every semester and must meet with each faculty member prior to implementation in each class. Students are strongly encouraged to deliver letters of reasonable accommodation during faculty office hours or by appointment. Faculty members have the authority to ask students to discuss such letters during their designated office hours to protect the privacy of the student. For additional information see the Office of Disability Accommodation website at http://www.unt.edu/oda. You may also contact them by phone at 940.565.4323. UNT’s policy on Academic Dishonesty can be found at: http://www.vpaa.unt.edu/academic-integrity.htm Drop information is available in the schedule of classes at: http://registrar.unt.edu/registration/schedule-of-classes The Student Perceptions of Teaching (SPOT) is a requirement for all organized classes at UNT. This short survey will

be made available to you on-line at the end of the semester and will provide you with an opportunity to provide

feedback to your course instructor. SPOT is considered to be an important part of your participation in this class. In

addition to SPOT, there will be a brief in-class course survey during the last two weeks of the semester.

Near the end of the Spring 2019 semester you will receive an email on from "UNT SPOT Course Evaluations via

IASystem Notification" (no-reply@iasystem.org) with the survey link. Please look for the email in your UNT email

inbox. Simply click on the link and complete your survey.

After logging in to the my.unt.edu portal, students can access the SPOT survey site by clicking on the SPOT icon. A list of their currently enrolled courses will appear. Students complete each course evaluation independently. During the long terms, the SPOT is open for students to complete two weeks prior to final exams. During the Fall term, the SPOT is open for students to complete six days preceding their final exam. See https://spot.unt.edu/content/fall-2017-8w1-calendar for specific dates and deadlines.

Physics 1710 Core Objectives

This course satisfies the core course requirement by achieving four core objectives: (1) Critical thinking - analysis, evaluation, and synthesis of information. (2) Effective communication - development, interpretation, and expression of ideas through written, oral, and graphical. (3) Quantitative skills - the ability to compute and manipulate quantitative data and to reach meaningful conclusions. (4) Teamwork - the ability to consider different points of view and to work effectively as a team.

Physics 1710 Goals and Learning Strategies

The goals of instruction in Physics 1710 are to lead and to guide you to master the fundamentals of elementary classical mechanics and thermodynamics, to construct in yourself a fundamental understanding of these topics, to develop your skills of analysis using the mathematical tools of algebra and calculus, and to cultivate an interest in and an appreciation for physics in nature and in the human experience To help in achieving these goals you are requested to pursue the following strategies:

(1) Read the text chapter within the forty-eight hours prior to the class. You should bring your questions to class or e-mail to the instructor prior to the morning of the class.

(2) During class, listen, observe, take notes, analyze, discuss with peers, answer questions, solve in-class problems as directed by your instructor.

(3) Review your textbook chapter summary and your notes (for best results, re-copy your notes) within twenty-four hours after class.

(4) Work the assigned problems only after you have read and reviewed the material of the chapter. (5) Respond via e-mail to gaglass@unt.edu or during office hours whenever you have an observation or question. (6) Come to class prepared: It is highly recommended that you bring a calculator and your text book to take full

advantage of the lecture hall learning experience. Support Please note that some problems in any given assignment may not be for credit. You can identify which problems are for credit by looking at the point value immediately after the problem number. The problems assigned zero credit are for your extra practice if you choose to take advantage of them, which you are encouraged to do. Homework grading policy:

a. The computer-generated score is will constitute 5% of the total homework grade. b. Homework posted to Blackboard must have complete solutions to retain the credit. For each such problems,

the grader will verify that: i. Your solution is neatly written; ii. there is an explanation of the problem’s solution in your written work; iii. the solution presented is reasonable, i.e., essentially correct as shown; iv. there is sufficient detail in the explanation to allow someone to understand all the steps of the solution.

If these three conditions are clearly not met, then you will receive reduced or no credit for the problem.

Ancillary Materials Also available for your extra problem-solving practice is a text similar to the one used for this class, with a full set of solutions for all of the problems in the backs of the chapters. These materials are on reserve in the Science and Technology Library. A Help Room (location to be announced) is staffed weekday afternoons by a teaching assistant to assist you with questions regarding any aspect of the course, including homework assignments. Hours will be posted on the door of the Help Room, as well as at the beginning of lecture. TA contact information will also be posted on the Help Room Door.

NOTE: This document may be amended as needed.
