Course Goals
General Education Areas
This course satisfies URI's general education areas: "Scientific, Technology, Engineering, and Mathematical Disciplines" (Full); and "Mathematical, Statistical, or Computational Strategies" (Partial).
Learning Outcomes
Course Web Page: A course web page has been set up at the following url: https://penrose.uri.edu/DaveH/Courses/PHY203/PHY203syllabusS20.html. From links in the syllabus, exam solutions, and old exams and lectures can be accessed on the web. Exam grades will be posted on Sakai.
Sakai: The class will use Sakai for important announcements and posting exam grades.
Examinations: There will be three unit exams and a final exam. These exams are closed book. Calculators will be permitted. The unit exams will consist of 3 problems with multiple parts. The final will have 9 problems. You will be provided with a sheet of paper containing relevant formulas for each exam and 3 sheets for the final. The dates of the exams (in class during class time) and time for the final exam are listed below. If you miss an exam for any reason, the final exam will act as a makeup. Exam solutions will be linked from the course web page. Exam grades will be posted on Sakai.
Course Units: The course is divided into three units as follows:
unit #1 Chaps. 1-3 exam on Fri. 2/14
unit #2 Chaps. 4-7 exam on Fri. 3/20
unit #3 Chaps. 8-10,14 exam on Mon. 4/27
Final Exam Friday, May 1, 3-6 pm
Final Exam: The final exam will be divided up into three sections corresponding to the three units of the course. If the score on a unit exam is lower than the score on the corresponding section of the final exam, the score on that section of the final exam will replace the unit exam score when your semester grade is calculated. Every student must take the final exam.
Quizzes: I will ask from one to several questions in every class that must be answered electronically using the "TopHat" personal response system. You can answer with a laptop or tablet or by smartphone (after downloading an app) or by texting in the answer. You must register on TopHat ("Sign-up" at tophat.com) and also put in your cellphone # (if you want to be able to text in answers). For each question, just submitting an answer will earn you 1 ("participation") point. A correct answer an additional 1 point. If you earn 75% of the maximum points at the end of the semester, you will receive full credit for the quizzes. The "join code" is 371681
. The phone number for texting in answers is (315)636-0905.
Homework Assignments: A set of homework problems will be due on or before usually Wed. of almost every week (by 11 p.m.) and will be administered through a web-based system called WebAssign (see below).
Problem Sessions: Approximately once per week on most weeks we will do worksheets and problems involving group work in class instead of a lecture. At least one question using TopHat will be asked during each session. You can miss one of these classes with no penalty.
unit exams 400 points
final exam 400 points
homework 100 points
recitation 100 points
problem sessions 50 points
lecture quizzes 50 points
Grading Scheme:
A(93-100); A-(90-93); B+(87-90); B(83-87); B-(80-83); C+(77-80); C(73-77);

WebAssign:
· Homework will be administered through a web-based service named WebAssign. Exam grades will also be posted here.
· WebAssign can be accessed at http://webassign.net/student.html
o The Class Key for WebAssign for this course is: uri 2562 3855
· Students will enroll with this class key, creating their own user IDs and password. When they go to the login page, they simply click the box saying "ENTER CLASS KEY".
· When you first log on you will be asked for your access code, which will be packaged with the textbook, which is available in the URI Memorial Union bookstore.
· You will have 5 chances to submit your homework solutions before the due date.
· In WebAssign each student gets a different set of numbers in the problems, so the answers will be different.
· There is a 2-week (free) grace period for you to get started.
Recitation:
· All students must also register for a recitation section of PHY273.
· The recitation meets once a week (for one hour in Room 112).
· Your recitation grade will be counted toward your PHY203 grade up to a maximum of 100 points. There is no separate letter grade for the recitation of PH273.
· You must attend the recitation section in which you are enrolled. You will not get credit in another section.
· You must correctly solve 3 problems in each recitation section to get full credit for the class. Extra solved problems one week will count towards any missed problems (or a missed session) in other weeks. Extra problems solved will not count for additional extra credit beyond the maximum of 100 points.
Course Assistance
· Physics students are often available in East Hall, Room 216, to provide help.
AEC tutors are students like you who have succeeded in this course and understand how challenging it can be. They can answer questions, clarify concepts, test your understanding, and show you how to study in the most effective ways possible.
You can make an appointment or walk in anytime during office hours -- Monday through Thursday from 9 am. to 9 pm, Friday from 9 am to 1 pm, and Sunday from 4 pm. to 8 pm. For a complete schedule -- including when tutors are available specifically for this class -- go to www.uri.edu/aec, call (401) 874-2367, or stop by the fourth floor in Roosevelt Hall.

PHY273: LABORATORY POLICIES
Registration
Each student registered for PHY203 must also register for two sections of PHY273. Register for one of 000x sections for laboratory, and one of R0x sections for recitation.
You must purchase a Laboratory Notebook prior to your first meeting, and bring it. See below for the description of the Lab Notebook. The Laboratory Manual is sold in the bookstore. Both the Lab Notebook and the Lab Manual are required for this course.
Make-up Labs
You must complete every one of the experiments. Otherwise, you will receive zero points for the experiments missed. If you have a legitimate reason to miss a laboratory session, you may ask in advance permission from the TA to participate in another laboratory section. There will be only one make-up class available at the end of the semester.
Final Lab Exam
A final exam for the lab course will be given at the end of the semester. The exam will count for ~8% of the total lab grade.
Laboratory Schedule
Each of the PHY273 laboratory sections meets once a week for two hours in East Hall Room 102. You will be conducting five experiments over 10 weeks. See specific dates below:

Conducting a Laboratory
At the beginning of each experiment, the teaching assistant (TA) will give a brief introduction to the relevant material (the goals, physical principles, measurement techniques, data analysis, error estimate) and explain how to handle any particular piece of equipment.
It is not the TA's duty to set up, perform, analyze or interpret experiments for the students. While the work on the experiment proceeds, the TA will circulate among the students, look over their shoulders, and with leading questions, help them understand what they are doing. However, it is the students' responsibility and obligation to ask questions about any aspect of the experiment or the underlying physics which is unclear to them.
Make sure you know your TA's name, email address, and office phone number, so you may contact her/him later when you need more information.
Laboratory Manual
The PHY273 Laboratory Manual contains detailed descriptions of all scheduled experiments. You are expected to read the Lab Manual before coming to conduct your experiments. The manual is on sale in the URI bookstore.
Laboratory Notebook
You must bring a Laboratory Notebook that is quad-ruled for graphs and has sequentially numbered pages and pages bound to stay. Spiral notebooks or notebooks without page numbers are not acceptable. The URI bookstore sells a Computation Notebook for ~$15 (Avery-Dennison, #43-648). You may use this same notebook in subsequent semesters for PHY274 and PHY275.
For every one of the five experiments, observations, data, graphs, calculations, interpretations, and conclusions must be recorded in the Lab Notebook. Do not remove pages under any circumstances. If you make a mistake in writing, simply cross it out, and make corrections in the next available space. You are allowed to paste printed graphs and tables into the Lab Notebook pages.
Note: You must complete your writing in the Lab Notebook while you are in the laboratory. Your performance in the PHY273 Lab will be evaluated on the basis of your Lab Notebook. There will be no other written reports.
Keeping the Laboratory Notebook
During the first session of each experiment, you will record pertinent information, set up tables, sketch the equipment, perform the experiment, gather data, and begin a preliminary analysis. Use your time in the laboratory efficiently. Do not leave the laboratory before the session is over. You may take the Lab Notebook with you when you leave the first session, for your own study.
During the second session of each experiment, you will usually perform a more detailed analysis of your data, compare your results with other groups' results, and participate in class discussion of your results. For some experiments, you will also conduct computer simulations. You will record all pertinent information in your Lab Notebook during the session and hand in your Notebook to your TA before you leave the room. You cannot take the Lab Notebook home with you after the second session. The TA will grade your Notebook and return it to you before the next experiment.
For each experiment, your Lab Notebook must include the following items:
(a) A sketch of the apparatus with significant dimensions indicated and a brief description of its purpose.
(b) The data taken from measurements recorded in tabular form including the appropriate units.
(c) Graphs (histograms or line graphs) appropriately labeled and accompanied by explanatory captions.
(d) An estimate of the expected error of each observation and a statement of how these errors affect the uncertainty of the final result.
(e) A discussion and interpretation of the results obtained in light of the goals of the experiment.
Grading Scheme
The evaluation of each entry in your Lab Notebook will be based on the following five items:
(a) descriptions, definitions, and sketches (20 pts)
(b) data tables (20 pts)
(c) graphical representation of experimental data (20 pts)
(d) error estimate (20 pts)
(e) interpretation and conclusions (20 pts)
These items do not necessarily represent separate sections in the Lab Notebook. However, each item must be present conspicuously. Each item will be awarded up to 20 points for a total of 100 points per experiment
The letter grade for PHY273 lab will be calculated by your total number of points divided by 5. There will be no additional scaling of grades.
A (93 or higher) A- (90-93) B+ (87-90) B (83-87) B- (80-83)
C+ (77-80) C (73-77) C- (70-73) D+ (67-70) D (60-67)
F (60 or lower) NW (No submission of work)
