PHY2020 Introduction to Principles of Physics

Class number 18897

Spring 2019

This is the syllabus for the in-class sections of PHY2020. There is also an online section of PHY2020, which is taught in a different manner with a different schedule. As you have chosen to take the in-class section, the teaching is based upon the fact that the students will be in the classroom three times a week for the entire semester. The HITT ("clicker") quizzes are an integral part of the grade. If you don't want to come to class, don't take it - take the online class!

Course Professor:

Prof. John Yelton

The Professor and Teaching Assistant from the online course know the course very well and are available at:Prof. Kevin Ingersent, NPB 2201, Monday 1 p.m. Ms. Shinjini Basu, NPB 2030, Tuesday 4 p.m. and Wednesday 3 p.m.

Text:Paul Hewitt, "Conceptual Physics", published by Addison-Wesley

Douglas Giancoli, "The Ideas of Physics", published by Brooks/Cole.

The textbooks are not obligatory. Note that these books are around in various editions. There are many copies available second hand in auction sites and online booksellers. We have deliberately chosen books that should not cost you a lot of money - $20 should buy a decent copy. In general the Hewitt book is more conceptual with words and pictures, whereas Giancoli is more formal and quantitative. Different students might find that they have different views as to which is preferable.

Preparation:High school math (basic algebra, geometry and trigonometry) is expected.

HITT Clicker Registration and Operation:During lectures, we will administer quick quizzes, which you will answer using your HITT remote control. When you respond to a question during class, you will see your remote ID number appear on the screen. The computer will store the response under the remote ID number, but it is up to you to tell us that is your remote ID by registering it at: http://www.phys.ufl.edu/~hitt/ When registering your remote, you

mustuse your UF email addressYourGatorlinkID@ufl.edufor e-mail. At the same web page, you will find instructions on which type of the remote control is acceptable and how it should be configured. It is your responsibility to ensure that your remote is functioning properly and that you are sending your response on the correct channel.

Setting your Remote to the correct frequency for NPB 1002

Perform the following operationevery timeyou come to class to ensure that the H-ITT remote is set to the proper frequency:(Alternatively, Softclick is a way of using your phone rather than the remote. It is allowed, but not recommended. If you use "Softclick" to enter your responses, the two word random code you will need will be provided on the screen projecting the HITT responses.)

- Press & Hold "down arrow" until light turns red.
- Press "0" until light flashes green
- To link to the room receiver for NPB1002: Press "9" until light flashes green
- Press "down arrow" until light blinks green.
- Done!

Clicker questions are worth 2 points for a correct answer, 1 point for incorrect. The total number of points for the semester will be large, maybe 100 or more, then we scale that to 20% of the grade. Clearly half of this component of the grade is for just being there!

Grading policy.Maximum total possible 100 points The 100% consists of 5 components adding to 100 points.

In-class quizzes (multiple-choice using the HITT clicker system) 20 points

Exam 1: 18 points

Exam 2: 18 points

Exam 3: 18 points

Exam 3(final): 26 points

Tests:The tests are generally "fill-in-the-blank" rather than multiple choice. They are closed book and closed note, but essential formulae are given. Most answers are considered "right" or "wrong". Any calculators (without internet access!) are allowed on all the exams, but most questions will not need calculators.

The following is the guaranteed grading scale:

76% A

72% A-

68% B+

64% B

60% B-

55% C+

50% C

45% C-

40% D+

35% D

Please note that the grading scale, at first sight, may seem "generous". This is because the scores on tests that are "fill-in-the-blank" are typically lower than for multiple-choice tests. All grades and other course-specific material can be accessed through e-learning Canvashere.Scores on each test will appear in the Canvas gradebook ("grades" on the LHS), as will HITT scores periodically. Students can therefore calculate, at any time, their projected grade. In general there will be a small number of clicker questions each Monday and Friday class, and several each Wednesday. Please don't ask for individual extra credit - it is against the rules for good reasons!

Philosophy of the course:This course is designed for so that it can be taken by students who do not have a background in physics. However, it is not a course about the philosophy or history of physics (though both will be touched on), but a genuine science course. Therefore some mathematics (at the level of the SAT quantitive) is necessary. It should be taken by people who want a one semester overview of physics. It counts as a Physical Science for "P" credits. It may be useful for students, especially those who have not taken a physics course in high school, as preparation for Physics I courses such as PHY 2053 and PHY 2048.

Hints on how to do well:

Listen to every lecture. The course is based on the lectures The syllabus is defined by what is covered in lectures, and you will not be tested on material not presented, whereas the books also cover other material which you are NOT expected to know.

Because this course covers all of physics in one semester, we move fast. If you sleep through a lecture or two, you will miss material. Make-ups will be considered on a case-by-case basis. Please contact the instructor.

Students requesting classroom accommodation must first register with the Dean of Students Office. The Dean of Students Office will provide documentation to the student who must then provide this documentation to the Instructor when requesting accomodation. However, it is impractical to ask for accommodations for in-class clicker questions. Remember that there is a online version of the course which might be a better option if this is a concern.

Information on current UF grading policies for assigning grade points can be found in the undergraduate catalog https://catalog.ufl.edu/ugrad/current/regulations/info/grades.aspxHere is the relevant "area objective":

This is a University of Florida General Education course, for which credit may be obtained in the "P" (Physical Sciences) category.

The physical and biological sciences provide instruction in the basic concepts, theories and terms of the scientific method. Courses focus on major scientific developments and their impacts on society, science and the environment, and the relevant processes that govern biological and/or physical systems. You will formulate empirically-testable hypotheses derived from the study of physical processes and living things, apply logical reasoning skills through scientific criticism and argument, and apply techniques of discovery and critical thinking to evaluate the outcomes of experiments.

To achieve these goals, students will be expected to:

a) analyze particular physical situations, and thus identify the fundamental principles pertinent to the situations

b) apply principles to particular situations

c) solve any equations arising from the application of identified principles of physics

d) communicate results unambiguouslyThis course will also assess Student Learning Outcomes which can be defined as:

Student Learning Outcomes

Student Learning Outcomes: Content and Skills

Content: Students demonstrate competence in the terminology, concepts, theories and methodologies used within the discipline.

Communication: Students communicate knowledge, ideas and reasoning clearly effectively in written and oral forms appropriate to the discipline.

Critical Thinking: Students analyze information carefully and logically from multiple perspectives, using discipline-specific methods, and develop reasoned solutions to problems.

The Student Learning Outcomes will be assessed through many in-class quizzes, 3 in-class closed-book exams, and the final exam. Quiz and exam questions will cover all subjects listed in the syllabus. Typical questions will require students to complete successfully all four steps outlined in the area objectives above. Obtaining the correct result to the question posed in the form requested in the question will be taken as evidence that all four of the steps have been correctly and successfully completed. In some questions students will be expected to choose between a series of possible explanations of physical outcomes; such explanations may be presented as graphs, numerically or in words. Although knowledge of the fundamental principles of physics is necessary for success in the course, the stress is on understanding how to apply the principles to a variety of situations; rote memorization is minimal.

Students are expected to provide feedback on the quality of instruction in this course. These evaluations are conducted online at https://evaluations.ufl.edu. Evaluations will be open towards the end of the semester and students will be informed at that time. Summary results of these assessments are available to students at https://evaluations.ufl.edu/results

Students requesting special accommodations must first register with the Dean of Students Office. The Dean of Students Office will provide documentaion to the student who must then provide this documentation to the instructor when requesting accomodation.

UF students are bound by The Honor Pledge which states, "We, the members of the University of Florida community, pledge to hold ourselves and our peers to the highest standards of honor and integrity by abiding by the Honor Code. On all work submitted for credit by students at the University of Florida, the following pledge is either required or implied: "On my honor, I have neither given nor received unauthorized aid in doing this assignment" The Honor Code (http://www.dso.ufl.edu/sccr/process/student-conduct-honor-code) specifies a number of behaviors that are in violation of this code and the possible sanctions. Furthermore, you are obligated to report any condition that facilitates academic misconduct to appropriate personnel. If you have any questions or concerns, please consult with the instructor or TAs in this class.
