PHYS 115: General Physics

PHYS 115: General Physics

Welcome to PHYS 115, the second of the algebra based introductory physics sequence. You should find this course challenging and stimulating, and I hope that you also find it interesting and enjoyable. 

 

Focus of Phys 115 

This course will focus on analysis of the physical world using laws and principle of physics such as the laws of thermodynamics and the laws of electricity and magnetism. Topics covered will include fluid mechanics, thermal physics, and electromagnetism. Lectures will focus on the conceptual understanding of these topics and quantitative problem solving skills.

 

Course objectives

Upon successful completion of this course, students will be able to:

1.   Develop algebra-based models to describe the physical world.

2.   Apply physical laws to understand physical phenomena.

3.   Utilize and apply the laws of physics pertaining to:

      a. static and dynamic fluid mechanics
      b. temperature and heat
      c. phases of matter
      d. thermal processes and entropy
      e. electric and magnetic field and force
      f. electric potential and potential energy
      g. electric current and circuits

Textbook

 

Trailer Videos

  • OpenStax provides some trailer videos that are available here.
  • Please check the schedule, and watch the videos that are associated to lectures before coming to the class.

 

Schedule

We will follow the schedule in the syllabus as closely as possible, and we will announce changes as necessary. 

 

Exams

  • There will be two midterm exams and a final exam. All exams are closed-book. However, I will provide equation sheets.
  • Midterm exams have multiple-choice questions and long answer questions. Final exam has all multiple-choice questions. Therefore, you need a bubble sheet for each exam.
  • Calculators are permitted. However, the use of the text-storage capability is not permitted. Cell phones, radios, laptop computers etc that allow you to communicate with others are not permitted. 
  • Note that there will be no make-up exams in PHYS 115. Students with outside professional, service, or career commitments (i.e. military service, ROTC, professional conference presentation, NCAA sports, etc.) conflicting exactly with the exam dates must contact the instructor early in the quarter to establish alternate examination procedures. Students who miss an exam without making prior arrangements with the lecture instructor will drop that exam score. Students who miss an exam due to emergency need to contact the instructor as soon as possible.
  • If you believe that the points on the examination were incorrectly totaled, or if there is a gross error in the grading, you may return an exam for regrading. To do so, you must resubmit the examination no later than at the beginning of the lecture following the one in which the exams are returned. You must attach a regrade request formDo not make *any* changes or marks on the pages of the examination. You should be aware that any request for a regrade may result in a regrading of the entire exam. Therefore your total score may increase or decrease.

 

Homework

  • Homework will be assigned and collected weekly through the ExpertTA system.
    • Student Class Code: UST49WA-129FFB-1CM
    • Use your UW email address to register (@uw.edu).
    • There is a two-week grace period. After that you will need to purchase the access at $27.50.
    • You can follow the instruction on how to register for ExpertTA.
    • If you need a technical support from ExpertTA, contact them: main@theexpertta.com or 24x7 toll-free 877-572-0734.
  • The homework will be due at 11:00pm each Tuesday (except for homework 2 and 8). The first homework will be due April 12th. 
  • You can attempt up to 5 times for each question without penalty.
  • You can earn up to 50% of points for late homework.
  • If you earn 90% of the total possible points at the end of the quarter, you will get a full credit. 

 

In-Class Quizzes

  • I will ask a few questions per lecture where you can respond using an TX3200 RF transceiver (Clicker), which are available from the University Bookstore.
  • You need to register your clicker here.
  • For each question, I first ask you to answer on your own. I will then look at the answer distribution. If less than 80% of the students chose the correct answer, I will ask you to discuss with your peers and answer the same question again.
  • For each in-class quiz, you will receive 4/5 of credit for attempting to answer, and the other 1/5 for having the correct answer. If a question is asked twice, only the 2nd attempt counts towards your grade. 
  • You will get a full credit for the in-class quiz section of the grade if you earn more than 80%.
  • You are encouraged to discuss your answers with your classmates.
  • If your clicker is not working during an in-class quiz, check that the channel has not been reset by setting the correct channel again.
  • If you forget to bring your clicker to class or your clicker is not working, you do not get a credit.
  • Your clicker's channel should be configured to channel 01.
    • If you have an older model, instructions to configure your clicker can be found in this link.
    • For the newer iCue Pro model, please see the following:
    1. Use the MNU key to display the RF channel change mode
    2. Set to RF channel 1
    3. Press the SEND key
    4. The LED will flash green

 

Grading Policy

The final course grade is based on one of the following grade weightings. Your final grade will be assigned based on the option that gives you the higher grade. Therefore, if you miss a midterm for example, your grade will be determined using option 2.

  • Option 1:
2 midterm exams 46%
Final exam 23%
Homework 25%
In-class quizzes 6%

 

  • Option 2:
Midterm exam (better 1 of 2) 23%
Final exam 46%
Homework 25%
In-class quizzes 6%

 

  • Your responsibility: Check your grades on ExpertTA for homework and Catalyst (Section A or Section B) for the rest every week or two and report any problems to me immediately. Exam grades should be recorded for your review within one week from the date of completion of your work. ExpertTA homework grades should be recorded immediately after submission. Grading problems that are reported in a timely fashion will be investigated and, if action is warranted, corrected. I may choose to ignore grading complaints that are not reported in a timely fashion.

 

Study Center

  • Students are encouraged to gather and work cooperatively in small groups in the Physics Study Center
  • The Physics Study Center is located in room AM018 of Physics and Astronomy building. To reach it, go down the stairs that circle behind the Foucault pendulum and proceed toward the end of the hall.
  • Teaching assistants will be available for consultation during many portions of the day if your study group needs assistance, but staffing levels will not support much individual attention. The Study Center is staffed from approximately 9:30am to 5:00pm on weekdays. A schedule of who is staffing the physics study center can be found here: Study Center Hours.

 

Discussion Forum

There is a discussion button to the left. You are encouraged to to ask your fellow students for help with homework, or to organize study groups, etc.

Phys 118 Labs

Taking a laboratory course, Phys 118, concurrently is strongly recommended.

  • Professor Robert Van Dyck (vandyck@phys.washington.edu) is in charge of Phys 118.
  • More information on the laboratory section is given here.
  • Many of the labs finish late at night, so I encourage all of you to look at the following useful Safety links.
