You should expect to work several days of the week, though you are always welcome to work ahead (or negotiate alternate due days). The typical weekly schedule will be as follows:
Monday lecture (8:30-10:20 am in building 8, room 219): lecture, group work, quiz on previous week's topics
Monday homework: video lectures, memorization activity
Tuesday homework: online homework
Wednesday lecture (8:30-10:20 am in building 8, room 219): lecture, group work
Wednesday homework: online homework
Thursday homework: written homework, memorization activity
Lectures will be a mix of the following:
Traditional lecturing (with example problems)
Conceptual questions answered as individuals ("clicker"-type questions) with a bit of discussion with others as needed
Group problem-solving on whiteboards
While I normally expect you to pay attention and be on task during lecture, I understand that there are legitimate reasons to briefly leave the room, use your phone, or have off-topic conversations with other students. You are an adult and you get to make your own decisions about such things. But please limit these activities and avoid disrupting the class.
Homework is due at 11:55 pm on the day listed.
Each week will cover approximately one chapter from the text. See Canvas for more details.
Week 1 (9/29-10/2): math, science, units
Week 2 (10/6-10/9): Newton's laws (conceptual)
Week 3 (10/13-10/16): one-dimensional kinematics
Week 4 (10/20-10/23): two-dimensional kinematics
Week 5 (10/27-10/30): applications of Newton's laws
Week 6 (11/3-11/6): circular motion, orbits, and gravity
Week 7 (11/10, 11/12, 11/13): energy and work
Week 8 (11/17-11/20): energy and work, impulse and momentum
Week 9 (11/24-11/26): impulse and momentum
Week 10 (12/1-12/4): rotation
Comprehensive Final Exam (Monday, 12/8, 8-9:50 am)
You will not earn any points for some of the assigned work when it is impossible to track (reading the text).
You will earn some points simply for making a good effort. These activities (homework, group work, watching videos, memorization activity) are designed to be part of the learning process, not assessments. Do your best, but don’t worry about making some mistakes.
You will earn points on some activities only to the extent that your work is thorough, concise, and correct. The quizzes and the final exam are designed as both learning opportunities and assessments. So you should be concerned about being as complete and correct as possible on these.
All work in this class is open-book and open-note unless otherwise specified.
I cannot guarantee a particular grade as it is ultimately based on performance. But I can honestly say that almost every student I have had in decades of teaching who completed all of the work earned at least a B.
A = 90%–100%
B = 80%–89.9%
C = 70%–79.9%
D = 60%–69.9%
F = 0%–59.9%
Percentages may be rounded up at the discretion of the instructor.
Note: all points listed below are approximate. I might make subtle adjustments during the term.
Homework and group work: 130 points
Videos: 30 points
Memorization: 10 points
Group work: 30 points
Online homework: 30 points
Written homework: 30 points
Tests: 170 points
Chapter quizzes: 90 points
Final exam: 80 points
Videos: You will earn one point for answering all of the questions during the lecture videos. The website will not give you full credit if you miss some questions, but I will override your score. Sometimes the software glitches and doesn’t give you credit at all; if so, then contact me on Canvas to fix it.
Memorization: Physics has some symbols, terms, units, and formulas that are important to memorize so that you can focus your efforts on problem-solving instead. You will be provided with online flashcards. You can use these or make your own physical copies. You will earn one point each week for doing so twice per week.
Group Work: You will practice problems on whiteboards during the lectures, earning around 3 points per week for a reasonable effort and adherence to guidelines. Good group work includes the following:
Make and correct mistakes. You will not be punished for making mistakes, though you will be expected to correct them when challenged by me.
Build consensus (discuss your work), share the workload, and change roles. Use different colored pens to demonstrate this.
Show your work/reasoning (see below) even if you think the answer is obvious or you can do the math in your head. Getting correct answers is not sufficient.
Work on one problem (or part of a problem) at a time instead of working in parallel.
Don't erase anything until it has been checked by me and you have photographed your work for future reference. You will submit your work for credit with your written homework.
Online Homework: You will complete online homework for approximately 3 points each week. Points shown while you are doing online homework do not correspond with points for the class; they are there simply to show you how you are doing. Use Canvas or office hours for help (and to help other students).
Written Homework: You will complete, photograph (if not typed), and upload written homework for approximately 3 points per week. Written homework will sometimes be challenging and may require the use of ideas from multiple chapters of the text. Use Canvas or office hours for help (and to help other students). I will post solutions to written homework after the due dates.
Chapter Quizzes and Final Exam: You will demonstrate your learning on open-book (hard copy only) and open-note (print these out in advance) quizzes (30 minute time limit, 10 points each) and the final exam (2 hour time limit, 80 points). Questions will be mostly "essay" with occasional multiple choice. You will be expected to use general physical principles to solve novel problems; do not expect simple repetition of problems you have already done as homework with the numbers changed. You must show your work (see below).
You will be graded based on showing your work on group work, written homework, chapter quizzes, and the final exam. This will normally include the following:
Equations used (including names of equations if they exist)
A short, verbal justification for each of the equations used (why they are true)
Symbolic solution for the variable of interest (you do not need to show all of your algebra). It should be concise and simple (as few division signs and appearances of each variable as possible). Symbolic solution means that you don’t plug in any numbers in the middle of your algebra other than zeros (which simplify the equation).
Numbers plugged into the symbolic solution
Answer with units
Reflect on reasonableness of answer, if possible
You will lose a point on your group work and written homework if work is consistently missing. A correct answer with missing or incorrect work (or an incorrect answer with correct work) on a quiz or exam will result in half credit for the problem.
Late Policy: Late work and make-ups will not generally be allowed without prior arrangements. In advance, you may negotiate alternate due dates. Do not be afraid to ask; the answer is almost always “yes.” When negotiating alternate due dates, you do not need to divulge personal information; focus on what you need instead of why. There are a few exceptions to this policy:
During the first week, more flexibility is called for as you get oriented to the class. Just make sure that you get everything done by Friday so that you don’t get dropped from the class.
Technical or last minute personal issues might cause you to turn in your work a few minutes late without negotiations in advance. Don’t panic or abandon the work; you will not be blocked by Canvas. Just turn in the work as soon as you can and I will almost certainly grade it without penalty if you aren’t making it a habit. But be sure to communicate with me if it will be more than a few hours late. And be sure to negotiate in advance whenever possible.
You may occasionally award yourself an extension of one day on online homework or a video lecture.
If you post a question on the homework and it is not answered by the time it is due, then you may have a one day extension.
Incomplete Policy: A grade of incomplete (I) may be negotiated when a student with passing work needs additional time to complete the course. An incomplete will not be granted as a substitute for a failing grade (F).
No-Show Drop Procedure: You are required to complete nearly all of the work assigned during the first week. Failure to do so may result in a “no-show drop” at the discretion of the instructor.
Grade Appeals: You have one week from the time anything is graded to appeal its score in writing. Failure to do so constitutes acceptance of the grade. Please (respectfully) appeal grades that you either don’t understand or think are incorrect. It can be an opportunity for learning and I do make mistakes.
File Formats: Lab reports, written homework, and group work must be submitted as a single pdf only. Please always name your files with your name and the name of the assignment included. Always submit images right side up; rotate them if needed. Do not ever take photos of your monitor; take screenshots instead. Work that is submitted in an unapproved format may be returned for resubmission or given a zero.
You may earn up to 10 points with extra projects. Please note the following:
Extra projects will not generally be an efficient use of your time in terms of points earned per hour of work. You are unlikely to receive any points for an extra project with substantive mistakes. With the exception of reporting correctable errors, I will assess points as I see fit; do not ask me what something will be worth in advance.
These may not be completed during week 10 or finals week, so they should not be seen as ways to bump up a borderline letter grade at the last minute.
The following are some suggestions for extra projects:
Report correctable errors (spelling, grammar, physics, etc.) in the websites or documents for this course. Post the error to Canvas and earn a point. Repeated errors do not earn additional points. Note that I prefer to put commas and periods outside quotation marks when they aren't actually part of the quote (the English rather than the American convention). This is a deliberate choice and not an error.
Perform an additional lab of your own design. You may work in a team. Write it in the normal format, but include a procedure as part of your raw data. You must consult with me as you develop ideas.
Write a computer program. The program should solve a physics problem you cannot solve analytically, solve a wide variety of problems, or have an instructive animation. You must consult with me as you develop ideas.
Attend a Chemeketa planetarium show. Submit a paragraph of notes to me.
Watch some videos on physics or astronomy and submit a paragraph of notes for each one. Veritasium has some excellent physics videos (please stick to the physics playlist). The astronomy videos from Kurzgesagt are good (select ones that interest you from the list). Feel free to suggest other videos.
Join the search for gravitational waves by using your idle computer to analyze data from pulsars. You can give Chemeketa some fame and earn yourself some extra credit. Please follow these instructions:
Go to the BOINC website Einstein@Home. Follow the directions for installing the BOINC software and joining Einstein@Home. Use a descriptive username such as your first name and last initial.
Install the software on all computers you control. The software can be configured to run as a screensaver so it will only use your computers when they are idle, or you can choose to leave it on all the time in the background. Adjust how often and how much of the CPU is used.
With laptops, I recommend that you avoid running at 100% of CPU time as they tend to overheat. With any computer, if you choose to leave it on all the time in the background, then it will slow down your computer.
You will earn points based on the amount of data crunched by your computers by the end of the term. Just think, you can earn points while you sleep! Leave your computers on all the time. It will only cost you a few dollars a month in electricity for each computer. Better yet, enlist computers of your friends and family. There is a bit of a time lag (about a week) between when you crunch the data and get credit for it on the team page.
Near the end of the term, send me a screen shot showing the amount of "credit" you have earned.
Please don't ask me for computer technical support. You must figure out how to do this on your own, though you are welcome to discuss this with other students.
