General
- Welcome to PHYS 221, the introductory calculus-based physics course for majors in physical sciences, engineering, pre-medicine, and mathematics. You will learn mechanics, how things move, and why they move the way they do. I hope that you find it interesting and enjoyable. Have a great quarter!
- Concurrent enrollment in Phys& 231 is required.
- Completing MATH 151 (Calculus I) with 2.0 or better grade point is a prerequisite for this class.
- You must take this course with a decimal grading.
- Never let anything go by if you do not understand. Generally, ask questions immediately. If it is inconvenient to interrupt, make a quick note to yourself and inquire later.
- It is expected that you will attend all lectures and seminars. Class participation is also expected.
- Please turn off cell phones and pagers during class. Students exhibiting disruptive behaviors will be asked to leave the classroom for that day. Should this occur more than once with a particular student, administrative action might be taken.

Grading Policy
- The points earned in various components will be weighted according to the following percentages:
Midterm 25% Final exam 40% Labs 20% Homework 10% Quizzes 5%
- The final course grade is based on the percentage of the possible points with the above weighting.
- The grade point is assigned based on the following formula:
- grade point = weighted percentage x 0.065 - 2
- If the above formula yields grade point greater than 4.0 (greater than ~92%), you will receive 4.0.
- If the above formula yields grade point less than 0.7 (less than ~40%), you will receive 0.0.
Make-up Policy
- If you are absent due to the result of an unavoidable serious accident, a death in the family, or a serious illness, etc, please contact me as soon as possible so arrangements may be made for missed work.
- These exceptional circumstances must be verified by an appropriate third party, e.g., a police report, a funeral notice, or a letter from the student’s doctor stating the patient’s inability to attend.
- If you provide sufficient evidence for your exceptional circumstances in a timely manner, the following can be applied.
- Quizzes may not be made up, but may be dropped.
- Midterm exam cannot be made up, but may be dropped.
- Extention to homework may be given if necessary.
Exams
- Midterm exam will be given on October 28th.
- Final exam will be given on December 9th from 11:30am to 1:20pm.
- Both exams are closed-book. But equation sheets will be provided.
- Bring a scantron sheet for each exam.
- Calculators are permitted, but text storage and graphics functionality must not be used. Cell phones, computers or any other devices that enable you to communicate with others are not permitted.
- You will be shown a statement of what is and is not allowed on exams, and you will be asked to sign an agreement to abide by these principles. Basically the agreement is that you shall not cheat on exams.
- Exam Re-grades: 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 use this form and attach it to the front page of the exam explaining the possible error in the grading and return it to me. Do not make *any* changes or marks on the other pages of the examination. Each examination may be scanned or photocopied. 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.
- All re-graded scores are final, unchangeable, and not negotiable.
Seminars
- We will meet for seminar every Wednesday.
- You will work on problems in a group of 3 or 4 students, focusing on difficult topics and exam material.
- The seminar work is not graded.
Homework
- Homework will be assigned and collected weekly through the WebAssign system.
- "Class Key" for WebAssign log-in is shoreline 1212 2360.
- Instructions on WebAssign is found here.
- The homework will be due at 9:00pm each Monday.
- Each homework assignment consists of 10 mandatory point-bearing questions and 10 optional practice questions.
Quizzes
- I will give you pop quizzes at random times during lectures. The quizzes are on the material that I just covered in the lecture.
- For each quiz, you will receive 2 point for attempting, and another point if your answer is correct.
- You are encouraged to help each other. However, just telling answers to your classmates without giving explanations is not allowed.
- All the quizzes given to date are posted on BlackBoard under Course Documents.
Getting Help
- You are encouraged to post questions and answer questions on the disscussion board.
- You are strongly encouraged to visit me regularly during office hours (W 1:30pm to 2:30pm, Th 1:30pm to 3:30pm, and F 11:00am to 11:20am).
- You can also visit me by appointment.
- I will attempt to answer questions by email in a timely manner.
Academic Integrity
- You are not allowed to present something that you did not do as your own work. You are not allowed to help someone else to cheat.
- If students are suspected of cheating on an exam, they will be asked to discuss the situation with me. If they failed to explain the situation, they will receive a zero for the exam.
- If cheating has occurred, the student(s) will receive a zero for the exam.
- If a student cheats twice in one quarter, they will receive a zero for the course.
Inclement Weather
- In the case of extremely inclement weather, students should check the school’s website for closure information.
- You may also get school closure information from local radio and television stations, but be sure to remember that SCC is NOT a part of the Shoreline public school district.
- Every attempt will be made to keep campus roads and walkways open, and students can expect that classes will start at their scheduled start times when/if the school does open.
- If school is closed because of snow or another emergency, we will pick up where we left off when class resumes.
- For more information, please refer to this website.
Students with disabilities
- Students with physical and/or learning disabilities need to be registered with Service for Students with Disabilities. For more details please refer to this website.
