El Camino College     Physics 1B      Fluids, Thermodynamics, and Waves        Fall 2017

 

Section 1377  meets Tuesdays 6:00-9:10 and Thursdays 6:00-8:05 in Physics 109.       

 

Instructor:  Perry Hacking; Office Planetarium; (310) 660-3593 (x3245); Office Hours:  Tuesdays - Thursdays 3:30-4:00, Wednesdays 5:00-7:00.    Email:  phacking@elcamino.edu

 

Text:  Sear's & Zemansky's University Physics by Young and Freedman, 14th edition;  and the ECC Physics 1B lab manual.

 

Materials: 1.  A BOUND lab notebook.  A composition notebook is okay, but one with graph paper is better. 2.  Record your notes and store all of your returned papers in a 3-ring loose-leaf notebook.  Do not keep notes in a spiral bound notebook.  3. Colored pencils, clear plastic ruler, a small 30-60-90 plastic triangle, a circle drawing template with sizes from tiny to about 2-inches in diameter, and a French curve.  Store these in a plastic three-hole pouch in your loose-leaf notebook. 

 

Prerequisites: Physics 1A with a grade of C or better, Math 191 with a grade of C or better or taken concurrently. 

 

Free Tutor:  See MESA Center  for tutor days and times, or see the free tutor in the Learning Resources Center in the Library.

 

Exams:  There will be three 50-point exams and a 100 point comprehensive final exam. The exam questions will be similar to the homework questions.

 

Homework:  There will be homework assignments for every chapter of the book that we cover.  Homework will be worth 100 points total.  No late homework will be accepted.  Note: homework is due AT THE BEGINNING OF CLASS, before I finish calling the roll.  It is futile to come to class late because you were trying to finish your homework.  It is also futile to expect to pass the course if you don't do the homework or rely heavily on others to help you along.  If you cannot do the homework or don't understand how to solve the problems, you will not be able to answer the test questions.  Reminder:  by now you should be well aware that memorization will get you nowhere in physics (with the small exception of memorizing a few important constants or units).  Understanding is key.  Seek help as you need it.  Physics punishes procrastinators or last minute "cramming" mercilessly. 

 

Labs:  We are currently scheduled to perform 8 labs.  Your total lab work will be worth 150 points.  Your lab notebook will be graded as part of the total lab grade.  Some exam questions will be "real world" problems very similar to the labs in which you will be required to perform similar measurements and/or observe and explain real phenomena.  Do not treat the lab portion of this course as somehow separate from the rest.  Exams will contain lab elements (not just word problems).  Suggestion: try to perform as much of each lab yourself as possible so you will know what to do if you have to handle the same equipment during an exam. 

 

Grading:  I will total all of your points at the end of the semester to determine your grade.  The grade scale is as follows:

 

           each exam          for the course

            

           90 - 100   A       450 - 500  A

           80 - 89    B         400 - 449   B

           65 - 79    C         325 - 399   C

           50 - 64    D         250 - 324   D

 

Students who withdraw after September 1st will have a record of it on their transcript.  Those that withdraw after November 17th will receive a letter grade based on the entire semester's requirements. 

 

Preparation:  Make certain that you are ahead in your reading, and current on your homework!  Homework will be due almost every time we meet (including labs).  You will be able to find every topic that we cover in your text and ECC physics 1B manual.  

 

Course Objectives  and Student Learning Outcome (SLO):  In general, the objectives of this course are to learn the physics of static and moving particles, fluids, or heat and to learn to correctly analyze physical problems that deal with those subjects.  The official course objectives and SLO can be found at: Physics 1B Course Objectives.

 

About this course: The best way to learn physics is by seeing as many different ways that it can be applied in the real world.  That is what we are going to do.  Most of the examples that we will use will be simple ones that isolate the concepts that we will be learning about.  Of course the real world is more complicated and real world problems often involve many different laws or concepts.  The process is the same, however - try to identify the concepts at work in the problem.   Before we can tackle the real world, we will start in this course to understand and solve problems that usually involve only one or two concepts, and rarely three or more.  Before we are done, we will routinely solve problems that involve multiple concepts.

 

Advice: This is an important course for you.  I will assume that it shares top priority with your math course in your schedule. If you do not give this course top priority, future physics and related courses will suffer.  The Physics 1 series is often thought of as the cornerstone of your college education in any technical field.  Make it a strong cornerstone.  Even though the homework grade is only worth 20% of the total points, it is probably the most important aspect of this course.  Practice, practice, practice.  That will be our motto.  Homework will be our tool.  We will practice a great deal in class also.   You can be assured that I will treat this course as your most important one also.  I pledge to do my best to make this wonderful course as understandable and interesting as I possibly can.  I hope to fill you with the wonder that I have for our physical universe around us. 

 

However, when I stumble and you become confused, it is YOUR responsibility to stop me and ask for clarification or a different explanation or illustration.  Silence on your part translates into an assumption on my part that you understand.  ASK QUESTIONS.  This is not a passive class where you just show up and take notes.  Expect me to ask you questions all period long.  Yes, you. 

 

Come to class with an active mind ready to learn every time that we meet.  Don't show up burned out and hungry.  This is not a painting class where you can relax and unwind.  I require your FULL attention and your mind at top speed.   I need fresh brains in my class!  Make sure that you have dinner before class.

 

Disabilities: If you have a documented disability and wish to discuss academic accommodations, please contact me as soon as possible

 

Preparation:  Here is what I suggest if you want to ensure that you are well-prepared for this course:

Prep 1.  Go to chapter 1 of the text and review everything about vectors described there, especially relative vectors, cross-products, and dot products.   You should be able to easily solve any of the problems at the end of the chapter. 

Prep 2.   Review energy and especially conservative forces.  Review sections 7.3, 7.4, and 7.5 of the text.  Solve question 871 in the Physics 1A lab manual in the energy section that involves graphing potentials.  It is quite lengthy, but not very difficult. 

Prep 3.  I suggest that you obtain the text and lab manual.  First review impulse and momentum and simple harmonic oscillators from Physics 1A.  Then read Chapter 12 in the text and F-1 in the Lab Manual to get an early start. This early start, done without the pressure of other courses and a tight schedule, will greatly increase the odds of you doing extremely well in the course.  If you know of any other people in this course, please pass along this suggestion.  I can be reached via email this summer if you have any questions (I may not respond right away, but I will respond).   If you really want to get a jump on the semester, here are our first homework assignments:
