Example-HW Format




1) Diagrams are not for show! Diagrams help you communicate what you know about the problem at hand. Draw them carefully. Label any parameters. Be neat and concise. Your diagram should be first.
2) You must explain some steps in your solution. I do not need you to explain algebraic manipulations. Why did you set something equal to zero? Why is the momentum before = zero. Why is it possible to set the KE before = PE after, etc.
Be concise. Do not be wordy. I do not need paragraphs of useless information.
3) Your solutions should start from the basic physics principle not from a derived equation. You can leave some algebra steps out but not the important ones. I do not need definitions for the Cons. Laws.
4) I suggest that you use a little color. Ex.1,2,3, more
5) Most important: Please keep all solutions to one page. If you can fit two solutions on one page. . .good.
Do not start a solution on one page and end on another page.
6) Work the problem out on scratch paper then transfer it to a clean piece of paper. Do this for all your problems.
This is a good way to clear up any mistakes and it will help you study for the test.
7) Solving problems from first principles is a process. You are trying to communicate your
understanding of the observed patterns in nature.
This is not hard. Read the book, follow the examples, and apply your skills.


On the Test, I will be giving points for your diagram,
points for your solution, and points for your reasoning and explanation.


Your First Personal Audio Recording

This is your first attempt at articulating who you are, what you know and what you have learned.
This recording will be put on the web next to your name in your group.
This assignment will allow you to compare your ability to articulate and compare yourself with your classmates.


What do I talk about?

Tell me about yourself. Why are you taking Physics 180A? What are your career plans? Why does Tony require us to explain the problems? Why do you need to draw diagrams? What do you expect from a Physics class? Try to be more interesting than you really are. . .ha!

Use an outline. Please do not read word-for-word. Try to sound like you are talking directly to someone.
Reminder, your recording should be at least 5 minutes long. Imagine that you are being asked questions
by an interviewer who wants to hire you or admit you to their Graduate School or Medical School!

Audios less than 5 minutes will get 50% of the points!

How do I record it?

How to record your voice. . .
A. You can use the PC's recorder. Instructions
B. There is a good voice recorder for Windows at Audio Recorder
C. How to use the sound recorder on Windows 2000, sound recorder on Windows XP, thanks Joe.
D. Save it in mp3 format, please!
E. Save your file:
audio file name:
Class_GroupName_LastName_assignment#
example: 180A_Daisies_DiMauro_r1

Make sure that you record it correctly. If I can't hear it, then you don't get credit.
Test it out, first. Make sure you are recording correctly.
It should not be larger than 12 megabytes!
Set your parameters in your recording software.


Where do I send my audio file?

Email your audio file to me.

email to: tdimauro@gmail.com
Please name your file correctly. I will take off 5 points for any wrongly named audio file!
