Physics 174: Physics Lab Introduction

Fall 2007, Prof. Arpita Upadhyaya

What the course is about:

Physics 174 is an introductory Physics Lab that meets for two hours each week in Room 3115 of the Physics Building. In this course you will be expected to master a few basic ideas and tools which you will need for later labs, including: understanding experimental errors, using computer spreadsheets for analyzing, plotting and fitting data, and working with simple electrical circuits and electrical measuring equipment.

Prerequisites: The only prerequisite or co-requisite for the course is Math 140. This course is intended for, but not limited to, students who are interested in majoring in Physics.

Texts: Physics 174 Lab Manual - Fall 2005 edition. Also you'll need a book on data analysis:  "A Practical Guide to Data Analysis for Physical Science Students" by Louis Lyons or Intro to Error Analysis by Taylor. Also recommended but not required is "EXCEL 97 at a Glance" by Microsoft.

 Arriving late to class:

Classes at Maryland begin right on the hour. It is important that you arrive on time to Physics 174 so that you can get instructions for the lab and have time to finish. If you arrive more than 10 minutes late, you may not be allowed into the lab and may have to make it up during another section. This is hard, because the sections are full, so, don't be late!

 

 Lab Makeup Time: If you miss your regular lab section, then you should make that lab up by going to another section that same week. If you have questions about the lab, the equipment, or the homework, you can also stop by during this time. If you cannot attend another section, contact your instructor ASAP and a time for a makeup lab will be arranged. In general, this should be done the same week as the lab is scheduled. Because the other sections are full, it is also very hard to do a make up, so do not miss your lab section.

Grading:

    50%     Lab Spreadsheets
    20%     Homework:    do the homework!!!
    15%    Test on spreadsheet, errors and measurements
    15%    Test on the oscilloscope and electrical circuits

Missing one Lab (and not making it up before the next lab) will cost one letter grade in your final grade. Missing one homework set will cost one-half of a letter grade in your final grade. No credit will be given for late homework unless you are seriously ill and provide a written note from your physician.

Homework is assigned at the end of each Lab. You will turn your homework electronically (we'll tell you how to do this at the first meeting) and you can turn it in anytime during the week, but by no later than 11:55 PM on the Monday before your next lab. Graded homework should be available a week after you turn it in.

General Comments on Homework: Finishing all the labs and homework sets is very important. Missing even one homework set will definitely hurt your grade. Just do it! Also, if you can't completely finish a homework set, turn in what you do have. When you are working on the homework sets, feel free to discuss among yourselves to try to figure out what is going on. However, do not use these discussions as an excuse to copy someone else's solution to the homework, or let someone else copy your solution. That is cheating and is strictly forbidden. It is also very self-defeating since another part of your grade will come from tests. The right way to discuss the homework is to first work through a problem on your own and arrive at a definite answer. With this preparation you can then discuss intelligently with your colleagues and see if you have missed something essential. Of course, you can always ask one of your instructors - that's what we are here for. One final thing, if you get something fundamental wrong on a homework set or the practical tests, you will probably be assigned extra problems to solve until you master the concept.
