Physics 275 - Spring 2005
Professors Rick Greene and Fred Wellstood

 

Physics 275 is the second course in the introductory Physics lab sequence PHYS 174-275-276. The course is intended for physics majors and also for science and engineering students who desire a more rigorous introduction to experimental science. Experiments are mainly chosen in the general area of mechanics. A major component of the course concerns understanding error analysis, both learning how to do it and appreciating what a useful tool it is. The Lab meets for four hours each week in Room 3203 of the Physics Building. Roughly three hours of this time will be spent working on the lab and one hour in discussions that occur during the lab.

 

Prerequisites: The prerequisites are Physics 174 and Physics 171 (or Physics 161).

Co-requisites: You must also be enrolled in Physics 272 in the same semester in order to get CORE lab science credit.

 * Office Hours: You can try stopping by our offices at any time, but if you can't find us, make an appointment by e-mail.

 

* Prerequisites: The prerequisites for the course are Physics 174 and Physics 171 (or  Physics161).

 

* Co-requisites: You must also be enrolled in Physics 272 in the same semester in order to get CORE lab                       science credit.

* Arriving late to class: Classes at Maryland begin right on the hour. It is important that you arrive on time 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 will have to make it up during another section.

 

* Making Up Missed Labs: You should make every effort not to miss your regularly scheduled lab. If you miss your regular lab section, you should make that lab up by going to another section that week or by scheduling a makeup lab with the TA before your next lab.

* Grading:      40%  Spreadsheet Lab Report

                        10%  Homework

                        20%  First Practical Exam

                        20%  Second Practical Exam

                        10%  Class Participation

 

            Missing one Lab (and not making it up ) 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. Final grades will be computed based upon the above weightings. Standard grading will be followed (A is 90-100, B is 80-90, etc.) unless the class's distribution of scores is unusual, in which case a standard curve will be used.

 

* Homework is assigned at the end of each Lab. You will turn your homework and any revisions to your lab by submitting an Excel spreadsheet file as an e-mail attachment to WebCT. You can turn in your report and homework anytime during the week, but by no later than 6 PM on the Sunday of the week in which you had the lab. Corrected homework should be available the following week.

 

* No credit will be given for late homework unless you are seriously ill and provide a written note from your physician.

 

* General Comments on the Lab report and Homework:

            Finishing all the lab reports and Homework sets is very important. If you can't completely finish a lab and homework set, it is still important to turn in what you do have. When you are working on your report or homework, feel free to discuss among yourselves to try to figure out what is going on. By all means get together in small groups and discuss. However, do not use these discussions as an excuse to copy someone else's report or homework solution, or let someone else copy yours. That is cheating and is strictly forbidden. It is also very self-defeating since the other part of your grade will come from tests. The right way to proceed is to first work through the report and problems by yourself 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. 

            One final thing, if you miss something fundamental in a lab or test, you will probably be assigned extra problems to solve until you master the concept.

 

* In case of Bad weather: Winter in the Washington Metro area can bring large snowstorms that make travel dangerous. Should this happen and the University is closed as a result during a scheduled lab, class will be cancelled, and we will most likely reschedule the lab for the following week. Closing is announced over local radio and TV as well as on the University’s homepage.

IMPORTANT NOTE: The Wednesday and Thursday sections will meet the very first week of classes. The Monday and Tuesday sections will meet starting on the following week and during their first meeting will complete Experiment 1 (which is just a short diagnostic of Physics 174 skills) and Experiment 2, which involves probability.  The idea is that in this way, we will have enough flexibility in the remainder of the semester to make-up a weeks worth of labs if school is shut for an extended time due to weather.
