PHYS 223 Lab Information
Office:
104 Lewis Hall aka "tutoring room" or "Physics Learning Center".
Office Hours:
Thursdays 9-11 AM. Being a graduate student, i've some time constraints. So, please try to stick to these office hours. In case, these hours doesn't work out with you, appointments can be scheduled, but should atleast be a day before the Lab meets. Last minute requests will not be entertained. Please, note that Mondays are blackout.
Some questions, doubts can be addressed via

PHYS 223 LAB: Fall 2009
Notices
Oct 20, 2009:
As was announced (students notes) in last lab, this week we will do Experiment 9: Conservation of energy and Linear momentum.
Oct 7, 2009:
Full Lab report (format on page - 4 of Lab Manual) is required for Experitment 6: Newton's Second Law:
- Advice for writing full lab report is here, pay attention to sources of errors and uncertainity.
- Full lab reports requires lot more effort on your part, so start early.
- Get your draft report checked by me or Ms. Beth.
- I do not have time on Mondays, so please start early.
Notes for Lab
Follow the link on accuracy vs precision.
- Accuracy: measurement match exact (or accepted) value.
- Precision: ability to reproduce a measurement consistently or the number of significant digits to which a value can be reliably measured.
For example, for acceleration due to gravity near earth, the value g = 9.7345 m/s2 is more precise compared to value g = 9.81 m/s2, since it has more number of sig. figs. Where as the later is more accurate measurement since it is closer to the accepted value of g = 9.80 m/s2
Advise on Grades
Grades are effected roughly by 3 factors (but not limited to):
Quiz: focuses on current experiment. Studying Pre-Lab thorougly and whatever physics problem being considered in the experiment is a good start. By physics problem, I mean, for example, experiment 5 on projectile motion, involves projectile being shot at angle 0o and angle >00 and similarly, experiment 6 is related to modified Atwood machine. So, study the related problem well and try to understand the concepts involved. It may be a good idea to start by looking up a solved example in the textbook and/or stop by Room 104 (Tutoring room).
Exams: Similar to quizes but little more challenging.
Reports: Its couple of hour work and you've whole week at your disposal. Please don't loose point on this. Stick to the format (as well as grading key) given in Lab manual on page 4 and 5.
Useful Links
Physics for K-12 Has some good physics collection (a little bit advanced than pre-lab level). You can choose a topic from "Table of contents" given on left hand side. For ex,
