Syllabus
Introduction :
The first of a two-semester series in general physics. The first semester covers the fields of mechanics, oscillations and waves, and thermodynamics. The aim of all your coursework, including homework, quizzes, lab, midterms, and final exam will be:
- Understanding of concepts: understanding the basic principles of mechanics, oscillations and waves and thermodynamics: This entails some knowledge of scientific facts such as Newton's Laws and other basic principles of physics. The main difficulty will be to get an understanding (through practice, more practice, and occasional lectures) how to usefully "invoke" the principles of physics to solve a specific problem.
- Problem solving: Once you have figured out what principle to use to solve a particular problem, the second step is to learn how to write down mathematical relations that are based on that principle and solve them with some calculus.

Grading
| Homework and quizzes | 25% |
| First Hour Exam | 15% |
| Second Hour Exam | 15% |
| Lab | 20% |
| Final Exam | 25% |
Homework
There will be weekly homework assignments using I-Lrn (see above).
Homework will be due Mondays before class (11am)(except: Mon 9/6 is a holiday,
so HW will be due Wed 9/8 at 11am).
Solutions to the homework will be posted on the web. Homework is extremely important as it will help you clarify your understanding of the material, point out areas of weakness and help you prepare for the exams. It is extremely difficult to do well in this course without carefully doing the
homework.
Quizzes
You will need to complete a short on-line quiz before each lecture (except the first lecture)
Mid Term Exams
There will be two 50 minute in class mid term exams: Wednesday, October 6 and Friday, November
5. These exams will have questions very similar to the homework and the quizzes. They each count 15% toward your course grade.
Discussion
The discussion is scheduled just prior to your lab session.
This is an opportunity to obtain clarification of the material presented in
class, in the text, or in the lab. Discussion sessions will give you a
"hands-on" introduction on how to solve problems. They are also
an opportunity to get help from the TA and from fellow
students.
Laboratory
The experiments in the laboratory are an integral part of this course.
Twelve experiments are scheduled. You cannot pass this course unless you do every experiment, and submit a report. You
need to start a draft of your lab report before you come to the lab. Bring
a page with your name, lab title, and a brief introduction (a few sentences in
one to two paragraphs) into what the purpose of the lab is in your own
words. Include in this pre-lab writeup at least one question for the TA
about the purpose of the lab, or questions about technical aspects of the
experiment and data analysis. 20% of the lab points will be subtracted
if you do not prepare the introduction and question for the TA prior to
lab. You will have to submit a lab report at the end of each lab
period. If you need more time and hand in a report after the end of
lab, 20% of the points for that lab will be subtracted.
The MONDAY lab and discussion section will already meet on Mon 8/30
since Mon 9/6 is a holiday. All other sections start Tue 9/7.

Week 14 (12/6 and 12/7) Make up week (only one experiment may be made up)
Tutoring
The Physics Department has a free tutoring service, the Slawsky Clinic,
run by a group of retired senior physicists. It is located in Room 1214 in the Physics building. The time reserved for PHYS141 is 10-11 and
12-1 Monday through Friday. However, you can usually get help at any time they are open, from10 AM until 3 PM.
