${\tb WEB SITE:}$ Course information is available at http://feynman.stcloudstate.edu/haglin/235

${\tb TEXT:}$ The required text for the course is ``University Physics'', 11th Edition, by Young & Freedman, Pearson Addison Wesley (2004).

${\tb PREREQUISITE:}$ Grades of C or better in Math 221 and Phys 234; Co-requisite: Math 222.

${\tb Course Description:}$ Physics 235 is the second in a two-semester sequence of calculus-based introductory physics. Students continue to develop their scientific problem solving skills and critical thinking through study of waves, sound phenomena, electricity and magnetism, and optics.

${\tb Problem Sets:}$ Physics cannot be learned without actively ${\ti doing physics}$ . Thinking through the assigned problems represents exercise for building strong computational abilities and confidence. You are encouraged to solve as many end-of-chapter problems as you can. Written solutions to assigned problems are due the beginnings of the class periods identified by the instructor throughout the semester. No late assignments will be accepted without prior arrangement. Full credit on the problem sets requires not only the correct answers, but also a documented logical progression of steps taken. ${\tb You must show your work!}$

${\tb Group Learning:}$ You are encouraged to work together if you would like on homework problems and on laboratory activities. However, each student must prepare her or his own papers. Furthermore, during the examinations absolutely no assistance from others is allowed.

${\tb Examinations:}$ There will be three examinations during the semester. An equation sheet will be supplied for each exam.

${\tb Final Examination:}$ The final examination will be comprehensive. As with the other exams, an equation sheet will be supplied.

${\tb Grading:}$ Your grade in this course will be determined by your performance on the three examinations plus the final examination, by your diligence and success in working the assigned problems, and by your performance on laboratory reports. The weight of each component in determining the final grade is shown below:

Problem Sets             15%

Labs             20%

(3) Exams             45%         (15% each)

Final Exam             20%

The overall grading scale will use the so-called shaded grading (the pluses and minuses) as indicated below.

A+             98%

A             92%

A-             90%

B+             88%

B             82%

B-             80%

C+             78%

C             72%

C-             70%

D+             68%

D             62%

D-             60%

F          60%

The instructor reserves the right to adjust these numbers downward at the end of the semester.

${\tb Assistance:}$ If you have difficulty with topics covered in lecture, with problems from the homework, or other difficulties, please feel free to visit my office during office hours. Tutoring is also available in WSB 335 during scheduled times posted outside the room.

The labs are ${\tb very}$ important as they provide hands-on experience to help you understand the physics concepts. You may not miss more than two labs if you wish to have a passing grade for the laboratory component to the overall course grade. ${\tb Each person must complete a report for each week's activity, due at the next laboratory meeting}$ .

Student Learning Outcomes

After successfully completing this course students will be expected above all else to ${\tb solve problems related to}$ the following skill set. That is, students will be expected to ...
