Course: Physics 122 primarily covers mechanics, gravitation, and harmonic motion. Depending on the available time, a brief introduction to material on waves, relativity, and fluids necessary for later course work may also be presented. Physics 122 is a calculus- based course intended for Physical Science, Engineering, Mathematics and other Technical majors. The course is intended to provide the student with a strong foundation for future course work in these fields as well as improving the student’s general problem solving skills.

Grading: The final grade for Physics 122 will be based upon written examinations, quizzes, homework and lab work. At least two exams will be given during the semester as well as a comprehensive final. These exams are comprehensive and will test both the student’s conceptual and analytical abilities. Unannounced quizzes may also be given during labs and class in order to discourage test cramming and to ensure that students develop the necessary study habits needed for success in PHYS122. Homework will be assigned regularly and collected using the automated homework system WebAssign. Students are required to keep a notebook with each homework problem workout on paper using the method presented in the homework handout. The instructor will collect these solutions randomly and grade them for clarity, logic, and correctness. The remaining portion of the student’s grade will be determined by group activities including lab work and projects. The student must successfully complete at least 80% of the lab assignments in order to pass the course. Time: Because Physics 122 requires students to use math and science skills learned in other classes as well as learning and study skills beyond simple memory and recall, it is a challenging course for most students. However, most students even those with poor backgrounds can succeed in Physics 122 if they develop the necessary study skills and consistently spend the required time. Students should consider their academic, work, and outside activity schedule to see if they have sufficient time to dedicate to PHYS122. A student should expect to spend between 3 and 5 hours outside of class for every 1 hour of lecture depending on the student’s background and the material in order to pass PHYS122. In order to be successful, it is important that the student develops a consistent study schedule instead of cramming for quizzes and exams. The student should perform the pre-class assignments of the web for each particular module. The student’s study program should include working through each equation in the textbook, reviewing previously covered material, working problems, and noting questions for the instructor. The process of learning physics is similar to that of learning to play football or the flute in that it is not a spectator activity. Each student is expected to come to class with questions and prepared to engage in an interactive discussion with the class and instructor on the assigned material. Students should make frequent use of the instructor’s office hours whenever they are having difficulties. In addition to posted office hours, students should feel free to come for assistance anytime the instructor is in his office. Students can also contact their instructor for help using e-mail or the WebAssign help desk.

Pre/Post Class Work: In order to master the material in PHYS122, students may have to work through the reading assignments multiple times using pen and paper. Prior to class, the student should make a quick reading of the chapter and record any areas of confusion. During class, students will be required to participate in an active learning process including the answering of questions. To reduce time spent taking notes and to allow students to concentrate on the material, a detailed outline of class notes is provided on the web. Students are expected to visit the PHYS122 web site (http://www.math.tarleton.edu/Physics/courses.html) and to perform the assigned pre- class activities including reading assignment and the printing of class notes before every class. Following class, students are required to complete the post-class assignment including reviewing their notes and working assigned homework problems.

Homework: Homework will be assigned and collected using the automated homework system, WebAssign. (http://www.webassign.com). Universities from all over the country including the US Military Academy at West Point, US Naval Academy, Purdue, Massachusetts Institute of Technology, etc have found WebAssign to be a powerful teaching tool. Each student is provided a set of problems with their own unique set of numerical values. Upon completion of the assignment, the student will submit their answers over the Internet and receive immediate feedback. In order to improve the student’s ability and their grade, WebAssign will allow the student to rework the problems as many times as they wish until the assignment’s due date. If a student finds that they do not understand the solution to a particular problem or have spent more than 30 minutes on one problem, they are encouraged to seek help from the instructor. Students should consider these assigned problem sets to be the minimum number of problems that must be solved to successfully complete Physics 122. Additional problems with solutions are also contained on the many physics links on the PHYS122 web site and in their Schaum’s Outline Series. If a student is having difficulty is a particular area, the instructor will be glad to suggest additional problems and to provide solutions. Students are further encouraged to study together in groups and to use the chat rooms and bulletin board on the PHYS122 web site to discuss physics and to work homework problems with their class mates.

Attendance: Although there is no mandatory attendance policy for Physics 122, it is highly recommended that students make every attempt to make all classes. If a student must miss a quiz, exam, or lab due to an emergency or illness, they should contact the instructor as soon as possible. If the instructor decides that the absence was excused, the student may be given a make up quiz, exam or lab or the instructor may alter the weighting of the student’s other grades. If the absence is unexcused then the student will receive a zero for the missed graded event.

Lab: In order to receive credit for the course, a student must complete the lab portion of the course by successfully finishing all lab assignments. If a student receives a zero for missing a lab, they must still arrange a time with the instructor to complete the lab in order to complete the course. During lab, computers are only allowed to be used for lab work. They are not to be used while the instructor is presenting material or to complete homework assignments without instructor approval. Students not working with their team on their labs will be given a grade of zero and required to make up the lab. You are expected to be in lab the full time unless you have obtained special permission from the instructor. Do not schedule other activities including doctor appointments during this time. Lab computers are for data collection and analysis only during the Lab period. You may not use them for web surfing, doing homework, sending email, or other non-lab uses during the lab period without instructor permission. Violating this policy will lead to the student getting an “F” for the lab.

Honors Credit (Fall Only): Members of the Presidential Honors Program or strong academic students who wish to be challenged and have an interest in physics or applied physics areas like medicine, engineering, etc may take PHYS122 for Honors credit. PHYS122 Honors students will have the opportunity to have a greater understanding of physics through additional enrichment projects including more reading assignments. The reading assignments will include advanced material from the Feynman Lecture Series Volume I that was developed by Nobel Prize winner Richard Feynman for the introductory physics course at the California Institute of Technology. Enrichment will also include special advanced laboratory exercises that normally are reserved for more advanced students or involve expensive instrumentation.

Other Opportunities: Physics 122 students have access to a wide range of professional opportunities outside of class. These include a) working with Tarleton’s particle accelerator on problems in material science and physics or with Tarleton’s 32” Telescope. b) joining the Society of Physics Students (SPS) at Tarleton, c) attending the joint meeting of the Texas Section of the American Physics Society (APS) and American Association of Physics Teachers (AAPT) in April at Tarleton State University d) joining the Institute of Electronics and Electrical Engineers (IEEE) e) joining the Engineers Club f) doing science demonstrations at area schools Tarleton installed a new particle accelerator laboratory and a scanning electron microscope in 2001-2002. The accelerator facility is worth more than $1 million dollars and was donated by the California Institute of Technology. It will be used to analyze electronic materials and to perform basic research in to ion atom collisions. A new x-ray facility is also being installed. Tarleton has a state-of-the art astronomical observatory as well as the finest scanning electron microscope of any undergraduate institution in the country. Students interested in these projects should contact Dr. Marble and Dr. Goderya.
