Assignments, problem set solutions and other course materials will be posted there. It is my assumption that you check WebCT daily to make sure you are not missing assignments, announcements or due dates. COURSE CONTENT: Physics 130 is the first semester of calculus-level physics for scientists and engineers. The class will cover all or parts of chapters 1 through 16, focusing on forces and motion, Newton's laws, gravitation, work and energy, momentum, rotational quantities, fluid dynamics, oscillations and mechanical waves (see Addendum B). It will be assumed that material from the first three chapters is review and therefore will not be covered in detail. See Addendum A on page 3 for Objectives/Student Learning Outcomes. PREREQUISITE: Successful completion or concurrent enrollment in Math 193 or an equivalent calculus course. GRADING SYSTEM Problem sets/Quizzes: Problem sets will be assigned on a regular basis throughout the semester. The problems will not be collected; however, quizzes will given approximately once a week that will cover the problem sets and lecture material. Solutions to most of the problems will be posted prior to the quiz dates. A thorough understanding of all lecture material along with diligent practice on problem sets should prepare one for the quizzes and exams (see Student Success on page 2). Midterm exams: There will be 3 midterm exams during the semester (tentative dates are given on page 2). No one is excused from exams without prior notification, except in an emergency. If an exam is missed, a make-up exam will be given at the discretion of the instructor. Make-up exams will not necessarily be of the same format or difficulty level. Note: prior notification means that I must receive a phone call or a voice mail before the scheduled time of the exam. Final exam: The final exam will cover material from the entire semester. Lab: Lab reports, computer assignments, problem sessions, worksheets, and lectures make up the lab grade. It is the responsibility of the student to make arrangements to complete any missed lab experiments. Late lab reports will have 10% per day deducted from the overall score. Note: there are no make-ups for missed labs where the grade was based solely on attendance and participation in lectures, problem sessions, and worksheets. Calculating Grades: Quiz average: Exam 1 (September 20): Exam 2 (October 25): Exam 3 (November 29): Final Exam: Lab average: 15% 15% 15% 15% 30% 10% Averages will be calculated using the above percentages and a grade will be assigned based on the cut-offs given below. A ≥ 83, B ≥ 68 , C ≥ 52 , D ≥ 40 , F < 40 ACADEMIC HONESTY: I encourage you to work together on take-home assignments. However, for your accomplishments in this class to be meaningful, all work on quizzes and exams € €a zero will € be given € on any exam where cheating is evident. must be your€own. Therefore, The students involved will be reported to the Dean of Student Life. STUDENT SUCCESS: To succeed in the class, my advice to you is the following. • STUDY AND REWRITE YOUR LECTURE NOTES as soon after class as possible. Read the text to help clarify and expand the lecture notes. After studying your notes, if there is anything you do not fully understand, attend office hours and ask questions. • WORK PROBLEMS. First, work the example problems and the exercises that are inside the chapters of the text. Then do the problem sets. Work at least one problem everyday. Write down the concepts that led to each problem's solution. There are hundreds of problems, but a much smaller number of concepts. A thorough understanding of the concepts and sufficient practice solving problems leads to better success in solving new problems that appear on quizzes and exams. • USE WEBCT to post questions and comments and to answer each other’s questions. Addendum A: PHYS 130 Objectives/Student Learning Outcomes • Identify the forces acting on an object. • Draw free body diagrams for objects. • Apply Newton's laws, at the calculus level, to solve problems involving static equilibrium and accelerated motion in one and two dimensions. • Apply the appropriate skill sets, at the calculus level, to problems involving conservation of energy and/or momentum, fluid flow, and rotational motion. • Apply the appropriate skill sets, at the calculus level, to problems involving simple harmonic motion and oscillations and waves in elastic media including sound waves in air.
