I. COURSE DESCRIPTION An algebra-based course covering the principles of thermodynamics, electricity, magnetism, and light for those contemplating the study of biology, medicine, etc. Lecture and Laboratory. Prerequisite: Physics 201 (General Physics I). Offered every semester. (4 Semester Hours) II. MAJOR FOCUS There are two ways that beginning students of physics can understand the topic: (a) through mathematical models, and (b) through concepts. This course uses both approaches. General Physics is an introductory course in physics, which uses methods developed in precalculus to describe physical phenomena. The tests are designed to measure a student's ability to apply the principles of physics to concrete situations. A firm grasp of the basic concepts and much higher-level thinking is necessary for a student to be successful on these tests. "You know you can't enjoy a game unless you know the rules -- whether it's a ball game, a computer game, or simply a party game. Likewise, you can't fully appreciate your surroundings until you understand the rules of nature. Physics is about the rules of nature -- so beautifully elegant that it can be neatly described mathematically." -- Paul G. Hewitt III. OBJECTIVES 1. You should know and be able to apply the principles of the following topics in explaining common phenomena: Temperature: what it is and how you measure it Thermal Expansion: of solids, liquids and gases, and the special case of water Heat Capacity: how adding heat changes the temperature of an object, and by how much Ideal Gas: the Ideal Gas Law and how to apply it Change of State: Latent heats, and how to use them in calorimetry problems Coulomb’s Law: the (vector) forces between two or more charged objects Electric Fields: how charges produce the field and how it affects other charges Electric Potential Difference: what it is and how it relates to electric field Capacitance: electrical energy storage, and how it is used in electrical circuits Electrical Current: the motion of charges and how to measure it Resistance and Ohm’s Law : how to apply Ohm’s law to electrical circuits Power: how to calculate power supplied and used in circuits Kirchhoff’s Laws: use these laws to calculate currents in complex circuits Use of Voltmeters, Ammeters and Ohmmeters: part theory and part lab experience Magnetic Fields: What they are, what makes them, and how they affect moving charges

2. The student will develop an understanding of the mathematical tools and techniques for analyzing and solving a wide variety of physics problems. 3. The students will know the historical origins and evolution of thermodynamics, electricity and magnetism, and optics. Especially important are the figures of Franklin, Coulomb, Ampere, Volta, Oerstead, Faraday, Maxwell, Newton and Snell. IV. TEACHING AND LEARNING STYLE This is an intensive course, with 5 lectures and 3 laboratory sessions per week. You will be expected to have read the assignment before the lecture and to have attempted any suggested problems by the next lecture. Homework problems will be posted on the Web using WebAssign, an interactive site, which will allow you to calculate and submit your answers and get instant feedback 24/7. Each assignment will have a submission deadline after which answers will not be accepted. The instructor will use class time to (1) demonstrate concepts covered in the reading material, (2) show relevance of the concepts to the contemporary world through specific examples, (3) show the historical context or the subject matter, (4) demonstrate problem solving techniques, and (5) answer questions from class. V. EVALUATION Your grade will be determined by combining the scores on lab reports, three exams and a Comprehensive final exam. The exams (except the final) will be a combination of 10 multiple choice and/or short answer questions (30 points) and 7 problems which involve calculations and must be worked out in detail (70 points). The final exam will be approximately twice as long. The weighting of the various scores is as follows: 3 exams @ 100 points each 300 points Homework 100 points Lab Reports 100 points Final Exam 200 points TOTAL: 700 points VI. POLICIES You are expected to attend and participate in class. Class exams are announced well in advance and you are obliged to take tests at the scheduled times. There will be no make-up exams. Dishonesty on a test will result in forfeiture of that test grade. During testing times students are expected to sit as far from neighbors as possible. One 8 ½” x 11” sheet of notes (both sides) may be used during each exam. You may have any notes, equations, graphs, examples or inspirational sayings you wish on your note sheet.
