Tipler, and Gene Mosca. This textbook is quite good and contains many useful examples. Although it is advertised as being for scientists and engineers, there are plenty of good biological problems and applications. Topics and Outlook: This course will introduce the basic ideas of Newtonian Mechanics, with a particular emphasis on the applications of these ideas to biological problems. This is a very large and interesting area of physics, and after the completion of this course you will understand the application of many areas of physics to the world of biology. We will begin with a thorough discussion of motion, including motion under the influence of gravity. After this, we will ask, where does this motion come from? What makes things move? The answer to these questions is found in Newton s laws of motion. These three laws really encompass all the main ideas of motion - everything else is application, and can be obtained from these laws, as we ll see. Following our discussion of Newton, we will then discuss one of the most important concepts in all of physics - the conservations laws. We will see that there are some quantities that, no matter how we twist and turn our system, these quantities always stay the same. This makes solving problems considerably easier. Next, we ll discuss gravity in more detail, followed by a little bit of statics and elasticity, and then fluids. Finally, the last topic will be systems which are vibrating. We ll begin with those that are just vibrating in place: say a mass on a spring, or a pendulum - systems that just vibrate in time. Then we will generalize these ideas to systems that are vibrating in both time and space - vibrations that move along. These are traveling waves. This will complete our study for the course. Applications to biological problems will be presented throughout the course. We will see how so many different questions can be answered by a simple application of the ideas that we ll discuss. We ll be able to answer questions such as, how much force is exerted on my muscles when I m holding a weight? Or how hard am I hit if I m in an accident? How does a centrifuge separate blood? Does blood flow faster or slower when it goes from a vein to a capillary, and why? These answers, and so many more will be within our reach. Physics is the most fundamental science, and explains all of biology. It is the purpose of this course to help you begin to see this. 1

Wednesday May 12 8:00 11:00 Grading: The grading will be based on the final (25%), two midterms (20% each), 15 homework sets (25% total), and the discussion/lab sessions (10% total). Homework There will be 15 homework assignments, each assigned on Wednesdays, and due by the beginning of class the following Wednesdays, giving you one week to finish them. We will do our best to give plenty of partial credit, so always attempt the problems, even if you don t finish them. Because the homework solutions will be posted immediately, no late homework will be accepted! While you are of course permitted (and even encouraged) to work together, it is your responsibility to complete, understand, and hand in your own assignment. Exams Midterm: There will be two midterms, tentatively scheduled for Friday, February 26th, and Wednesday, April 7th. The midterms will be cumulative, and will cover the material covered up to that point (although later material will likely be emphasized). Final: Wednesday, May 12: 8:00-11:00. The final exam will be comprehensive. Both exams are closed book. If some complicated formulas are needed (such as a nasty integral) they will be provided, as will any required numerical values, etc. You may use calculators. You should bring your student ID along so that your identity may be verified, if necessary. 3
Physics 18 page 4/6 Discussion/Lab Sessions Part of the course includes a discussion/laboratory (DL) session, led by Mark Kerfoot and Christiane Pailo. These sessions meet twice a week and will contribute a large amount to the course, so it is important that you attend these. During certain sessions you will perform experiments, while during others you will work problems. These DL meetings contribute 10% to your grade, and are manditory. The TAs are in charge of the DLs! 02C (4383) MW 2:00 p.m. 3:50 p.m. SE Building 107, TBA 03C (4384) MW 4:00 p.m. 5:50 p.m. SE Building 107, TBA 04C (4385) MW 6:00 p.m. 7:50 p.m. SE Building 107, TBA There will be nine labs each meeting during your regularly scheduled DL time.

Physics 18 page 6/6 Academic integrity Academic integrity is the foundation of an academic community and without it none of the educational or research goals of the university can be achieved. All members of the university community are responsible for its academic integrity. Existing policies forbid cheating on examinations, plagiarism and other forms of academic dishonesty. The current policies for UC Merced are described in the UC Merced Interim Academic Honesty Policy and Adjudication Procedures available from Students First Center, Student Life, Residence Life and College One. Information is available through the Student Judicial Affairs link on the Student Life web page. http://studentlife.ucmerced.edu/. Examples of academic dishonesty include: Receiving or providing unauthorized assistance on examinations. Using unauthorized materials during an examination. Plagiarism - using materials from sources without citations. Altering an exam and submitting it for re-grading. Fabricating data or references. Using false excuses to obtain extensions of time or to skip coursework. The ultimate success of a code of academic conduct depends largely on the degree to which the students fulfill their responsibilities towards academic integrity. These responsibilities include: Be honest at all times. Act fairly toward others. For example, do not disrupt or seek an unfair advantage over others by cheating, or by talking or allowing eyes to wander during exams. Take group as well as individual responsibility for honorable behavior. Collectively, as well as individually, make every effort to prevent and avoid academic misconduct, and report acts of misconduct which you witness. Do not submit the same work in more than one class. Unless otherwise specified by the instructor, all work submitted to fulfill course requirements must be work done by the student specifically for that course. This means that work submitted for one course cannot be used to satisfy requirements of another course unless the student obtains permission from the instructor. Unless permitted by the instructor, do not work with others on graded coursework, including in class and take-home tests, papers, or homework assignments. When an instructor specifically informs students that they may collaborate on work required for a course, the extent of the collaboration must not exceed the limits set by the instructor. Know what plagiarism is and take steps to avoid it. When using the words or ideas of another, even if paraphrased in your own words, you must cite your source. Students who are confused about whether a particular act constitutes plagiarism should consult the instructor who gave the assignment. Know the rules ignorance is no defense. Those who violate campus rules regarding academic misconduct are subject to disciplinary sanctions, including suspension and dismissal. 6
