This is the first semester of a three-semester introductorycourse in physics for science and engineering students. This semester we will study Mechanics.Almost everyone is required to take this course as the first step in the study of their major. Thereason that your major requires you to take this course is to prepare you for work in your chosenfield by:• Having a solid understanding of the way the real world works based on a very fewfundamental principles of physics.• Being able to solve problems by applying these very few fundamental principles of physicsboth qualitatively and quantitatively.• Being able to decide on the applicability of these very few principles.• Communicating technical information in an organized and intelligent manner.The pace of this course should allow you to understand the material in depth, but it does moveright along. Don’t fall behind. It is extremely difficult to catch up and the longer you leave it,the harder it gets. You need to actively participate from day one by thoroughly reading the bookand the lab manual, by doing the homework problems and as many problems from the book asyou possibly can (at the very least, think about the physics needed for those that you do notexplicitly solve) and by making sure you get all your questions answered during office hours. Wewill require that you always use and communicate a logical and organized problem solvingtechnique; you will get very few points for just giving the correct answer on the quizzes and final(this will not apply to the multiple choice questions of course). We assume that you have a goodworking knowledge of algebra, geometry, trigonometry, and basic acquaintance with thedifferential and integral calculus; additional mathematical techniques will be introduced whenneeded. What you get out of the course will depend on the productive effort and quality time youput into it; all the help you need is readily available! Remember that mechanics describes the realworld so relate the material to your everyday experiences!2

Lecture: During lectures you will be introduced to fundamental physical concepts and shownhow to apply these concepts to solve specific problems. You are expected to read the relevanttextbook chapters before coming to class. You are always invited to think critically about thematerial presented, ask questions and clarifications whenever needed. It is important that youunderstand the material presented since it will be required to understand concepts introducedlater on.In-class questions (ICQ): From time to time during lectures you will be asked several short,multiple choice questions. Your answers will be collected using a responder system. You willtypically have 1 minute to answer each question. These will be graded as follows: correct – 2points, incorrect – 1 point, no answer – 0 points. It is your responsibility to make sure that yourresponder is set up correctly (e.g., programmed with your student ID) and functions properly(e.g., has fresh batteries). A user manual is posted on the class website.Laboratory: Because this course satisfies University requirements as a laboratory science classand as a writing intensive course, you must pass the laboratory (60% of the possible marks)to receive a passing grade in the course; note that your use of English and your grammar areimportant. As well as this, the laboratory grade will be based on well thought out predictions,collaborative skills as evidenced by effective group work, and a well organized and correctlywritten technical communication of the physics concepts of this course in your laboratory journaland laboratory reports. The specific part of the laboratory for which you will write a report willbe assigned to you by your instructor at the end of each laboratory topic (about every two-threeweeks). Reports should be about 4-5 typed pages including all necessary predictions, graphs,data tables, and calculations. Use of a word processor is required and such facilities are suppliedby the University. Reports must be given to your laboratory instructor for grading no morethan one week after they are assigned. Late reports will not be accepted. Graded reports willbe returned to you not later than your next laboratory meeting and may be revised, only withinstructor permission, to achieve a higher grade. If a revised report is allowed, it must be given toyour laboratory instructor within 2 days. Details of the laboratory grading are in your laboratorymanual. All the laboratory problems have sections called Prediction and Method Questions. Youshould hand in your answers to these sections to your TA by 5 PM two business days beforethe laboratory takes place. (Your TA will assign the lab problems during the previous laboratorymeeting.) To ensure that you have a conceptual introduction to the physics and math conceptsneeded for beginning the lab, you will take a quiz every week, except the first, on the web(http://myu.umn.edu/) to test your preparation for the lab. No one will be allowed to participatein the laboratory unless they have passed the web-based laboratory preparation quiz forthat topic. It is an open book, open note quiz which may be taken as often as necessary but mustbe passed at least one hour before your scheduled laboratory session; it does not counttowards your final grade. Because of the limited number of computers available, make sure totake this quiz at least the day before your lab meets. A passing grade is 75%; if you fail to passthe quiz after two attempts, get help. Failure to participate in the laboratory will result in alaboratory grade of 0 for that topic. Since the laboratory involves teamwork, no laboratorymakeup will be allowed except in situations officially recognized by the University. In that case,the laboratory work must be made up by arrangement with your instructor before your next3

scheduled laboratory period. If you expect to miss the lab period you should contact yourinstructor as early as possible.Recitations: Once a week you will solve 1-2 problems working in a group. This is intended to bea practice for the group portion of the upcoming quiz but will also help the individual portion. Itis important that you use your time wisely especially if you are offered more than one problem.The best practice is to attempt setting up both problems since this is the part where collaborativeeffort is most effective. Once this is done, it is in your best interest to do algebra on you ownwhich will help you with your individual part of the upcoming quiz. If you run out of time, makesure that you finish calculations and understand every step of the problem before the upcomingquiz. While solutions will be posted, it is in your best interest not to look at the solutions untilyou finish the problems.Quizzes: Four individual quizzes will be given on the dates stated at the beginning of thissyllabus. These quizzes will normally consist of 2 problems (25% each) and five multiple choicequestions (5% each) and will count for 75% of the quiz score. The remaining 25% of the scorewill come from a problem solved collaboratively by your group (group quiz) in the discussionsession (all group members get the same score). Note 10 minute rule: – if you arrive for thegroup quiz more than 10 minutes late you cannot join your group and will have to do theproblem by yourself. Failure to participate in one discussion session during the preceding weekswill result in 50% of the grade of the following group quiz. Failure to participate in twodiscussions will result in a zero for the grade of the following group quiz. The TA will assign thegroups and new groups will generally be assigned after each quiz. Quiz solutions will be postedon the class website.Homework: It is absolutely essential that you practice solving problems as often as you canby working out those at the end of the textbook chapter. It will do you little good to simply lookat the solutions. The most difficult part is setting up the problems so you need to attempt yourown solution before looking for help. The more problems you solve the better you will doon the exams. As the absolute minimum you should solve the problems listed below. Onsome occasions, you will be assigned extra problems. Some problems in the exams will beadapted from the homework problems, recitation problems, lecture examples, and samplequizzes (to be posted about one week before each quiz). While solutions for chapter problemsprovided by the publisher will be posted on the class website, you are expected to provide yourown solutions to the homework problems. In order to be able to effectively communicate,analyze and understand your result you should work the problem algebraically until the finalexpression is obtained and only then plug in the numbers. This will allow you to understand howyour result depends on the given parameters and to check that you have correct dimensionality.You will lose significant portion of your score if you do not follow this rule. Note, that postedsolutions often do not have the final result in the algebraic form and therefore can be used as aguide only. Some problems might not have any numerical values given. The homework shouldbe turned at the beginning of the discussion on the due dates. No late homework will beaccepted. A few problems from each set will be picked up at random and graded.4

I will not specify the ± dividing lines in advance.The quiz and final scores will not be curved or normalized to averages, but can be normalized toa few highest scores.Course evaluations: University expects each student to complete course evaluation at the end ofthe semester. As an extra incentive for doing so, I might add up to 3 points to the total grade ofthose who complete course evaluation.Tentative ScheduleWeek Topic Chapter Laboratory1 Units and Dimensions, Scalars and Vectors 1,2 FCI2 Kinematics of motion in 1D and 2D 2,3 Lab I3 Kinematics of motion in 2D (quiz 1) 3 Lab I4 Dynamics of motion, forces, Newton’s laws 4,5 Lab II5 Dynamics of motion, forces, Newton’s laws 4,5 Lab II6 Dynamics of motion, forces, Newton’s laws (quiz 2) 4,5 Lab III7 Energy and Work, Conservation of energy 6,7 Lab III8 Conservation of energy, linear momentum 7,8 Lab IV9 Conservation of linear momentum (quiz 3) 8 Lab IV10 Kinematics of rotational motion, rotational inertia 9,10 Lab V11 Dynamics of rotational motion, angular momentum 9,10 Lab VI12 Conservation of angular momentum, statics 9,10,11 Lab VII5

All students are expected to behave at all times withrespect and courtesy toward their fellow students and instructors and are expected to have thehighest standards of honesty and integrity in their academic performance. Any behavior whichdisrupts the classroom learning environment or any attempt to present work that the student hasnot actually prepared as their own work, or to pass an examination by improper means, isregarded as a serious offense which may result in the expulsion of the student from theUniversity. The minimum penalty for such an offense is a failing grade for this course. Aidingand abetting the above behavior is also considered a serious offense resulting in equally severepenalties. Open-Door Policy: If any difficalties or problems arise in this course that interfere inany way with your learning or optimum performance, please stop by or send an email to me orany of the TAs in the course. We will do our best to deal with problems promptly andeffectively.Make up quizzes: Since it is impossible to make up another test of exactly the same difficulty,there will be no make up quizzes. If you have a University acceptable excuse, your other quizzesand the final will carry more points. Other reasons (out of town research seminars, jobinterviews, etc) might be considered on a case by case basis. You also have an option ofdropping one of the quizzes for any reason. You can use for a family vacation, a friend’swedding, etc. If you are a student athlete and are out of town during the quiz due to a Universitysanctioned event, you should arrange for one of your coaches to pick up the quiz from the frontoffice just before you leave town. Your athletic organization will then administer the test atapproximately the same time the class takes it. They will then fax your solutions back to thefront office in time for them to be graded with the rest of the class. A coach will then return theoriginal of the student solution to the front office as soon as the team returns to town.Make up final: There will be no early finals given for any reason. The only make-up final isgiven the morning following the official final, usually at 8am. To get a make-up final you musthave two finals scheduled at the same time, 3 finals scheduled on the same day, or a Universitysanctioned excuse. If you cannot take a final the next morning, you can wait until the nextsemester and take the final with the next class. Statistics shows that students who take the makeupfinal get significantly lower grades than those who take the official final.Make up labs: There will be no make up labs. If you have acceptable University excuse you canattend another lab section that same week. You will need to contact your TA to arrange this. Ifthe lab is overcrowded, your request may be denied.Make up recitations: There will be no make up recitations. Unless you have a Universityacceptable excuse, for each missed recitation you will loose 50% of your group score on theupcoming quiz. If you have a University acceptable excuse, your final will carry more points.6

Make up ICQ: Since the answers for ICQ will be displayed in real time there is no make uppossible. You are allowed to miss two ICQ for whatever reason. You are also allowed to droptwo lowest ICQ scores. If you miss more than two ICQ quizzes, your final will carry morepoints. Keep in mind that the ICQ averages tend to be significantly higher than the finalaverages.Announcements: It is occasionally necessary to change schedules, including the date of quizzes.Students are responsible for ALL announcements made by email, during the lecture, recitation orlaboratory period. For your convenience, I will try to post most important announcements on the‘Class News’ web page. Missing an announcement is not an acceptable excuse for missing a quizor a course related deadline. It is the sole responsibility of any student missing a lecture todetermine what course material and announcements were missed.Students with disabilities: Students with disabilities that affect their ability to participate fullyin class or to meet all course requirements are encouraged to bring this to the attention ofDisabilities Services (230 McNamara) so that appropriate accommodations can be arranged.Resolving Disputes: If you have a dispute about a grade, your first address is your TA. He willeither explain to you the criteria set for grading or will forward your complaint to the TA whograded the problem. If you were still not satisfied with the response you got from the TA I willbe glad to sort it out.7
