** Pre or Co-Requisite** : MATH 2710 (Calculus III)

Textbook: Engineering Mechanics: Dynamics by R. C. Hibbeler, 14th edition.

Please always have a scientific, preferably graphic, calculator with you at all times.

Dynamics is an interactive learning course with classroom demonstrations on the theory and application of engineering mechanics to bodies that are accelerating. General topics include kinematics, force and acceleration, work and energy, impulse and momentum as applied to the motion of particles and rigid bodies.

The overall objective is that the student is given a thorough introduction to the vector mechanics of accelerating objects. By the end of the course, the student should be able to:

- use calculus to find equations of motion in problems with arbitrarily defined accelerations.
- solve for a particle’s or rigid body’s position, velocity, or acceleration using rectangular, normal and tangential, and cylindrical co-ordinate systems.
- draw free body diagrams and use Newton’s second law to find a particle’s or rigid body’s equations of motion in rectangular, normal and tangential and cylindrical co-ordinate systems.
- find a particle’s or rigid body’s position or velocity using work, the work-energy theorem and conservation of energy.
- calculate power used and efficiency of machines.
- predict the outcome of impact using impulse, conservation of momentum, and coefficient of restitution.
- apply both the absolute and relative-motion analysis to find the velocity and acceleration of a rigid body undergoing general translation and rotational motion.
- calculate a rigid body’s or composite body’s moment of inertia using integration or the parallel-axis theorem.
- apply the scalar and vector formulation to calculate a particle’s or rigid body’s angular momentum.
- use conservation of angular momentum to predict a particle’s or rigid body’s motion.

Attendance: Your attendance will strongly correlate with your success in this course.

- Students enrolled for credit or audit are expected to attend all class sessions.
- Attendance is taken at the beginning of the class, if you come in after attendance has been taken, please inform me after class.
- Students that come in more than 10 minutes late are considered absent for the class.
- Absences from class do not relieve students from responsibility for missed assignments, material covered in class or exams.
- A student with excessive absences (15% of total class hours) may be dropped from the class.

Collaborative In-Class Sessions: We will be engaging in collaborative work most of our class meetings. Be respectful of your yourself, your peers and your environment. Arrive to class calm, well prepared and ready to contribute. Please clean your area before you leave class.

Reflective Journal: At the beginning of class each Monday you will submit a journal that contains an entry conceptually summarizing the previous week's material, i.e. the journal due Monday of the nth week will contain a summary of the material from week n-1. Please use the same spiral notebook for the entire semester.

Homework: Doing the homework is very important in understanding the physics, and the experience will serve you well on the tests.

- Homework will be assigned on a weekly basis.
- Due in class every Monday (unless specified)
- Late homework will not be accepted
- Approximately 10 problems will be assigned every week
- The homework assignments and solutions can be found on our class website, barbsphysics.net, under the homework tab.
- Answers to the odd numbered problems are in the back of your book.

** Guide lines for the homework format: **

- Use pencil so that errors may be erased.
- Only one sheet per problem.
- Don’t crowd your work. Each step: problem restatement, free body diagram, equations, calculations, and final answer (with unit vectors and units) should be on a separate line.
- Points will be deducted for every instance of a final answer lacking units

Quizzes: Thirteen quizzes are scheduled. Each quiz will be administered during the first 15 minutes of class on Mondays. Quizzes will be primarily based on in-class problems and homework. Your class attendance/participation, your reflective journal conceptual summary AND completing your homework are important to doing well on the quizzes. Both problem-solving skills and a conceptual understanding are important to your success. There may be multiple choice questions, free response problems, and/or brief explanations. You may continually build on an 8”x11” one-sided formula-only sheet that you can use for each successive quiz, the midterm exam and the final exam.

Midterm Exam: A mandatory comprehensive midterm exam will be given on Monday 3/4/2019, 6pm - 7:30pm in L-102. You may continually build on an 8”x11” one-sided formula-only sheet that you can use for each quiz, the midterm exam and the final exam.

Final Exam: A mandatory comprehensive final will be given on the last day of class. It can serve to replace a missed test or a lower test score. In the event that CNM closes on the day of the final exam, the final grade will be calculated based on all work assessed up to that point in the course. Students may generate an 8”x11” two-sided formula sheet for the final exam. You may continually build on an 8”x11” one-sided formula-only sheet that you can use for each quiz, the midterm exam and the final exam.** Our final exam will be in L-102 on Wednesday, April 24th from 6:00 pm to 7:30 pm.**

A = 90 – 100% B = 80 – 89% C = 70 – 79% D = 60 – 69% F = 0 – 59%

- Quiz average, with the lowest score dropped, will yield 25% of your semester grade.
- Homework average together with your collaborative group participation grade, with the lowest scores dropped, yields 15% of your semester grade. (Collaboration participation will be based on how well prepared you were for class, and how effectively you participated in each collaborative session.)
- Weekly reflection journal average, with the lowest score dropped yields 10% of your semester grade.
- Midterm yields 25% of your semester grade.
- Final exam yields 25% of your semester grade.

** Note: All students must receive a grade above 50% on the final exam in order to pass this course. **

** In the event CNM closes on the day of the final exam, final grades for students will be calculated based on all work assessed up to that point in the course. **

Academic dishonesty will not be tolerated. As a CNM student you agree to adhere to the CNM Integrity Policy , please click here for policy details.

We will accommodate students with disabilities documented by the CNM Disability Resource Center. During the first two weeks of the semester, those students should inform the instructor of their particular needs.

PaperCut is an element of the sustainability effort at CNM. Its purpose is to reduce paper usage. Each student has an online account with an allotment of 150 free printer pages per term. If this allotment runs out, additional pages may be purchased by the student. For more information, go to the PaperCut website: http://cnm.edu/papercut.

Graduating with an associate’s degree or certificate will make you more employable and will increase your earning potential for a lifetime. Getting your degree or certificate is your reward for the hard work and dedication you put into your studies at CNM. Set your graduation date today! Learn more at http://cnm.edu/graduation.

In an effort to respect all students, CNM has created smoke-free zones as well as designated smoking areas at all CNM locations. The use of tobacco products, including the use of chewing tobacco and e-cigarettes is limited to the designated smoking areas and banned from all other areas. View CNM’s policy on smoking at http://www.cnm.edu/about/smoke-free-campus. View a map of the designated smoking areas at http://www.cnm.edu/about/smoke-free-campus/designated-smoking-areas.
