PHY121 Mechanics January 15th, 2009 Introduction to course PHY121 Ar n Garc a-Bellido, Arie Bodek January 15, 2009 1 Goals of the course PHY121 is a survey course for physics and engineering majors Principles of mechanics and their importance in your (real) world Topics to be covered: motion (linear, rotational, harmonic) forces collisions work, energy conservation laws thermodynamics waves... Level: introductory university level (not high school!) Some knowledge of calculus is necessary, but techniques will be reviewed when needed No prior knowledge of physics is assumed PHY121 January 15, 2009 2 Prof. Aran Garcia-Bellido Lectures Who we are B&L 314, [phone], [e-mail] Office hours: Mon, 3-4 pm & Tue, 1.30-3 pm Prof. Arie Bodek Workshops, study modules, homework problems B&L 354, [phone], [e-mail] Office hours: Thursdays, 2-3 pm TAs: Dan Ambrose, Steven Bandes, Martin Collins, Ryan Nora, Kelly Sassin, and Jon Spalding Prof. Kevin McFarland (lab coordinator) [e-mail] To request changes in workshops or labs, contact Janet Fogg [e-mail] (Do not Email course instructors) PHY121 January 15, 2009 3 Who you are PHY121 January 15, 2009 4 Who you are PHY121 January 15, 2009 5 All engineering calculations and models are based on physics fluid flow, arteries, water fountains, commodes mechanics of breathing, walking, running, flying, standing all sports: curve balls, spin in tennis, drag in swimming, etc... motors, gears, wheels, ambulances, bikes, planes, boats buildings, doors, bridges, skeletons Chemical bond modeling Why should you be here? Computers do a lot of the work for you these days... but they are only as smart as the people that programmed them A basic understanding of the principles of mechanics is a necessary tool for engineers and scientists Furthermore, the capability to determine whether solutions to problems make sense is a skill that you all need to have PHY121 January 15, 2009 6 Course info Textbook: Giancoli, Physics for Scientists and Engineers , 4th edition The material covered in this course is covered in Volume 1 (Physics 122 will cover the material in Volume 2) Use also the Student Study Guide and selected solutions manual , by Frank Wolfs We will use BlackBoard for distributing course materials, making announcements, etc... Lectures, problems, workshop material is already there If you did not receive an email yesterday, let us know For registration issues, contact Janet Fogg (B&L 211) PHY121 January 15, 2009 7 Components 1: Lectures Conducted by Professor Aran Garcia-Bellido Focus on the concepts and interconnections of the material No substitute for reading the textbook! Read the chapter before the lecture Ask questions during lecture Will use lab demos, quizzes and conceptual questions during the lecture Slides will be available the day before the lecture, written notes will be uploaded after class We will use a Personal Response System (PRS) for in-class quizzes and concept tests Make sure you acquire one, and participate in class PHY121 January 15, 2009 8 Components 2&3: workshops & problems Coordinated by Professor Arie Bodek Workshops and study modules: Small group meetings with a trained workshop leader: review and discuss the same concepts covered in class Use study modules and solve problems to fix the ideas: learn from fellow students Attendance to workshop correlates with better grades: do participate! Problem sets: Absolutely critical for your survival in this course Struggle with them and make sure you understand the solutions and solving techniques to do well in this course Solutions will be posted the following week Due each Saturday by 5pm: First is due January 17! Put in TA boxes in B&L first floor, next to the entrance to the tunnels PHY121 January 15, 2009 9 Give you a hands-on experience with making measurements and interpreting data They are not run by us, but are required to get a grade in this course You have to do all 5 labs and hand in the reports Each lab has a prelab homework assignment which will be collected before the start of lab. No late prelabs can be accepted You will be contacted with more specific info by the lab instructors: begin on February 2nd Information, manuals, etc... at http://www.pas.rochester.edu/~physlabs Components 4: labs Labs Introductory Lecture: Tomorrow Friday Jan 16, Hoyt Auditorium, 3:25 pm, by Prof. Bodek PHY121 January 15, 2009 10 Probs+prelabs +workshop atScheme Exam1 Exam2 Exam3 Final Exam tendance+PRS quizzes 1 0% 22% 22% 15% 41% 2 22% 0% 22% 15% 41% 3 22% 22% 0% 15% 41% Three midterm exams (Feb. 26, Mar. 24, Apr. 21 at 8 am, Hubbell Auditorium) and the final (May 7, 4 pm Hubbell Auditorium) The lowest exa...
