Assignments for 33-131: Matter & Interactions I Fall 2001 After each class discussion (or before, if you prefer), it is your responsibility to study carefully the assigned sections of the textbook before the next class discussion. Not all assigned sections of the textbook will be discussed in class. Read thoughtfully, do the “stop and think” activities, and write brief solutions to the exercises in a course notebook. Make a note in the textbook or your notebook of any questions you have about the material, and ask for clarification. Some time before the end of the second week, come visit Dr. Sherwood or Dr. Chabay in their offices. Credit is given for the visit. MONDAY TUESDAY WEDNESDAY THURSDAY FRIDAY Week 1: Aug. 27 Course overview and logistics; matter and interactions By Wednesday, read the course syllabus, the textbook preface, and study Sections 1.1 through 1.5.4 of the textbook. DUE tomorrow: basic mechanics quiz DUE at start of last class: basic mechanics quiz Computer modeling, part 1 Study Appendix A, Vector Review, do the exercises, and check your answers. Omit section A.2 on dot and cross products. Be sure to get any questions answered right away, because we will use vectors extensively.

This is not Hammerschlag Hall! Take the elevator to the third floor of Hamburg Hall and walk straight ahead. After you are forced to turn right, go through the glass door on your right (labeled Center for Innovation in Learning). Just past the CIL mailboxes, turn left down a hallway to room 3041 or 3039B. 01/08/27Assignments for 33-131: Matter & Interactions I Fall 2001 MONDAY TUESDAY WEDNESDAY THURSDAY FRIDAY Week 3: Sept. 10 Ball & spring model of solids; analyzing dynamical systems; explanation of Young’s modulus measurement for tomorrow’s lab Sec. 3-1-3.4.4 Workshop (optional) DH A325 7:30-9:30 PM DUE: Prob. 2.9, 2.10, 2.11, 2.13, Ch. 2 reflection* DUE by 11 PM: Turn in by FTP the program file for Computer Problem 2.2, and include answers to questions as comments in the program file Experiments: Young's modulus (Prob. 3.1); spring-mass (Prob. 3.3); brief lab worksheet due tomorrow DH A325 open 7-10 PM DUE at start of class: Turn in brief lab worksheet Analytical solution to spring-mass system Sec. 3.4.5-3.4.12 Computer: modeling a spring-mass system (Prob. 3.4) A copy of last year's exam will be on the course web site QUIZ on sections 3.1-3.4.12 of Ch. 3 Speed of sound in a solid: computational model; dimensional analysis; measurement Sec. 3.5-3.5.1 Week 4: Sept. 17 Buoyancy; pressure; applying Newton’s laws with unknown force laws Sec. 3.6-3.8.1 Work on selected Ch. 3 review questions and problems Workshop (optional) DH A325 7:30-9:30 PM DUE: Prob. 3.2, 3.4, 3.9, 3.11, 3.12, Ch. 3 reflection* Work and kinetic energy; demonstration of Prob. 4.1 (work and energy in Moon voyage) Sec. 4.1-4.3 Exam review (optional) DH A325 7:30-9:30 PM EXAM 6:30-8:30 PM Covers Ch. 1-3 Room to be announced No class today, but the instructors will be in the classrooms to answer questions NO QUIZ Conservation of energy; general properties of potential energy; gravitational energy Sec. 4.4-4.4.10 Week 5: Sept. 24 Energy graphs; applications of gravitational potential energy Sec. 4.5-4.5.5 Work on selected Ch. 4 problems Electric potential energy Sec. 4.6-4.6.2 Workshop (optional) DH A325 7:30-9:30 PM DUE: Short assignment; Prob. 4.6, 4.8 Computer: Energy in Moon voyage (Prob. 4.2); to be checked off in class, starting from an existing Moon voyage program, which will be provided QUIZ on sections 4.1-4.6.2 of Ch. 4 Rest energy in a multiparticle system; reflection on energy Sec. 4.7-4.8 * Reflection questions will be posted on the course web site, http://www.andrew.cmu.edu/course/33-131 Written homework is due at the start of last class of the day; programs are due at 11:00 PM. 01/08/27Assignments for 33-131: Matter & Interactions I Fall 2001 MONDAY TUESDAY WEDNESDAY THURSDAY FRIDAY Week 6: Oct. 1 Macroscopic spring energy; thermal energy; power Sec. 5.1-5.5 Workshop (optional) DH A325 7:30-9:30 PM DUE: Prob. 4.9, 4.10, 4.15, 4.16, Ch. 4 reflection* Computer: Spring-mass system with energy graphs (Prob. 5.1, to be checked off in class) Open and closed systems Sec. 5.6 Work on selected Ch. 5 problems QUIZ on sections 5.1-5.6 of Ch. 5 Air resistance (brief); sliding friction; irreversibility Sec. 5.10-5.12 Not covered on exams: Sec. 5.7-5.9.4 (air resistance) and Sec. 5.13-5.13.2 (resonance) Week 7: Oct. 8 Energy quantization; emission and absorption of light Sec. 6.1-6.2.5 Workshop (optional) DH A325 7:30-9:30 PM DUE: Prob. 5.10, 5.12, 5.13, 5.16, Ch. 5 reflection* Work on and observe energy spectra, including doing Prob. 6.7 (H spectrum) A copy of last year's exam will be on the course web site DH A325 open 7-10 PM Quantized vibrational energy levels; other quantized
