Physics 212 College Physics II Introduction Instructor: Larry Watson Office: 105 Witmer Phone: 777-3525 e-mail: [email protected] web: und.nodak.edu/instruct/lwatson/212 Textbook “Physics” by Cutnell and Johnson, fifth edition Lab Text “Introductory Physics Laboratory Manual” Labs 212 labs are on Mondays and Tuesdays beginning Jan 27 (Next week) Attendance is mandatory! You must complete all labs to pass the course! 15% of course grade No labs Jan 20-24 (Monday holiday) Homework Assigned daily Collected randomly, beginning of class Two late assignments accepted by 5 p.m. same day Two lowest scores dropped 25% of course grade Exams Four two-hour evening exams (5-7 Thursdays) Two hour final Final is on Tuesday, May 13, 10:15 a.m. Please make travel plans accordingly as I CANNOT change this date or give early finals! Questions are “explain your reasoning” type Exams No multiple choice Explain your reasoning-show your work Correct numerical answers not the most important thing Quality thinking is important Grading Grading Scale: 90 or above = A 80 or above = B 70 or above = C 60 or above = D The lower cutoff may be lowered, if necessary, but never raised. Lecture Active participation by YOU! Practice problems Life threatening demonstrations! I prefer discussion so: ask questions make comments… Take notes? Study Ideas Start HW the day it is assigned! (I will take questions the next class day.) Study some each night. Work in groups. Doing Homework Do something even if you think it’s the wrong thing--use hindsight to evaluate your work. Don’t try to write your final solution on the first try, use scratch paper. Draw a diagram or picture. Write large. Neatness counts! Web Site Lectures (power point) Homework (from text or in word format) Practice problems Old exams Caution: Printing lectures can be time and paper intensive. You can print up to 6 slides per page. Content Waves sound, light, interference Optics refraction, reflection, lenses, mirrors, images Electricity and Magnetism charge, force, E fields, circuits, resistance, capacitance, B fields, induction Other topics? fluids, nuclear, quantum, thermodynamics Things to think about: Consider a traveling wave: sound, light, football stadium, water... How would you define a “wavelength?” How would you define a “frequency?” How would you define a “wave velocity?” How does the direction of the wave’s motion compare to the direction of the individual particle’s motion? What happens when two waves run into each other?
