Physics 253 Fundamentals of Physics I: Mechanics Dr. Fortner FW 204 mfortner@niu.edu Course Content Physics—the science of energy and matter. • • • • Mechanics—the motion (or lack thereof) of physical objects Physical quantities describe behavior Physical quantities are related to each other Theoretical relations predict behavior Mathematics • Tool for understanding physics • Algebra and trigonometry are essential (MATH 155) • Calculus will be used sparingly (co-requisite MATH 229) Course Topics 1. 2. 3. 4. 5. 6. 7. Measurement and motion Motion in two and three dimensions Newton’s laws of force Circular motion and gravity Conservation of energy Conservation of momentum Conservation of angular momentum Web Pages www.niu.edu/~mfortner/Phys 253.html • • • • Description and goals Lecture slides Laboratory handouts Assignments: www.masteringphysics.com • Grading scale Text: Giancoli, Physics for Scientists & Engineers Lectures Powerpoint slides • Corresponds to text sections in reading • Different than text • Students are responsible for both Demonstrations • Interactive questions • Physical demonstrations • Web and electronic media demonstrations Laboratories Experimental labs Problem labs Measurement techniques Story problem interpretation Data analysis Equation handling Data presentation Solution strategy 8 Experimental Labs 4 Problem Labs Problems and Quizzes Problems Quizzes Due the day of the quiz Multiple choice, short answer and problems Solutions and help available in the Help Room (FR 225) Throw out the lowest grade of the seven quizzes Use TA and instructor office hours for help if needed Final equal to two quizzes and covers the whole course Suggestions Skim the text before class to get a head start on the lecture. Don’t just take notes in class (try to also listen). Slides are on the web page and can be printed out. Do problems, they are great practice. Use additional web resources from the publisher. Ask questions: in class and in lab. next
