1. Physics 253Fundamentals of Physics I:Mechanics Dr. Fortner FW 204 mfortner@niu.edu

2. 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)

3. Course Topics • 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

4. Web Pages • www.niu.edu/~mfortner/Phys253.html • Description and goals • Lecture slides • Laboratory handouts • Assignments: www.masteringphysics.com • Grading scale • Text: Giancoli, Physics for Scientists & Engineers

5. 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

6. Experimental labs Measurement techniques Data analysis Data presentation 8 Experimental Labs Problem labs Story problem interpretation Equation handling Solution strategy 4 Problem Labs Laboratories

7. Problems Due the day of the quiz Solutions and help available in the Help Room (FR 225) Use TA and instructor office hours for help if needed Quizzes Multiple choice, short answer and problems Throw out the lowest grade of the seven quizzes Final equal to two quizzes and covers the whole course Problems and Quizzes

8. 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
