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)

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.
