Student Responsibilities Become a “Critical Thinker” –Make your method clear. –Go beyond: Did I get the right answer? Am I done yet? –Study groups vs. independent work. Integrity Self Reliance Slippery Slope –LON-CAPA - Submit on time.

Problem Solving Technique Read the problem. Reread it if necessary. Write down the information that is “given.” Write down what is to be “found.” Draw a picture or sketch. Write down the fundamental physical relationship necessary to solve your problem. Perform the mathematics (algebra, trig, calculus). Remember the rules for significant digits. Simultaneously, perform unit analysis. Box your final answer. Include units. Check that your answer makes sense. Picture Solve Check

Student Responsibilities Exams/Quizzes –Quiz regularly-don’t have to make up –Three exams Homework Labwork – one report per group CPS Board Work Bring your book and calculator to all classes and labs Steady Pull

Relevance “a gentleman of refined manners, liberal education, and the nicest sense of personal honor.” The navy is technical. Math is important. Admittedly not essential. It adds richness to your understanding. It is often the language of science. Calculus was invented to explain Physics! Physics is not just memorizing equations. Physics attempts to explain how things fundamentally work.
