Simple Nature - Light and Matter

It can also be handy to have a relation involving velocity and position,eliminating time. Straightforward algebra givesv 2 f = v2 o + 2a∆x ,where v f is the final velocity, v o the initial velocity, and ∆x thedistance traveled.⊲ Solved problem: Dropping a rock on Mars page 49, problem 17⊲ Solved problem: The Dodge Viper page 50, problem 190.1.5 Self-evaluationThe introductory part of a book like this is hard to write, becauseevery student arrives at this starting point with a different preparation.One student may have grown up outside the U.S. and so maybe completely comfortable with the metric system, but may havehad an algebra course in which the instructor passed too quicklyover scientific notation. Another student may have already takenvector calculus, but may have never learned the metric system. Thefollowing self-evaluation is a checklist to help you figure out whatyou need to study to be prepared for the rest of the course.If you disagree with this statement.. .I am familiar with the basic metricunits of meters, kilograms, and seconds,and the most common metricprefixes: milli- (m), kilo- (k), andcenti- (c).I am familiar with these less commonmetric prefixes: mega- (M),micro- (µ), and nano- (n).I am comfortable with scientific notation.I can confidently do metric conversions.I understand the purpose and use ofsignificant figures.you should study this section:subsection 0.1.6 Basic of the MetricSystemsubsection 0.1.7 Less Common MetricPrefixessubsection 0.1.8 Scientific Notationsubsection 0.1.9 Conversionssubsection 0.1.10 Significant FiguresIt wouldn’t hurt you to skim the sections you think you alreadyknow about, and to do the self-checks in those sections.Section 0.1 Introduction and Review 23
