```					CHAPTER 1
Section 1.1
 Why study Physics???
 Study of…
 matter…energy…and it’s behavior.

   Careers associated with Physics…
   Examples…
   http://www.physics.org then click
careers
Section 1.2

 Talking Physics…
 *Must be specific… why?
    example… speed and velocity
               mass and weight
Section 1.3

 Importance of Units
      V=volume and V=volts expected to know
which within the context of the problem.

 Ratios and Proportions
 Practice problems
     Ex. 1.1 Practice problem 1.1 and
Checkpoint 1.3
Section 1.4

 Scientific Notation and the dreaded…

          SIG FIG’S

Section 1.5

 Units
    a) Metric system… power of 10
    b) Why Metric???
    c) Conversion factors
          example… 12 in to 1 ft.
   Practice Problems
      Ex. 1.5; practice problem 1.5
      Ex. 1.6; practice problem 1.6
      Checkpoint 1.5
Section 1.6

 Practice problems…
   Ex. 1.7; practice problem 1.7
   Ex. 1.8; practice problem 1.8

Section 1.7

 Approximations
 How do we approximate?
    Question… How many blades of grass are
there on the football field?

a) Fermi Quiz
b) Ex. Problem 1.9; Practice problem 1.9

Section 1.9

 Graphs
   a) independent variable
   b) dependent variable

 Things to remember…
   1) large and neat- why large?
       use at least a ½ sheet of paper
   2) label with meaningful title
Continued

        3) Straight edge to draw best line fit
        4) determine best fit by large range of
the graph. Use values from best fit line to get
slope.
         5) Use algebra to manipulate a non-
linear relationship
         6) An “outliner” should be
investigated. Perhaps more data close to
that point.
Continued

        7) You can use dimensional analysis to
analyze slope equations.

 Practice problems..
 Ex. 1.10; practice problem 1-10

 Accuracy and precision.
 Definitions…
