Presentation Transcript

  1. Chapter 1

  2. Section 1.1 • Why study Physics??? • Study of… • matter…energy…and it’s behavior. • Careers associated with Physics… • Examples… • Link to careers • http://www.physics.org then click careers

  3. Section 1.2 • Talking Physics… • *Must be specific… why? • example… speed and velocity • mass and weight

  4. 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

  5. Section 1.4 • Scientific Notation and the dreaded… • SIG FIG’S • Rules for Sig figs… link • http://www.germanna.edu/tutor/Handouts/Chemistry/Significant_Figure_Rules.pdf • Practice problems • A)Worksheet B) Ex. 1.2; practice prob. 1.2 • Ex. 1.3; Ex. 1.4

  6. 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

  7. Section 1.6 • Practice problems… • Ex. 1.7; practice problem 1.7 • Ex. 1.8; practice problem 1.8 • Checkpoint 1.6

  8. Section 1.7 • Problem solving techniques… link • http://groups.physics.umn.edu/physed/Research/CRP/psintro.html

  9. 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

  10. 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

  11. 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.

  12. Continued • 7) You can use dimensional analysis to analyze slope equations. • Practice problems.. • Ex. 1.10; practice problem 1-10

  13. Additional Topics for Chap 1 • Accuracy and precision. • Definitions…

  14. Interactive site from The Physics Front • Measurement…uncertainty and sig figs • Practice http://www.saburchill.com/physics/chap03.html
