CHAPTER 1 Section 1 1 Why study

CHAPTER 1

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

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 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

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 Checkpoint 1. 6

Section 1. 7 Problem solving techniques… link http: //groups. physics. umn. edu/physed/Resea rch/CRP/psintro. html

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 nonlinear 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
