Transcript of Dimensional Analysis
Understanding dimensional analysis.
Why is dimensional analysis important?
How dimensional analysis applies to you and me? Dimensional: (di-men-sion)- the measureable extent of something?
Extent Analysis: (a-nal-y-sis)- to examine parts of something.
Look at What does DA do? DA helps create an understanding of measurements. DA is a format for comparing measurements.
Example: Scientific Method System of Measurement Standard
System International What can we measure? Mass
Gases What is an equality? An equality is the relationship
between two numbers or quantities
of different units. Examples? 100 pennies = 1 dollar
60 minutes = 1 hour
1 day = 24 hours
1 football field = 100 yards Mass = grams
Length = meters
Volume = liters
Temperature = degrees DA helps explain the differences in measurements.
DA makes something understandable for the desired unit.
DA is done by UNIT CONVERSIONS or the line factor method.
Unit conversions contain several parts.
A numeric value
A desired unit
The conversion factor I go to the store to buy some mangos.
Mangos cost $0.60 cents a pound (lb).
How much will it cost me if I buy 3.5 pounds of mangos.
What is the numeric value?
What is the desired unit?
What is the conversion factor?
What is dimensional analysis?
UNIT CONVERSION! We are looking at measurements.
