Transcript of Dimensional Analysis
What is it?
Writing Conversion Factors
Using Conversion Factors
A systematic approach to problem solving that uses conversion factors to move, or convert, from one unit to another.
Dimension = Unit, so D.A. = "unit analysis".
is a ratio of equivalent values having different units.
For example: 1 minute = 60 seconds can be written as a conversion factor, that allows us to convert from minutes to seconds, or seconds to minutes.
You already use dimensional analysis to solve problems. Consider the following problem:
How many pizzas do you need to order for 32 people if each person will eat 3 slices, and each pizza has 8 slices.
Conversion factors come from equality relationships such as:
1 pizza = 8 slices
1 dozen = 12 things
1 foot = 12 inches
1 liter = 1000 mL
For each equality, we can write two conversion factors.
Allow you to convert from one unit to another.
All units except the wanted unit cancel.
