Understanding the Factor Label Method

Mr. Anderson introduces the factor label method, also known as dimensional analysis, for solving conversion problems. He uses the Six Degrees of Separation analogy to explain the concept. The video includes examples of converting days to hours, days to seconds, and miles per hour to meters per second. Mr. Anderson emphasizes the importance of using conversion factors and highlights the method's limitations, such as its inability to handle conversions involving non-linear relationships like Fahrenheit to Celsius.

What is another name for the Factor Label Method?

• Mathematical Analysis

• Dimensional Analysis

• Scientific Notation

• Unit Conversion

What is the main idea behind the Six Degrees of Separation analogy?

• Everyone is connected by six or fewer social connections.

• It takes six steps to solve any problem.

• There are six main scientific methods.

• Six is the maximum number of units you can convert.

What is the first step in the Factor Label Method?

• Multiply the given quantity by a conversion factor.

• Solve the math problem.

• Express the given quantity as a fraction.

• Cancel out the units.

When converting days to seconds, which of the following is NOT a necessary conversion factor?

• Seconds to milliseconds

• Minutes to seconds

• Hours to minutes

• Days to hours

How many significant digits should the answer have when converting 12 days to seconds?

• Three

• Four

• Two

• One

What is the correct conversion factor for miles to meters?

• 1 mile = 169 meters

• 1 mile = 1609 meters

• 1 mile = 5280 meters

• 1 mile = 1000 meters

Why do conversion factors have an infinite number of significant digits?

• They are rounded numbers.

• They are derived from experiments.

• They are exact values.

• They are approximations.
