Understanding the Delta Symbol: A Guide to Units of Measure

This video tutorial explains the delta symbol, which represents the change in a unit of measure. It focuses on the concept of change in time, where the final time is subtracted from the initial time to find the difference. An example is provided using a cookie tray in the oven to illustrate delta T. The video concludes by emphasizing that this method applies to various physical properties like temperature, velocity, and mass.

What does the delta symbol represent in measurements?

• The change in a unit measure

• A constant value

• The average of two values

• The sum of two measurements

In the cookie baking example, what is the initial time?

• 10:05

• 10:15

• 10:30

• 10:25

How do you calculate the change in time?

• Add the initial and final times

• Multiply the initial and final times

• Subtract the initial time from the final time

• Divide the final time by the initial time

Which of the following is NOT a physical property that can be measured using the delta symbol?

• Temperature

• Velocity

• Color

• Mass

What is the main takeaway when you see the delta symbol in measurements?

• Divide the final measurement by the initial measurement

• Subtract the initial measurement from the final measurement

• Multiply the measurements

• Add the initial and final measurements
