1.5 Measurements and Graphing

Front

What is the conversion from millimeters to centimeters?

Back

1 centimeter (cm) = 10 millimeters (mm). Therefore, to convert mm to cm, divide the number of millimeters by 10.

Front

If an object measures 25 mm, how many centimeters is that?

Back

25 mm = 2.5 cm.

Front

What does a line graph represent?

Back

A line graph shows the relationship between two variables, typically displaying how one variable changes in relation to another over time.

Front

What does it mean if a line graph is increasing?

Back

An increasing line graph indicates that the dependent variable is rising as the independent variable progresses.

Front

What is mass measured in?

Back

Mass is measured in kilograms (kg) or grams (g).

Front

What unit is used to measure the volume of an irregular object?

Back

The volume of an irregular object is measured in milliliters (mL).

Front

What is the definition of speed?

Back

Speed is the distance traveled per unit of time, often expressed in meters per second (m/s).

Front

How can you determine if speed is increasing or decreasing on a graph?

Back

If the slope of the line on the graph is rising, speed is increasing; if the slope is falling, speed is decreasing.

Front

What does it mean if an object's speed does not change?

Back

If an object's speed does not change, it is moving at a constant speed.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.
