Qualitative Graphs

Front

What is a qualitative graph?

Back

A qualitative graph is a visual representation that shows the relationship between two variables without using numerical values, focusing instead on the general trend or behavior of the data.

Front

What does a zero slope indicate on a graph?

Back

A zero slope indicates that there is no change in the value of the dependent variable as the independent variable changes, meaning the line is horizontal.

Front

What does a positive slope indicate on a graph?

Back

A positive slope indicates that as the independent variable increases, the dependent variable also increases, meaning the line rises from left to right.

Front

What does a negative slope indicate on a graph?

Back

A negative slope indicates that as the independent variable increases, the dependent variable decreases, meaning the line falls from left to right.

Front

In a distance-time graph, what does a flat line represent?

Back

A flat line represents a period of time where there is no change in distance, meaning the object is stationary.

Front

In a distance-time graph, what does a steep line represent?

Back

A steep line represents a high speed, indicating that the distance is changing rapidly over time.

Front

What does it mean if a graph shows a decreasing distance from a starting point?

Back

It means that the object is moving back towards the starting point.

Front

What does it mean if a graph shows an increasing distance from a starting point?

Back

It means that the object is moving away from the starting point.

Front

How can you determine the speed of an object from a graph?

Back

The speed can be determined by the slope of the line on a distance-time graph; a steeper slope indicates a higher speed.

Front

What does a section of a graph with a negative slope indicate about an object's motion?

Back

It indicates that the object is moving in the opposite direction, or that its speed is decreasing.
