Analyzing Graphs

Front

What does a constant speed look like on a distance-time graph?

Back

A straight line with a positive slope.

Front

What happens to the water level in a bathtub when the plug is removed?

Back

The water level decreases at a constant rate until the tub is empty.

Front

How can you represent a runner who slows down and stops on a distance-time graph?

Back

The graph will show a flat line (horizontal) during the time the runner is stopped.

Front

What does a graph showing a person riding an elevator up and then down look like?

Back

It will show an upward slope followed by a downward slope.

Front

What does it mean when grams decrease at a decreasing rate?

Back

The rate of decrease is slowing down over time.

Front

What is the significance of the slope in a distance-time graph?

Back

The slope represents the speed of the object; steeper slopes indicate faster speeds.

Front

What does a horizontal line on a distance-time graph indicate?

Back

The object is at rest; it is not moving.

Front

How can you tell if an object is accelerating on a distance-time graph?

Back

The graph will show a curve that gets steeper over time.

Front

What does a graph with a steep slope followed by a flat line represent?

Back

The object moved quickly and then stopped.

Front

What is the difference between constant speed and variable speed on a graph?

Back

Constant speed is represented by a straight line, while variable speed is shown by a curve.
