Distance - Time Graphs

Front

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

Back

Stopped (at rest)

Front

What does a straight line with a positive slope indicate on a distance-time graph?

Back

Constant Speed (positive slope)

Front

What does a straight line with a negative slope indicate on a distance-time graph?

Back

Return Home (negative slope)

Front

What does a curve that slopes upwards indicate on a distance-time graph?

Back

Acceleration (increasing speed)

Front

What does a curve that slopes downwards indicate on a distance-time graph?

Back

Deceleration (decreasing speed)

Front

How can you determine the speed from a distance-time graph?

Back

The speed is the slope of the line; steeper slopes indicate higher speeds.

Front

What does a steeper slope on a distance-time graph mean?

Back

Higher speed.

Front

What does a flat line followed by a steep line indicate on a distance-time graph?

Back

The object was at rest and then started moving at a constant speed.

Front

If a distance-time graph shows a line that is horizontal for a period, what can you conclude?

Back

The object is not moving during that time.

Front

What does it mean if the distance-time graph has a line that is straight but not horizontal?

Back

The object is moving at a constant speed.
