Distance-Time Graphs

Front

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

Back

The object is at rest (not moving).

Front

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

Back

The speed is determined by the slope of the line on the graph; steeper slopes indicate higher speeds.

Front

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

Back

The object is moving away from the starting point.

Front

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

Back

The object is moving back towards the starting point.

Front

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

Back

The speed of the object is changing (accelerating or decelerating).

Front

What is the significance of the y-axis on a distance-time graph?

Back

The y-axis represents the distance traveled by the object.

Front

What is the significance of the x-axis on a distance-time graph?

Back

The x-axis represents time.

Front

How can you identify when an object is moving at a constant speed on a distance-time graph?

Back

The object is represented by a straight line with a constant slope.

Front

What does it mean if a distance-time graph shows a line that returns to the x-axis?

Back

The object has returned to its starting position.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.
