Reading Distance/Time Graphs

Front

What is a distance-time graph?

Back

A distance-time graph is a visual representation that shows how the distance traveled by an object changes over time.

Front

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

Back

A horizontal line indicates that the object is stationary and not moving.

Front

What does a straight diagonal line on a distance-time graph represent?

Back

A straight diagonal line represents constant speed; the object is moving at a steady pace.

Front

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

Back

Speed can be determined by calculating the slope of the line on the graph; steeper slopes indicate higher speeds.

Front

What does a curve on a distance-time graph signify?

Back

A curve indicates that the speed of the object is changing; it could be speeding up or slowing down.

Front

How do you find the total time taken for a journey from a distance-time graph?

Back

The total time can be found by looking at the x-axis and identifying the time interval from start to finish.

Front

What does the area under the line in a distance-time graph represent?

Back

The area under the line does not represent a physical quantity in distance-time graphs; it is primarily used in velocity-time graphs to represent distance.

Front

If an object travels 20 meters in 10 seconds, what is its speed?

Back

Speed = Distance / Time = 20 m / 10 s = 2 m/s.

Front

How can you tell if an object has stopped moving on a distance-time graph?

Back

An object has stopped moving if the graph shows a horizontal line for a period of time.

Front

What information can you gather from the slope of a distance-time graph?

Back

The slope indicates the speed of the object; a steeper slope means a faster speed.
