Distance-time graphs

Front

What does a distance-time graph show?

Back

A distance-time graph shows how far an object has traveled over a period of time.

Front

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

Back

A straight line indicates constant speed.

Front

What does a slope represent on a distance-time graph?

Back

The slope represents the speed of the object.

Front

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

Back

A horizontal line indicates that the object is not moving.

Front

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

Back

A curve indicates that the object is accelerating or decelerating.

Front

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

Back

Speed can be determined by calculating the slope of the line.

Front

If an object travels 20 m in 10 s, what is its speed?

Back

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

Front

What does it mean if the distance-time graph returns to the starting point?

Back

It means the object has returned to its reference point.

Front

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

Back

Total time is found by looking at the time axis at the end of the object's journey.

Front

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

Back

A steep slope indicates a high speed.
