A distance-time graph is used to show how far an object has travelled over a period of time.

The overall distance travelled divided by overall time for a journey.

The gradient (steepness) of a line on a distance-time graph shows its speed. Higher gradients (steeper lines) show faster objects.

A stationary object is not moving. It has a speed of 0 m/s.

Interpreting distance-time graphs

Science

In the Measuring and calculating motion unit, they will build on this knowledge to learn how to measure and calculate velocity and acceleration, and how to interpret velocity-time graphs. 

In the Forces unit, pupils learn to accurately describe and explain the actions of forces in a range of situations.

The total distance travelled divided by the total time.

Shows the distance something has moved at each moment.

Another name for the gradient of a graph.

At what time does this object start moving closer? Include the unit in your answer.

Which of the objects shown by the four lines has the lowest average speed?

Which of the objects shown by the four lines has a speed of 0.13 m/s?

Calculate the average speed for this complete journey.

Calculate the average speed between 10 s and 30 s for this journey.

numbers on the axis so that values can be read

lines from the axes that allow readings to be read easily

Match the feature of the distance-time graph to what it is for.

Use the graph to find out how far this object has travelled in 60 s. Include the unit in your answer.

Use the graph to find out how long it takes this object to travel 6 m. Include the unit in your answer.

How far does this object travel between 10 s and 40 s?

Starting with the fastest, put the objects shown on the graph in order of average speed.

Use the graph to calculate the average speed of the object.
