What a distance-time graph shows
A distance-time graph is a picture of a journey: how far the object sits from its starting point at every moment of the trip. This lesson trains the two readings that unlock every such graph — what the steepness tells you, and what a flat line tells you.
What you know already
From Speed you already know how to average distance over time for steady motion. This lesson turns that arithmetic into a picture: the distance-time graph, where the steepness of every straight line is a speed and every flat stretch is a rest. It is the first graph-reading skill the motion topic builds on.
Key points of understanding
- A distance-time graph plots how far an object is from its starting point against time.
- A straight line means constant speed; the steeper the line, the larger the speed.
- A flat horizontal line means the object is stationary.
- A curve means the speed is changing — steepening is speeding up, flattening is slowing down.
This graph shows a moving object moving further away from its origin
This graph shows how the slope of a line is used to interpret the speed of moving objects. Both of these objects are moving with a constant speed, because the lines are straight.
