Reading Distance-Time Graphs
Read and plot distance-time graphs for moving objects; interpret the gradient (steepness) of a line as speed; identify stationary periods (horizontal sections), constant speed (straight diagonal lines), and relative speeds by comparing gradients; calculate average speed from the gradient of a straight-line segment using speed = distance ÷ time
Typical age: 10–13 years
“If your child sees a distance-time graph of a journey with a flat section in the middle, can they explain what was happening then — and point to which part of the graph shows the fastest speed?”
