Learning objectives
What the syllabus expects you to be able to do.
- 2.9.1Use and interpret graphs in practical situations, including travel graphs and conversion graphs, and interpret the gradient of a straight-line graph as a rate of change.
- 2.9.2Draw graphs from given data, such as a distance–time graph of a journey.
- 2.9.3Extended: apply rate of change to distance–time and speed–time graphs, including acceleration and deceleration.
