What is a speed-time graph?
- Speed-time?graphs show speed at different times
- Speed is on the vertical axis, and time is on the horizontal axis.
- The?gradient?of the graph is the?acceleration:Acceleration?= RISE / RUN = SPEED / TIMEArea?under graph = Distance covered
Horizontal?line = Constant speed (so zero acceleration)
Exam Tip
It is easy to get confused between different types of graph.
Look at the label on the vertical axis to make sure you are looking at a SPEED-time graph (not distance-time).
