Edexcel IGCSE Maths 復(fù)習(xí)筆記 3.3.1 Distance-Time Graphs
What is a distance-time graph?
- Distance-time?graphs show distance from a fixed point at different times
- Distance is on the vertical axis, and time is on the horizontal axis.
- The gradient of the graph is the speed:Speed =RISE / RUN=DISTANCE / TIME
- Straight?line = Constant speed
- Horizontal?line = Stationary (not moving!)
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 DISTANCE-time graph (not speed-time).
