Lesson details
Key learning points
- Distance-time graphs tell you how far you have travelled over a period of time.
- By reading the graph, you can tell if there is mistake with it.
- You can sketch a graph based on the information you have been given.
- Important given values should be marked on your sketch.
Common misconception
The line on a distance time graph can go in any direction.
The line may be horizontal, time changing without a change in distance, but it can not be vertical. That would be a change in distance without a change in time. Additionally, our line cannot go backwards; time is always moving forwards.
Keywords
Rate of change - The rate of change is how quickly one variable changes in relation to another.
Gradient - The gradient is a measure of how steep a line is, calculated by finding the rate of change in the $$y$$-direction with respect to the positive $$x$$-direction.
