There are 4 possible shapes to a Distance-Time graph:
Time is the __________ variable and so is plotted on the __________ axis, Distance is the __________ variable and is plotted on the __________ axis. The gradient of a graph is the change in y divided by the change in x. So for a distance time graph the gradient equals the change of distance divided by the change in time which is __________.
This means the steeper the line (the higher the gradient) the __________ the object is travelling.
If we plot __________ instead of distance then we can have a negative gradient, which shows that the object has moved __________.
