02. Distance-time graphs
Learning intentions:
How a distance-time graph can tell us if an object is stationary or moving at constant speed
What the gradient of the line on a distance time graph can tell us
How to use the equation for constant speed

Plot a distance - time graph as shown above.
Join up the points with straight lines.
Calculate the speed in each section. For the above you would do 0-4 seconds, 4-7 and 7-10.
Where have they stopped?
Estimate the speed at 3.7s. Why is this only an estimate?
