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

• 1. Plot a distance - time graph as shown above.

  2. Join up the points with straight lines.

  3. Calculate the speed in each section. For the above you would do 0-4 seconds, 4-7 and 7-10.

  4. Where have they stopped?

  5. Estimate the speed at 3.7s. Why is this only an estimate?
