Distance time graphs

• What does a distance-time graph represent?

  Distance travelled over time
• What does a flat section on a distance-time graph indicate?

  The object is stationary
• What does a straight uphill line on a distance-time graph represent?

  The object is travelling at a steady speed
• What does a steepening curve on a distance-time graph indicate?

  The object is speeding up
• What does a curve that flattens out on a distance-time graph indicate?

  The object is decelerating
• How can you find the speed of an object at a specific point on a distance-time graph?

  By finding the gradient of the curve at that point of the tangent to the curve at that
• What does the gradient of a distance-time graph represent?

  Speed of the object
• What does a steeper graph on a distance-time graph indicate?

  The faster the object is moving
• What does a curve on a distance-time graph indicate?

  Acceleration or deceleration of the object
• What does a downward slope on a distance-time graph indicate?

  The object is deaccelerating
• What is indicated by a horizontal line on a distance-time graph?

  The object is not moving
• What can you infer if the distance-time graph shows a series of steep and flat sections?

  The object is alternating between speeding up and stopping
• What does the term "decelerating" mean in the context of a distance-time graph?

  The object is slowing down
• What does the term "accelerating" mean in the context of a distance-time graph?

  The object is speeding up or slowing down.
• How does the gradient of a distance-time graph relate to speed?

  The steeper gradient indicates a higher speed
• What does "steady speed" mean in the context of a distance-time graph?

  The object maintains a constant speed
