Draw distance-time graphs for rest, uniform speed, increasing speed, and decreasing speed.

  • Rest: The distance-time graph will be a horizontal line because the distance remains constant over time.
  • Uniform Speed: The distance-time graph will be a straight line with a constant positive slope.
  • Increasing Speed: The distance-time graph will be a curve that gets steeper as time progresses.
  • Decreasing Speed: The distance-time graph will be a curve that becomes less steep as time progresses.
