Speed & Distance-Time Graphs

Science · Forces & Motion · conceptual

Calculate average speed using the equation speed = distance ÷ time, represent journeys on distance-time graphs, and interpret gradient as speed and flat sections as stationary periods

What mastery looks like

  • Uses speed = distance ÷ time to calculate average speed with correct units (m/s, km/h)
  • Draws a distance-time graph for a given journey with correct axes and labels
  • Reads a distance-time graph to determine speed, stopping points, and direction of travel
  • Identifies which section of a distance-time graph represents the fastest speed

Check your understanding

If Speed & Distance-Time Graphs tracked a cycle ride on a map and knew how far they went and how long it took, could they calculate the average speed — and then sketch a rough graph showing the journey including a stop for lunch?
