inside the graph.

Build a journey, watch it unfold and connect every change in motion to distance–time and speed–time evidence.

Investigation 1

Build and analyse a journey

Use speed = distance ÷ time, interpret gradients and find distance from area under a speed–time graph.
Time0.0 s
Distance0.0 m
Displacement0.0 m
Speed0.0 m/s
Velocity0.0 m/s
Journey track

Distance–time · gradient = speed

Speed–time · area = distance

Investigation 2

Distance is not displacement

Compare total path length with the straight-line vector from start to finish.
Two-dimensional journey
Investigation 3

Graph interpretation studio

Identify rest, constant speed, acceleration and deceleration; calculate gradient and area.

Learning objectives

  1. Compare distance and displacement.
  2. Use speed = distance ÷ time.
  3. Define velocity as speed in a stated direction.
  4. Use average speed = total distance ÷ total time.
  5. Interpret distance–time and speed–time graphs.
  6. Recognise rest, constant speed, acceleration and deceleration.
  7. Calculate speed from d–t gradient.
  8. Calculate distance from area under a speed–time graph.
