Understand it, don't just memorise it

Short interactive lessons: you drive the car, play the graphs and spot the patterns yourself — then we name the physics and you try exam questions on it.

  1. 1Graphs tell storiesRead a displacement–time graph like a story: where is it, and which way is it going? 8 min
  2. 2Steepness is speedTilt a line and feel the car speed up: the gradient of a D–T graph is the velocity. 10 min
  3. 3Distance vs displacementThe odometer counts every metre; displacement only cares where you end up. 9 min
  4. 4Curves: changing speedA curved D–T graph means the velocity is changing: steeper is faster, flatter is slower. 8 min
  5. 5Reading velocity–time graphsNow the height of the line is the velocity — and a flat line no longer means stopped. 9 min
  6. 6Speeding up or slowing down?Acceleration is the gradient of a V–T graph — and its sign alone doesn't tell you if you're speeding up. 10 min
  7. 7Area is displacementVelocity × time = metres: the area under a V–T graph is how far the object has moved — with a sign. 11 min
  8. 8Connect the two graphsSlope of D–T = height of V–T. Area of V–T = rise of D–T. Then describe it like a physicist. 12 min
