Distance does not involve direction. Distance is a scalar quantity. Displacement includes both the distance an object moves, measured in a straight line from the start point to the finish point and the direction of that straight line. Displacement is a vector quantity. Speed does not involve direction. Speed is a scalar quantity. The velocity of an object is its speed in a given direction. Velocity is a vector quantity. Define distance. Define displacement. Explain the difference between distance and displacement. Explain the difference between scalars and vectors and state which distance and displacement are. 1 Analyse both a 100 m race and a 400 m (one an oval track) race. Look at how the distance and displacement changes for each race. Discussion questions: What is the difference between distance and displacement? If I complete a complete lap of a 400 m have I gone anywhere? Investigate how the distance travelled by a person and displacement is usually different. This can be done by a modelling activity. For example, students walk 4 m in a straight line and then turn left and walk a further 5 m. What distance have they moved and what is their displacement? This can be done both mathematically and by taking direct measurements.
