Many students have only an intuitive idea of speed and cannot relate it to information on distance and time

Forces and Motion


Diagnostic Resources

The following questions all probe pupils’ understanding of the idea of speed, and are intended to be used in combination to explore understanding of this idea in some depth.

For more information, see the University of York EPSE website.

Resources to Address This

  • Increasing and Constant Speeds (5-11)

  • What speed?  (11 - 14)

    Source - SPT/Mo01TA03

    A circus of activities for measuring the average speed of different objects.  The purpose of this activity is for pupils to take measurements and to practise using the relationship: speed = distance / duration

  • Ticker-timers for investigating speed (14 - 16)

    Source- Practical physics/ Force and Motion/ Time, distance and speed/ ...

    Making ticker-timer charts can develop an understanding of speed-time graphs.  The activity involves measuring distances and times.
