Learning intentions:
> what do we already know about speed, acceleration and forces?
> how can we measure speed?
> what is speed and how can we visualise it?
Activity: Take the pre-topic quiz. This is not an assessment, just a way of checking at the start of a topic what people already know. At the end of the topic if we re-take the same quiz so we can check our progress.
Investigation: walking speed. Follow the instructions on the practical sheet to carry out a simple investigation into speed, its units and how to calculate it.
Can you:
> make careful measurements
> calculate speeds from your results
> explain what makes measurements more accurate
