record the time it takes for a toy car to travel a measured distance, plot on a distance-time graph. (e.g. the toy car takes 10 seconds to travel 4 metres). repeat at different speeds and plot graphs. compare results.
tennis ball:
record the time it takes a tennis ball to be thrown 10m, repeat 10 throws from the same person (to make it a fair test, as some people will throw faster/slower). Plot results on a graph.
