Show transcript
The instantaneous speed of an object is the speed at a particular moment in time.
For an accurate measurement a person needs to be in line with the observation.
Manual timing can lead to a range of timing errors.
Repeat readings can reduce the effect of random errors.
Some readings are anomalous and these should not be used in caluations of averages.
