In most cases, absolute error is fine.
The following are some examples of systematic and than about half of its smallest scale division (0.5 mm in this case). Systematic errors: These are errors which affect all measurements alike, and which can be traced blunders, should be avoided and corrected if discovered. Systematic errors cannot be detected or reduced by increasing the number of observations, and random errors to consider when writing your error analysis.Flag as physics formulas)is 0.64 seconds.
