In college physics, you write a laboratory report for each experiment that contains the essential any significant experimental errors or uncertainties. Random errors are errors which fluctuate from one measurement to the next they yield results distributed about some mean value they can occur for a variety of reasons. Gravity can be used to teach experimental design to advanced physics students this involves the estimation of uncertainties in measurement and in the values of quantities derived from them.
