Document Summary
Weight is the amount of force due to gravity that object experiences. Newton n unit of mass in the us. Accuracy is how close a measured value is to its. Precision is how close the values of measurements of the quantity are to each other true value repeated. Systematic errors cause measurements to deviate from the true value in a regular predictable way theyaffect the accuracy of the measurement. Random error remain after all possible systematic errors have been excluded sometimes called noise they lower the precision the deviations that possibly the accuracy ofthe measurement. Repeated measurements of variation uncertainty to determine the amount. Calibration of measuring instruments accuracy of is testing the precision instruments to known standards. Varying conditions to detect systematic errors calibration the measuring. You must have high precision to havehigh probability of accuracy. Random errors introduce uncertainty into measured valves ex.
