| Abstract: | As an important link in the experiments of university physics ,the calculation of uncertainty is relatively complicated. Methods of calculating uncertainty differ from one another in various reference books on physical experiments. The authors of this paper,with the experiment of the measurement of rotary inertia as the example, summarize a set of simplified formula for the calculation of uncertainty. The application of this simplified formula,which is conducive for the students to calculate the measurement of uncertainty, greatly simplifies the uncertainty calculations in the physics experiment. |
