| Abstract: | In this paper, firstly, the method of evaluation ot uncertainty on me alreet ana ments was introduced in detail. Then the traditional period formula of the simple pendulum was carefully deduced. According to our teaching practice of the uncertainty in many years, the processing of applying the uncertainty theory to the experiment of measuring acceleration of gravity by the simple pendulum was also illustrated based on our actual experimental data. At last, a detailed analysis of uncertainty for our measuring results in teaching was presented. It is not only beneficial to understand and master the method of processing experimental data but also to better improve students enthusiasm and initiative for universi ty physics experiment. |
