| Abstract: | In the experiment of measuring the gravity acceleration, through the improved ex- perimental design, we eliminated the metrical errors of the pendulum length and the swing pe- riod brought from the sensor triggers and the fixed end of cycloid. Video and some software such as Vegas and Origin were used to measure and analyze the swing state. Experimental re- sults indicated that the improved experimental design reduced the introduction of errors and improved the accuracy of the experimental measurements. |
