| Abstract: | We improve the simple pendulum of the traditional experiment instructments mainly by measuring the vibraion period of the pendulum using a digital timer and a photoelectric gate circuit and controlling the pendulum ball with electromagnet so that the ball will only move within the vertical plane.With these measures,time spent on experiment is saved,the efficiency of the experiement is improved and the accuracy of the experiemental results are raised. |
