[0002] In the teaching process of middle school physics, in order for students to better and more intuitively understand the acceleration data, it is necessary to demonstrate the simulated free fall movement to students. In the free fall experiment, special equipment is needed to support it, but the traditional free fall experiment simulation device exists. Many problems, complex structure, inconvenient use and adjustment, insufficient fixation, and difficult to guarantee the balance, resulting in the accuracy of the simulation test to be questioned, which brought great trouble to the user, and it is impossible to adjust the landing ground according to the demand. Adjustment of the horizontal angle with the placement surface makes it difficult to adjust the height of the falling point, the accuracy of the experimental data is difficult to be guaranteed, it is not convenient to release the falling ball, the timing is not accurate enough, and the cut-off time lags behind when touching the ground, which virtually increases the teacher's teaching The burden reduces the accuracy of the simulation test, resulting in low efficiency of the free fall experiment simulator, so it is imperative to realize a high school physics free fall experiment simulator that can solve such problems
