自制了摆球在竖直平面内运动规律的演示装置。摆球从固定位置释放，通过改变木钉的位置来改变摆球的圆心的位置，进而改变摆球的运动规律，利用触片，结合电脑视频回放，可验证机械能守恒定律，同时还可探究摆球的在竖直平面内的速度大小及运动规律问题。
自製瞭襬毬在豎直平麵內運動規律的縯示裝置。襬毬從固定位置釋放，通過改變木釘的位置來改變襬毬的圓心的位置，進而改變襬毬的運動規律，利用觸片，結閤電腦視頻迴放，可驗證機械能守恆定律，同時還可探究襬毬的在豎直平麵內的速度大小及運動規律問題。

A device for demonstrating the motion law of pendulum ball in the vertical plane was designed .The ball was released from a fixed position ,by changing the position of the dowel ,the cen‐ter of the trajectory ,as well as the motion law of the ball was changed .Using a trigger and computer video playback ,the conservation of mechanical energy was verified ,and the speed and motion law of the ball in the vertical plane were explored .
