高中物理教师在授课“平抛物体运动”一节时,为说明平抛物体在水平方向是匀速直线运动和竖直方向是自由落体运动,想尽各种方法改进实验器材和实验的条件,取得了一定的效果.但更精细的研究平抛运动的方法是频闪照相,可中学的实验条件,无法用频闪照相完成平抛运动的频闪照片.最近
When the high school physics teacher teaches the “Plane-Planting Object Movement” section, in order to illustrate that the paraboloid object is a uniform linear motion in the horizontal direction and a free-fall motion in the vertical direction, he has tried various methods to improve experimental equipment and experimental conditions. A certain amount of effect. But a more intensive method for studying flat throwing motion is stroboscopic photography, which can be experimental conditions for middle school students. It is impossible to complete stroboscopic photos of flat throwing motions with stroboscopic photography. Recently
