随着办学条件的不断完善,摄、录像机在学校中日渐普及,充分发挥摄像机的特点,将其应用于实验教学。能收到十分满意的效果。下面谨向大家介绍两个物理实验,希望能起到抛砖引玉的作用。一、平抛竖落实验:用传统的方法实验,一般只能证明平抛物体在竖直方向上作自由落体运动,至于水平方向上的运动情况,还需要借助于课本上的闪光照片。本人在整张的绘图纸上画满一平方分米的方格,把它帖在绘图板上,使它作背景,用摄像机拍摄平抛竖落的实验过程。之后,再利用录像机步进放像功能(有穿梭放
With the continuous improvement of school conditions, cameras and video recorders are becoming increasingly popular in schools, giving full play to the characteristics of cameras and applying them to experimental teaching. Can receive very satisfactory results. I would like to introduce to you two physics experiments. I hope that I can play a role in this. First, flat throw vertical fall experiment: the use of traditional methods of experimentation, generally can only prove that the flat parabolic objects in the vertical direction for free-fall motion, as for the horizontal direction of the movement, but also need to rely on the textbook flash photos. I painted a square decimetre square on the entire drawing paper, put it on the drawing board, made it a background, and shot the experiment process with a camera. After that, use video recorder to step playback function (with shuttle
