摘要
利用视频播放软件和Excel数据处理软件,分析了自由落体运动,直观地演示了物体下落的加速过程,并通过极限法分析和Excel软件处理实验数据,在较少帧数内得到了准确的加速度值,从而逐步建立自由落体运动的相关概念,启发学生的科学思维.
Using video player and Excel data processing software, the motion of a free falling body was video recorded directly and analyzed. The accurate acceleration value was obtained within a few frames of the video, then the concept of free falling body was established gradually, which contributed to inspire the students' scientific thinking.
