针对某些高中物理资料上两例关于物体最大速度问题的错误解答进行剖析,根据物体速度的定量表达式,应用Maple软件,将物体速度的变化情况用图象直观地表示出来,并用导数知识和数值计算法解得物体速度最大的位置及速度最大值的比较精确的结果。
According to the quantitative analysis of the object velocity, two examples of the wrong answers about the maximum velocity of the object in some high school physics data are analyzed. With Maple software, the change of the object velocity is visually represented by the image and the derivative knowledge The numerical method solves the more accurate result of the maximum velocity of the object and the maximum velocity.
