“几何画板”软件是非常优秀的工具软件,具有操作简单的特点,能把计算结果快速、准确地用图像的方式形象、直观地描绘出来.它可以直接用来解决一些中学生运用所学的数学知识不能解决的问题,还可以帮助中学生处理一些运用数学知识定量运算有困难的问题.下面笔者举例说明几何画板在解决物理疑难问题中的应用.例1 在圆形区域里有一个匀强磁场,方向如图1示,有一束速率各不相同的质子自 A
“Geometric Sketchpad” software is a very good tool software, has the characteristics of simple operation, can quickly and accurately use the image to visually and accurately describe the calculation results. It can be directly used to solve some middle school students to use the learned The mathematics knowledge can not solve the problem, but also can help middle school students to deal with some problems with the use of mathematics knowledge quantitative calculation difficult. Here the author illustrates the application of geometric drawing board in solving physical problems. Example 1 There is a uniform in the circular area The magnetic field, as shown in Figure 1, shows a beam of protons with different speeds.
