高中物理对于某些较难求解的问题 ,若能与数学图形相结合 ,按数形结合的思想分析处理 ,解题过程将大大简化 ,物理计算可快速便捷 .现在就用数形结合的思想处理竖直上抛 .竖直上抛的基本公式是 s=v0 t- 12 gt2 ,位移是时间 t的二次函数 ,其图像是抛物线 ,如图 1所示 ,其最大值就
High school physics for some of the more difficult to solve the problem, if combined with the mathematical graphics, according to the number of ideas combined analysis and processing, the problem-solving process will be greatly simplified, physical computing can be fast and convenient. Now use the idea of combination of numbers and shapes Deal with the vertical throw. The basic formula for throwing up vertically is s=v0 t- 12 gt2. The displacement is a quadratic function of time t. The image is a parabola. As shown in Figure 1, the maximum value is
