| 摘 要： | 针对一般文献中将空气阻力与地球自转分开来处理抛体运动存在误差大的问题,本文同时考虑空气阻力与地球自转的影响,结合不同的空气阻力模型建立了相应的抛体运动微分方程。忽略二阶小量,解微分方程,依次得到抛体的运动规律,最后利用Mathematic编程作出了抛体的位移—时间图像。

| Abstract: | As the movement of projectile takes place,we consider air resistance and Earth's rotation simultaneously in this paper while consider them separately in general literatures in which there exist some great errors.Also,combined with diffierent air resistance models,we establish its corresponding differential equation.Approximate solutions to these equations are given by ignoring a small amount of second-order,so the movement laws of projectile are obtained.In the end projectile's displacement-time images are drawn with the aid of Mathematica programming. |
