用3DMAX模拟平抛物体运动轨迹

Simulating the Trace of a Moving projectile

从一个物理演示动画的制作过程的叙述开始，了解物理演示动画制作的最基本的过程及步骤，并介绍了物理演示动画的特点和相应处理方法．

From the description of the process of making a moving picture for displaying experiments, we can learn the basic process of making moving pictures and the features for displaying physics experiments and processing method. We hope this method will play a leading and introductory role in displaying of physics experiments.
