基于Matlab的小球自由落体仿真实现

Simulation of Ball Free Falling Body Based on Matlab

利用Matlab仿真了小球自由落体运动,并实现小球自由落体运动的动画演示。该方法首先根据高中物理中自由落体运动知识设置小球下落时的高度、初速度、加速度等参数;并由Matlab函数绘制小球自由落体的每一帧图片以及每一帧图片上小球的位置、颜色等;最后将图片合成出小球自由落体运动视频。仿真实验结果验证了小球自由落体运动与物理自由落体原理的一致性。该动画演示视频便于理解自由落体运动知识,增强学习MATLAB程序编写的兴趣。

In this paper,the free falling body movement of small ball is simulated through utilizing Matlab,and the video of ball free falling body movement is realized. Firstly,the parameters of the free fall small ball according to the high school physics knowledge are set,for example drop height,initial velocity,acceleration and so on. And then the ball position and color of each frame picture is draw on each picture. Finally,the motion video of ball free fall is synthesized. The simulation results verify the consistency of the free falling body movement and the physical free falling body principle. The video is easy to understand free falling body movement knowledge and it may enhance the interest of learning Matlab program.
