通过matlab编写了物理实验中弹性球的实验，演示了弹力球由于受到重力作用弹跳高度逐渐减少的过程， 能够仿真实验全程能够真实再现整个实验过程。-Through MATLAB elastic sphere in experimental physics experiments that demonstrate the ball bounces due to subject to the force of gravity jumping height gradually decreased to simulation the whole experiment can reappear throughout the experiment.
