该设计基于牛顿摆的工作原理，它的特点是把若干个大小相同的金属球并排地悬挂在一起，并使这些金属球相互之间非常勉强地相互接触。
The design is based on the Newton's cradle, which features several identically sized metal balls suspended so that the balls barely touch each other.
利用物理仿真实验室软件对非对心碰撞、超弹性碰撞、牛顿摆等碰撞实验进行了模拟和分析，为碰撞问题的研究和教学提供了有效的方法。
In this article, non-central collision, superball and Newton′s cradle are analyzed with the virtual experiment which is a useful way of collision′s analyzing and teaching.
