We analyze an example of a totally inelastic interaction between two spinning objects from a didactic perspective. We first describe an interpretative model highlighting why a part of the initial rotational energy needs to be dissipated; this point can be visualized in a diagram of capacitive characteristic curves. Subsequently, we propose and discuss a concrete novel experiment, in which an inductive coupling between two spinning objects is realized. A detailed energy analysis and an introduction to dynamical modeling complete the proposed didactical approach.

通过电感耦合的旋转碰撞

我们从教学的角度分析了两个旋转物体之间完全非弹性相互作用的例子。我们首先描述了一个解释模型，强调了为什么需要耗散一部分初始旋转能量；这一点可以在电容特性曲线图中可视化。随后，我们提出并讨论了一个具体的新颖实验，其中实现了两个旋转物体之间的感应耦合。详细的能量分析和对动力学建模的介绍完善了建议的教学方法。
