摘要

最近的两次月球着陆器任务都在着陆时发生了倾覆。我们分析了一个简化模型，以确定导致倾覆的物体的横向速度，以此作为保持角动量的非弹性碰撞的实际例子。解决方案采用了力学入门课程中涉及的旋转动力学和守恒定律。我们建议进一步研究，包括可在教学实验室进行的简单实验。

Tripping on the Moon

Two recent lunar lander missions have toppled over on touchdown. We analyse a simplified model to determine the lateral speed of an object that results in tipping, as a practical example of an inelastic collision that conserves angular momentum. The solution employs rotational dynamics and conservation laws covered in an introductory mechanics course. We suggest further investigations, including simple experiments that can be performed in the teaching laboratory.

期刊介绍： Physics Education seeks to serve the physics teaching community and we welcome contributions from teachers. We seek to support the teaching of physics to students aged 11 up to introductory undergraduate level. We aim to provide professional development and support for teachers of physics around the world by providing: a forum for practising teachers to make an active contribution to the physics teaching community; knowledge updates in physics, educational research and relevant wider curriculum developments; and strategies for teaching and classroom management that will engage and motivate students.
