锥体上滚实验是一种常见的科普演示实验，然而对其原理的分析多停留在定性或半定量阶段．建立基于实物的模型并分析其原理，是物理学科的关键能力和核心素养．本文以“锥体上滚”实验为例，结合《大学物理》及《理论力学》课程内容，通过建立坐标系，求解质心运动轨迹方程，深入分析锥体上滚的条件．同时，进一步推导出锥体在“上滚”过程中质心的速度，并探讨了锥体“只滚不滑”的条件以及锥体与倾斜轨道接触点的位置．通过运用理论知识解决实际问题，旨在提升学生的物理学科关键能力．

The double cone rolling uphill experiment is a common science demonstration experiment. However, its principle analysis often remains at a qualitative or semi-quantitative stage. Building a model based on physical objects and analyzing its principles is a key capability and core literacy of the physics discipline. This article takes the double cone rolling uphill experiment as an example, based on the content of University Physics and Theoretical Mechanics courses. By establishing a coordinate system, solving the equation of the center of mass motion trajectory, and analyzing the conditions for the cone to roll up. Additionally, it further derives the speed of the center of mass during the double cone rolling uphill process, discusses the conditions for rolling without slipping, and the position of the contact point between the cone and the inclined track. By using theoretical knowledge to solve practical problems, students′ key capabilities in physics are improved.
