论文摘要
将几个硬球放入二维碗中可以形成非常基本的硬球系统二维模型。当二维碗在中心周围以均匀速度的平行旋转时，当球数很小时，小球在二维碗中的运动方向与二维碗的运动方向一致。但是，当我们一一增加球的数量时，两者似乎会显示相反的运动趋势。我们通过物理建模全面分析了这个问题，并激发读者思考模型对分析复杂物理问题的重要性。最后，由于本文涉及知识的许多方面，因此大学物理教师可以选择整个问题或将其引入课堂的一部分问题。
Putting several hard balls into a two-dimensional bowl can form a very basic two-dimensional model of hard-ball system. When the two-dimensional bowl has a parallel-rotation at a uniform speed around a center, when the number of balls is small, the direction of motion of the small balls in the two-dimensional bowl is consistent with that of the two-dimensional bowl; However, when we increase the number of balls one by one, the two will seem to show the opposite movement trend. We analyze this problem comprehensively through physical modeling and inspire readers to think about the significance of the model for analyzing complex physical problems. Finally, because this article involves many aspects of knowledge, college physics teachers can choose the whole problem or part of the problem to introduce it into the classroom.
