在教材中,圆锥摆问题作为向心力公式的探究专门以实验方式呈现,足见该模型的重要性,这种重要性多次在高考中体现,所以构建模型思想解决更多的问题是本文的意图,期望抛砖引玉,引发读者更多的思考.【题源示例】如图1所示,一个内壁光滑的圆锥筒的轴线垂直于水平面,圆锥筒固定不动,有两个质量相同的小球A和B紧贴着内壁分别在图中所示的水平面内做匀速圆周运动,则下列说
In the textbook, the conical pendulum problem is presented experimentally as a probe of the centripetal force formula, which shows the importance of the model. This importance has been reflected in the college entrance examination many times. Therefore, it is the intention of this article to construct more model questions to solve more problems. Expected to initiate, lead readers to think more. [Source sample] As shown in Figure 1, an inner wall of a smooth cone axis perpendicular to the horizontal plane, the cone fixed, there are two equal mass of pellets A and B Close to the inner wall in the figure shown in the horizontal plane to do uniform circular motion, the following said
