轻弹簧是一种理想化的物理模型,以轻质弹簧为载体,设置复杂的物理情景。重点考查力的概念、物体的平衡、牛顿定律的应用及能的转化与守恒。此类命题是物理高考命题中的重点,几乎每年高考卷面均有所见,应引起足够重视。本文就其中的三类问题进行解析如下: The light spring is an idealized physical model, with light springs as the carrier to set up complex physical scenarios. Focus on the concept of force, the balance of objects, the application of Newton’s law, and the transformation and conservation of energy. Such propositions are the key points in the physics college entrance examination propositions. Almost every year in the college entrance examination enthusiasm is seen, and should be given enough attention. This article analyzes three of the following issues:
