高考涉及弹簧问题的题型多样,主要围绕弹簧弹力的大小、弹性势能与弹力做功的关系展开,与其它知识如物体平衡、牛顿运动定律、动能定理、机械能守恒定律、功能关系等综合.问题的呈现方式有陈述性的,也有探究性的.高考中相关弹簧模型的知识点有:1.一般为轻弹簧.发生形变时(设形变量为x),弹簧对其两端物体的弹力大小相等、方向相反,沿弹簧的中轴线方向.在弹性限度内,其弹力的大小遵循
There are many kinds of questions about spring problems in the college entrance examination, which mainly focus on the relationship between spring elastic force, elastic potential energy and elastic work, and other knowledge such as object balance, Newton’s law of motion, kinetic energy theorem, conservation law of mechanical energy and functional relationship. Presented in a declarative, but also exploratory.Examination of relevant spring model in the college entrance examination knowledge points are: 1.General for the light spring.Deformation (set deformation variable x), the spring on both ends of the object of equal elastic size , In the opposite direction, along the central axis of the spring in the elastic limit, the size of its elastic follow
