近几年的物理高考,弹簧在试题中的运用屡见不鲜.弹簧伸缩所产生的弹力大小、方向及相连物的运动状态都具有综合性,可提供多变的思维空间;弹簧的伸缩过程包含功、能、冲量、动量以及相连的热学中气体状态参量的变化,给运用动能定理、动量定理、动量守恒、机械能守恒、气体定律等提供了较广阔的天地,是考查学生“对物理过程的分析”,和“物理思维品质及其清晰程度,能反映学生学习潜能和分析、解决问题的能力”.
In recent years, the physical entrance exam, the use of springs in test questions is not uncommon. The elastic force produced by the spring stretching, the direction and the connected state of movement are comprehensive, can provide a variety of thinking space; spring stretching process includes work, The changes in energy, momentum, momentum, and connected gas state parameters in thermal sciences provide a broader world for the use of kinetic energy theorems, momentum theorems, conservation of momentum, conservation of mechanical energy, and gas laws. It is an examination of students’ “analysis of physical processes”. , And “The quality of physical thinking and its clarity, can reflect students’ learning potential and ability to analyze and solve problems.”
