10年来 ,全国高考物理试卷中的弹簧试题频频出现 ,引起了广大物理教师的高度重视 .弹簧试题之所以多年来深受物理命题专家的青睐 ,我们认为 :首先是由于弹簧本身的特性与其相连物体构成的系统的运动状态具有很强的综合性和隐蔽性 ;其二是弹簧在伸缩过程中涉及的力和加速度、功 In the past 10 years, the spring examination questions in the national college entrance examination physics papers have frequently appeared, which has caused the physics teachers to attach great importance. The spring test questions have been favored by physical proposition experts for many years. We believe that the first is the characteristics of springs and their associated objects. The motion state of the system is very comprehensive and concealed; the second is the force and acceleration involved in the expansion and contraction of the spring.
