贵刊在2010年第1期上,对2009年高考江苏卷第9题作了解答分析,文中解答多是定性分析,读后有意犹未尽之感.就第9题来说,设问角度新颖,对考生的思维能力以及数学推理运算能力都有很高要求,主要体现在:第一,物理情景比较复杂,两物块均是在变力作用下运动,对物体的运动情况难有一个准确认识;第二,两物块之间有弹簧连接,相互影响,物理量间的关系比较复杂,定量关系确定有困难;第三,涉及运动都为非匀变速运动,建立数学模型求解不容易.下面对该题进行解答,并对题中所给条件作拓展性讨论.
Your first issue in 2010 on the 2009 college entrance examination in Jiangsu volume 9 questions for analysis, the answer is mostly qualitative analysis, after reading deliberately do not feel .About the 9th question, set the point of view novel, There are high demands on the examinee’s thinking ability and math reasoning ability, mainly reflected in: First, the physical situation is more complex, both are moving under the force of change, it is difficult to have an accurate understanding of the movement of the object ; Second, there is a spring connection between the two blocks, which affects each other. The relationship between the physical quantities is rather complicated, and it is difficult to determine the quantitative relationship. Thirdly, it is not easy to set up the mathematical model to solve the problem that non-uniform speed motion is involved in the movement. Answer the question and expand the discussion on the conditions given in the question.
