安徽高考理综(物理部分)试题及解析(Word版)
高中物理学习材料(马鸣风萧萧**整理制作)2009年高考安徽卷理科综合能力测试物理部分试题全解全析【试卷总评】今年是安徽省实现新课程的首次高考,今年理综物理卷紧扣课程标准,严格遵循2009年安徽省高考考试说明,从传统的高考到新课程背景下的首次高考过渡平稳,既体现了我省中学物理教学的实际状况,又体现了新课程的理念。
试题覆盖面广,在着重考查考试说明中的主干知识的同时,又考查了考生的推理能力、分析综合能力、实验能力、探究能力、应用数学知识处理物理问题的能力。
今年的理科综合中的物理分值为110分,08年为120分。
题型与08年相同,为选择题、实验题和计算题。
选择题7题,共42分,比08年减少一题,分值少6分;实验题和08年相似均为力学实验和电学实验,共18分;计算题和08年相同均为3题,但分值比08年少4分。
难度比08年有所下降,考查知识点比08年少(见下表)。
今年的理综试题主要体现了以下几点:一、重视基础知识的考查(受力分析、牛顿运动定律、动能定理);二、立足课本,如第21题实验题,既考虑到我省不同层次中学物理实验教学条件的实际情况,又体现了考查考生实验动手能力、探究学习能力的精神。
三道实验题的素材、情境均来源于课本,但考查的角度、设问的方式又区别于课本,只有亲自做实验的考生才能正确作答,对中学物理实验教学有着很好的导向作用;三、题目新颖,体现时代特征,如第14题的洁净能源、第15题的卫星碰撞、第16题的大爆炸理论、第17题的智能化电动扶梯、第22题的残奥会、第24题的过山车等,在考查考生基本知识和基本技能的同时,注意理论联系实际,注意科学技术和社会、经济发展、生活等方面的广泛应用;四、试题既有利于促进中学物理教学又有利于各类高校选拔人才。
如第16题,考查了考生的知识迁移能力;第20题在考查考生分析、综合能力的同时,又考查了考生的空间想象能力。
第24题作为压轴题,试题层次分明、难度递进,具有较好的区分度,对考生缜密、细致思考问题的能力有一定的要求。

(4)分析 图像。如果 图像是一条直线,表明∝ ;如果不是直线,可考虑是否存在 ∝ 、 ∝ 、 ∝ 等关系。
.答案:
(1)3,0.6,1,0~10。(2)由于电压表的分流作用造成电流表读数总是比电池实际输出电流小。
解析:由于电源是一节干电池(1.5V),所选量程为3V的电压表;估算电流时,考虑到干电池的内阻一般几Ω左右,加上保护电阻,最大电流在0.5A左右,所以选量程为0.6A的电流表;由于电池内阻很小,所以保护电阻不宜太大,否则会使得电流表、电压表取值范围小,造成的误差大;滑动变阻器的最大阻值一般比电池内阻大几倍就好了,取0~10Ω能很好地控制电路中的电流和电压,若取0~100Ω会出现开始几乎不变最后突然变化的现象。
