中考物理易错知识点汇总 1. 密度不是一定不变的。密度是物质的属性，和质量体积无关，但和温度有关，尤其是气体密度跟随温度的变化比较明显。 2. 天平读数时，游码要看左侧，移动游码相当于在天平右盘中加减砝码。 3. 匀速直线运动的速度一定不变。只要是匀速直线运动，则速度一定是一个定值。 4. 平均速度只能是总路程除以总时间。求某段路上的平均速度，不是速度的平均值，只能是总路程除以这段路程上花费的所有时间，包含中间停的时间。 5. 受力分析的步骤：确定研究对象；找重力；找接触物体；判断和接触物体之间是否有压力、支持力、摩擦力、拉力等其它力。 6. 平衡力和相互作用力的区别：平衡力作用在一个物体上，相互作用力作用在两个物体上。 7. 物体运动状态改变一定受到了力，受力不一定改变运动状态。力是改变物体运动状态的原因。受力也包含受平衡力，此时运动状态就不变。 8. 惯性大小和速度无关。惯性大小跟质量有关。速度越大只能说明物体动能大，能够做的功越多，并不是惯性越大。 9. 惯性是属性不是力。不能说受到惯性，只能说具有惯性。
10. 物体受平衡力?物体处于平衡状态（静止或匀速直线运动）。这两个可以相互推导。物体受非平衡力：若合力和运动方向一致，物体做加速运动，反之，做减速运动。 11. 1Kg≠9.8N。两个不同的物理量只能用公式进行变换。 12. 月球上弹簧测力计、天平都可以使用，太空失重状态下天平不能使用而弹簧测力计还可以测拉力等除重力以外的其它力。 13. 压力增大摩擦力不一定增大。滑动摩擦力跟压力有关，但静摩擦力跟压力无关，只跟和它平衡的力有关。 14. 两个物体接触不一定发生力的作用。还要看有没有挤压，相对运动等条件。 15. 摩擦力和接触面的粗糙程度有关，压强和接触面积的大小有关。 16. 杠杆调平：左高左调；天平调平：指针偏左右调。两侧的平衡螺母调节方向一样。 17. 动滑轮不一定省一半力。只有沿竖直或水平方向拉，才能省一半力。 18. 画力臂的方法：一找支点（杠杆上固定不动的点），二画力的作用线（把力延长或反向延长），三连距离（过支点，做力的作用线的垂线）、四标字母。 19. 动力最小，力臂应该最大。力臂最大做法：在杠杆上找一点，使这一点到支点的距离最远。

一、初中物理电路类问题 1．图甲是身高、体重测量仪，当体检者站在台面上时，能自动显示身高和体重．电路原理如图乙所示,电压表、电流表分别显示身高和体重的大小,压敏电阻R 的阻值随压力增大而增大,滑片P 随身高增高而上滑．下列分析正确的是（） A．身高越高电压表示数大B．身高越高通过R0流越小 C．体重越大电流表示数越大D．体重越大压敏电阻两端电压越小 【答案】A 【解析】 【分析】 【详解】 AB．由电路图可知，R与R0并联，电压表测滑片P下方电阻丝两端的电压，电流表测压敏电阻R支路的电流，因电压表的内阻很大、在电路中相当于断路，所以，人的身高变化即滑片移动时，R0接入电路中的电阻不变，因并联电路中各支路两端的电压相等，且各支路 独立工作、互不影响，所以，由I=U R 可知，通过R0的电流不变，故B错误；当身高越高 时，滑片上移，滑片P下方电阻丝的阻值变大，由U=IR可知，滑片P下方电阻丝两端的电压变大，即电压表的示数变大，故A正确； C D．当体重越大时，压敏电阻受到的压力越大，由压敏电阻R的阻值随压力增大而增大可 知，R的阻值越大，由I=U R 可知，通过R的电流越小，即电流表的示数越小，故C错误； 压敏电阻R两端的电压不变，仍等于电源电压，故D错误． 2．如图所示，电源电压为6V且保持不变，定值电阻R1标有“10 Ω 0.4A”字样；R2为电阻箱（阻值范围0～999Ω，允许通过的最大电流为1A）；电流表量程为0～0.6A，电压表量程为0～3V。闭合开关S，调节电阻箱，在保证电路安全的情况下，则下列说法正确的是（）
A ．电路中电流的最大值可达到0.6A B ．电压表的示数不能小于2V C ．可以将电阻箱的阻值调到4Ω D ．可以将电阻箱的阻值调到10Ω 【答案】BD 【解析】 【分析】 【详解】 A ．由图可知定值电阻1R 与电阻箱2R 串联，电流表测电路中的电流，电压表与电阻箱2R 并联，测电阻箱2R 两端的电压，由题意知允许通过1R 最大电流是0.4A ，允许通过电阻箱2R 的最大电流为1A ，电流表量程为0~0.6A ，根据串联电路中电流处处相等，可得电路中电流最大为0.4A ，故A 错误； B ．当电阻箱阻值最小，电路总电阻最小，电路中电流最大为0.4A 时，定值电阻1R 两端电压最大为 1U 大=1I R ?大=0.4A 10Ω?=4V 电源电压6V ，根据串联电路中各用电器两端电压之和等于电源电压可得，电阻箱2R 两端电压最小为 2U =小6V -4V=2V 即电压表的示数不能小于2V ，故B 正确； C D ．电阻箱2R 两端电压最小为2V ，电路中电流最大为0.4A ，由I = U R 可得电阻箱2R 的最小阻值 2R 小=2U I 小 大=2V 0.4A =5Ω 电压表量程0~3V ，则电阻箱2R 两端电压最大为3V ，此时电路中电流最小为 I 小=11U R 小=6V 3V 10Ω -=0.3A 电阻箱2R 的最大阻值 2R 大=2U I 大 小=3V 0.3A =10Ω 即电阻箱2R 的阻值范围是5Ω~10Ω，所以不可以将电阻箱的阻值调到4Ω，可以将电阻箱的阻值调到10Ω，故C 错误，D 正确。 故选BD 。 3．关于如图所示的课堂小实验，下列说法中正确的是（ ）

卜细胞 少，萝 ；D 成熟区，作用根吸 和 初中生物易错题归纳 一、吸水与失水 1、植物在生命活动过程中必须不断地从外界环境吸收水和无机盐，根是吸收水和无机盐的主要器官。下图分别表示根尖的结构和植物细胞吸水、失水状态的示意图，请据 图回答问题： （1）根是陆生植物吸水的主要器官，根吸收水和无机盐的主要部位是甲图中的【 D】成熟区。 （2）细胞中控制内外物质进出的结构是细胞膜。 （3）根吸收水分时，水分主要进入细胞内的结构是液泡。 （4）用糖拌西红柿，不久会有许多汁液流出，其原因是外界溶液的浓度大于（大于或小于）西红柿细胞的细胞液浓度，造成细胞失水，其状态如乙图所示。 （5）根细胞吸水的根本原因是土壤溶液浓度小于根细胞液浓度。（选填“大于”或“小于”） （6）根据以上实验结论，我们可以解释农业生产中一次施肥过多，会造成水稻的“烧苗”现象，这是因为（ A ） A.土壤溶液浓度过大，根细胞失水 B.土壤温度太高 C.水分太多，根无法呼吸 D.土壤缺乏足够的营养 2.学生兴趣小组为了研究外界溶液浓度对植物细胞吸水和失水的影响，设计了如下探究实验：取两个大小相同的萝卜，各从顶端向下挖一个大小一样的洞。在A萝卜洞内装 上浓盐水，在B萝卜洞内装上等量的清水，过一段时间后，观察萝卜洞内液面升降的变化（如图一）。 （1）该探究实验的变量是：外界溶液浓度。 （2）过了12小时候后观察发现：A萝卜洞里的水变多，萝卜变软；B萝卜洞里的水则变图一 变化。 卜变硬，那么，此时B萝图二发生了如图二中①（填序号）所示的 （3）得出结论：当外界溶液的浓度▲小于（大于或小于）萝卜细胞液浓度时，细胞吸水；反之则细胞失水。 相关知识：1.在细胞的结构中，保护细胞内部结构，维持细胞形态的是细胞壁；控制物质进出 的是细胞膜；与吸水和失水有关的是液泡，与光合作用有关的是叶绿体，与呼吸作用有关 的是线粒体。 2.在根尖的结构中，如图甲所示，A根冠，作用保护；B 分生区，作用细胞分裂；C 伸长区，作用根尖伸长失水 的主要器官。 二、泌尿系统 人体在新陈代谢中产生的废物主要通过泌尿系统排出体外，请根据泌尿系统结构示意图和下表中的相关信息回答： （1）人体泌尿系统的主要功能是形成和排出尿液，图②所示结构称之为输尿管，其主要作用是输送尿液。 （3）图③所示结构的功能是暂时贮存尿液。图中【①】肾脏是形成尿液的器官。 （2）根据表格中的数据可以判断 C 液为尿液，它可以暂时贮存在【③】膀胱中，一旦有尿意，应及时排出。 （3）若某人胰岛素分泌不足，则从【④】排出的液体中可检测出葡萄糖。可用胰岛素制剂来治疗。 （4）如果某人的尿液中出现了大量的蛋白质和血细胞，他有可能出现病变的是肾小管； （5）右图是尿液形成的示意图，图中①肾小囊中的液体是原尿；血浆中有大分子蛋白质，而原尿中没有，这是因为肾小球的滤过作用。 原尿中有葡萄糖而尿液没有，这是因为② 肾小管的重吸收。若化验出某人尿液中有葡萄糖，医生推断该病人的发病部位最可能是。三、无性生殖和有性生殖 1. 甲乙丙丁 （1）水蜜桃味美汁多，生产上常采用的繁殖方法是图【乙】芽接。 （2）图丙所示的生殖方式属于有性生殖，其种子中能萌发成幼苗的结构由受精卵发育而来。 （3）若要在短时间内生产出大批康乃馨等花卉幼苗，生产上常利用的技术是图【丁】组织培养。 2. 成分 A 液(克／100 毫升) B 液(克／100 毫升) C 液(克／100 毫升) 水90 98 96 蛋白质8.00 O.03 0.00 葡萄糖0.10 0.10 O.00 无机盐O.72 0.72 1.10 尿素0.03 0.03 1.80
