【备注】(1)惯性口诀 物体有惯性，惯性物属性；大小看质量，不论动与静．意思就是一切物体都有 惯性．惯性的大小只与质量有关，与速度及是否受力等其他因素无关． (2)惯性的正确理解 ①一切物体在任何状态下都具有惯性：物体的质量越大，惯性越大．惯性与物 体的运动速度无关．②惯性并不是力，所以不能说成惯性力或受到惯性的作用．③ 力是改变物体运动状态的原因，惯性是维持物体运动状态的原因． (3)用惯性解释现象的基本步骤 ①确认研究对象是哪个物体；②清楚它原来处于什么状态，后来发生了什么变 化；③这个物体(或物体的哪一部分)由于惯性继续保持原来的运动状态；④发生了某 种现象(或造成了某种结果)．

专题打破九课外探求型实验专题演练类型一电学类1．(2018·景德镇第一次质量检测)擅长观察的宁滨发现家里轿车的前灯有好几组，且灯丝粗细不同，发光的亮度也不同，他猜想车灯的亮度可能与灯丝的粗细有关，因而他设计了模拟电路，并选择以下器材：电源、滑动变阻器、小灯泡(L1“2.5 V 1.25 W”、L2“2.5 V0.5 W”各一只，代替轿车前灯)、电流表、电压表等进行实验来验证本人的猜想。

如图甲所示。

(1)闭合开关S，发现不管怎样挪动变阻器的滑片，灯泡L1、L2均不亮，A、V1无示数，V2有示数，则电路出现的故障是____________。

(2)排出故障后，挪动变阻器的滑片，分别读出电流表、电压表的示数，观察并记录灯泡发光情况，填入表一。

当变阻器滑片移至某一地位时，电流表的示数如图乙所示，则电路中的电流为____________A，此时发现灯L2发光异常耀眼，缘由是_____________________________，此时，他该当__________________________________________________。

(3)分析数据，可得结论：两灯串联，灯泡的灯丝越细，发光越______。

(4)然后，宁滨按图丙所示设计连接电路进行实验，记录的实验数据及景象如表二，根据表二可得出结论：两灯并联时，灯泡的灯丝越细，发光越______。

表一：表二：(5)宁滨完成实验后有困惑，经过向爸爸请教，明白了轿车的同侧前灯是可以不同时工作的，在额定电压相反时，若想要更换更亮的轿车前灯，应选择灯丝较______(选填“粗”或“细”)的灯泡。

2．(2019·原创)小强采用了如图所示的实验安装图对通电螺线管磁性强弱的影响要素进行了如下探求实验。

第2题图【进行实验】保持电流不变，将无磁性、长度和横截面积相反但材料不同的圆柱形物体分别插入通电螺线管中，用吸引物重的大小来显示通电螺线管的磁性强弱，多次实验后，将数据记录鄙人表中：插入物体不放物体软铁棒铁合金1铁合金2铜棒铝棒碳棒吸引的物重/N 几乎为00.50.60.35几乎为0几乎为0几乎为0【分析论证】(1)从表中数据可得出：当其他条件相反时，放入______________________________会影响通电螺线管的磁性强弱，这些物体均含有原磁体，而放入____________________几乎不影响通电螺线管的磁性强弱。
