高中物理人教（新课标）必修1同步练习：2.6伽利略对自由落体运动的研究B卷（精编）姓名:________ 班级:________ 成绩:________一、单选题 (共9题；共18分)1. （2分）针对伽利略对自由落体运动的研究内容及过程，有以下叙述：①伽利略后来借助数学知识发现，如果速度与位移成正比，将会推导出复杂的结论；②伽利略通过逻辑得出亚里士多德的结论是错误的；③伽利略做了大胆的猜想：落体运动应该是一种简单的运动，落体的速度与时间或位移成正比；④伽利略通过铜球沿阻力很小的斜面滚下这一严谨求实的实验测定，得出只要倾角一定，铜球的加速度不变，他进一步设想当倾角为90°时，运动变为自由落体，其性质不变，且所有物体下落的加速度都一样，到此人类终于认识到自由落体运动是匀变速直线运动了．根据伽利略研究的真实过程，请你做出科学合理的排序，你认为正确的是（）A . ①②③④B . ②③①④C . ①③②④D . ②①③④2. （2分） (2018高一上·金东期中) 如油画所示是伽利略研究自由落体运动时的情景，他设计并做了小球在斜面上运动的实验，关于这个实验的下列说法中不符合史实的是（）A . 伽利略以实验来检验速度与时间成正比的猜想是否真实B . 伽利略让小球沿阻力很小的斜面滚下是为了“冲淡”重力的影响C . 伽利略通过实验发现小球沿斜面滚下的运动是匀加速直线运动D . 伽利略用实验而不是外推的方法得到斜面倾角增大到90°小球仍然会保持匀加速运动3. （2分）伽利略在研究自由落体运动时，首先大胆地提出了“重物与轻物应该下落得同样快，落体运动也一定是一种最简单的变速运动”的观点，在研究力和运动的关系时，大胆地做出了“当球沿水平面滚动时，它的速度应该不增也不减”的判断…这一认识的飞跃过程在科学探究中称为“科学猜想”，它孕育了科学的重大发现．科学的猜想，能让人们在科学探究中把握住探究的方向，正确地设计实验，明确所需测量的物理量．科学猜想的提出，一般经历的过程是（）A . 认真观察现象，凭借感觉，大胆地猜想B . 认真观察现象，经逻辑分析、推理判断，大胆地猜想C . 认真观察现象，凭借生活经验，大胆地猜想D . 认真观察现象，凭实验验证，大胆地猜想4. （2分）关于物理学思想方法，下列说法中正确的是（）A . 著名的伽利略斜面实验，主要应用了控制变量方法B . 在定义“速度”、“加速度”等物理量时，主要应用了比值的方法C . 在研究加速度a和外力F、质量m的关系时，主要应用了等效替代的方法D . 在研究气体的温度不变时，压强与体积的关系时，主要应用了理想实验方法5. （2分） (2020高一上·重庆期中) 如图所示是伽利略研究自由落体运动时的情景，他设计并做了小球在斜面上运动的实验。

高中物理人教(新课标)必修1同步练习：14实验：用打点计时器测速度
高中物理人教（新课标）必修1同步练习：1.4实验：用打点计时器测速度一、单选题（共4题；共8分）1. 你左手拿一块表，右手拿一支笔，当你的合作伙伴沿直线运动拉动一条纸带，使纸带在你的笔下向前移动时，每隔1s用笔在纸带上点下一个点，这就做成了一台“打点计时器”．如果在纸带上打下了10个点，在打下的这些点的过程中，纸带的运动时间是（）A.1sB.9sC.10sD.11s2. 如图所示，你左手拿一停表，右手拿一画笔，在同伴沿直线牵动纸带的同时，用画笔在纸带上点下一个个点，这样，就做成了一台“打点计时器”．为了提高该计时器的准确性，应尽量（）A.让同伴匀速拉动纸带B.使打点节奏保持均匀不变C.使打点时间间隔接近于0.02sD.使打点节奏随同伴拉动纸带速度的增大而加快3. 如图所示，根据打点计时器打出的纸带判断哪条纸带表示物体做匀速运动(______) A.B.C.D.4. 一位同学在用打点计时器做实验时，纸带上打出的不是圆点，而是如图所示的一些短线，这可能是因为（）A.打点计时器错接在直流电源上B.电源电压不稳定C.电源的频率不稳定D.振针压得过紧二、多选题（共4题；共12分）关于打点计时器的原理和使用方法，下列说法中正确的是（）A.打点计时器应接交流电源，交流电频率通常为50HzB.如果纸带上相邻两个计数点之间有四个点，则相邻两个计数点间的时间间隔是0.08sC.如果打点计时器在纸带上打下的点先密集后稀疏，则说明纸带的速度是由小变大D.电磁打点计时器接在220V电源上，电火花打点计时器接在6V电源上关于电磁打点计时器的使用，下列说法正确的是（）A.电磁打点计时器使用的是10V以下的直流电源B.在测量物体速度时，先让物体运动，后接通电源C.使用的电源频率越高，打点的时间间隔就越小D.纸带上打的点越密，说明物体运动的越慢一辆小汽车在行驶过程中漏油了，假如每隔1s漏下一滴，车在平直公路上行驶，以下为同学根据漏下的油滴分析汽车的运动情况（已知汽车的运动方向不变）。

人教新课标物理高一必修1第三章3.2弹力同步练习一、单选题1．（2分）如图甲所示，在水平地面上固定一竖直轻弹簧，弹簧上端与一个质量为0.1 kg的木块A相连，质量也为0.1 kg的木块B叠放在A上，A、B都静止。
在B上作用一个竖直向下的力F使木块缓慢向下移动，力F大小与移动距离x的关系如图乙所示，整个过程弹簧都处于弹性限度内。
下列说法正确的是（）A．木块下移0.1m过程中，弹簧的弹性势能增加2.5 JB．弹簧的劲度系数为500 N/mC．木块下移0.1 m时，若撤去F，则此后B能达到的最大速度为4 m/sD．木块下移0.1 m时，若撤去F，则A、B分离时的速度为5 m/s2．（2分）如图所示，竖直悬挂一轻质弹簧，不挂钩码时弹簧下端指针所指刻度为8cm，挂上10N的钩码，指针所指刻度为10cm，此弹簧的劲度系数是（）A．150 N/m B．100N/m C．200N/ m D．500 N/m3．（2分）如图所示，木块A静止在斜面体B上。
设木块受到斜面体的支持力大小为N，摩擦力大小为f.当斜面体水平向左做加速度逐渐增大的加速运动时，若木块A相对于斜面体B始终保持静止，则()A．N增大, f增大B．N不变，f增大C．N减小,f先增大后减小D．N增大,f先减小后增大4．（2分）如图，A、B两物体叠放在水平地面上，A物体质量m=20kg，B物体质量M=30 kg。
处于水平位置的轻弹簧一端固定于墙壁，另一端与A物体相连，弹簧处于自然状态，其劲度系数为250 N／m，A与B之间、B与地面之间的动摩擦因数均为=0.5。
现有一水平推力F作用于物体B 上，使B缓慢地向墙壁移动，当B移动0.2m时，水平推力的大小为（g取10 m／s2）（）A．200 N B．250 N C．300 N D．350 N5．（2分）如图，L形木板置于粗糙水平面上，光滑物块压缩弹簧后用细线系住．烧断细线，物块弹出的过程木板保持静止，此过程（）A．弹簧对物块的弹力不变B．弹簧对物块的弹力逐渐增大C．地面对木板的摩擦力不变D．地面对木板的摩擦力逐渐减小6．（2分）如图所示，A、B两物体的质量分别是m1和m2，用劲度系数为k的轻弹簧相连，处于竖直静止状态．现对A施加竖直向上的力F将A提起，稳定时B对地面无压力．当撤去F，A由静止向下运动至速度最大时，重力做功为（）A．B．C．D．7．（2分）在光滑水平面上有一物块始终受水平恒力F的作用而运动，在其正前方固定一个足够长的轻质弹簧，如图所示，当物块与弹簧接触后向右运动的过程中，下列说法正确的是（）A．物块接触弹簧后立即做减速运动B．当物块的速度为零时，它所受的合力为零C．物块接触弹簧后先加速后减速D．当弹簧处于压缩量最大时，物块的加速度等于零8．（2分）如图所示，将两个相同的木块a、b置于固定在水平面上的粗糙斜面上，a、b中间用一轻弹簧连接，b的右端用平行于斜面的细绳与固定在斜面上的挡板相连。
