湖南省桃江县第一中学2019-2020年高一上学期期中考试 物理 一、选择题 1.下列关于质点的说法正确的是( ) A. 研究和观察日食时，可以把太阳看成质点 B. 研究地球的公转时，可以把地球看成质点 C. 研究地球的自转时，可以把地球看成质点 D. 原子核很小，可以把它看成质点 【答案】B 【解析】 【详解】研究和观察日食时，太阳的大小直接影响观察结果，所以不可以把太阳看成质点，故A错误；研究地球绕太阳的公转时，地球的大小对于和太阳之间的距离来说太小，可以忽略，所以可以把地球看成质点，故B正确；研究地球的自转时，地球有大小和形状不能忽略，不能看作质点，否则就无法分辨地球的转动故C错误；质点并不是体积很小，就能看成质点，而是物体自身大小对所研究的问题没有影响，虽然原子核很小，有时候不能把它看成质点，故D错误。所以B正确，ACD错误。 2.下列说法正确的是（） A. 加速度为零的质点一定处于静止状态 B. 加速度减小，质点速度的增量一定减小 C. 加速度变大，质点速度一定变大 D. 加速度越大，速度变化率一定越大 【答案】D 【解析】 【详解】A.加速度为零的质点处于静止或匀速直线运动。故A错误； B.加速度减小，如果速度方向与加速度方向相同，速度增加。故B错误； C.加速度变大，如果速度方向与加速度方向相反，速度减小，故C错误； D.加速度表示物体速度变化的快慢，速度变化越快，速度变化率越大，加速度也一定越大。故D正确。 3.一物体以a=4m/s2的加速度做匀加速直线运动，物体在任意1s内 A. 位移都是2m B. 位移比前1s增加2m
C. 末速度是初速度的4倍 D. 速度增加4m/s 【答案】D 【解析】 【详解】A.物体做匀加速直线运动，在任意1s 内的位移是不断增加的，不可能都是2m 。故A 错误。 B.由： △2241x aT ==?=4m 所以任意1s 内的位移比前1s 内位移增加4m 。故B 错误。 CD.由： △v at = 可知加速度为4m/s 2 ，任意1s 时间内，速度增加4m/s ，而末速度不一定是初速度的4倍。故C 错误，D 正确。 4.足球以4m/s 的速度飞来，运动员把它以12m/s 的速度反向踢出，踢球时间为0.2s ，设球飞来的方向为正方向，假设踢球的时间内足球做匀变速运动，则足球在这段时间内的加速度是（ ） A. －40m/s 2 B. 40m/s 2 C. －80m/s 2 D. 80m/s 2 【答案】C 【解析】 【详解】设球飞来的方向为正方向，则v 0=4m/s ； 运动员立即以12m/s 的速度反向踢出，则v =-12m/s ，方向为负。所以加速度为： 0124800.2 v v v a t t -?--= ===-? m/s 2 故选C 。 5.物体甲的速度-时间图象和物体乙的位移-时间图象分别如图所示，则两个物体的运动情况是（ ） A. 甲在0﹣4s 时间内有往返运动，它通过的总路程为12m B. 甲在0﹣4s 时间内通过的位移为零 C. 乙在t =2s 时速度方向发生改变，与初速度方向相反 D. 乙在0﹣4s 时间内通过的位移为零 【答案】B
一、第四章 运动和力的关系易错题培优（难） 1．如图甲所示，在光滑的水平面上有质量为M 且足够长的长木板，木板上面叠放一个质量为m 的小物块。现对长木板施加水平向右的拉力F ＝3t （N ）时，两个物体运动的a -－t 图象如图乙所示，若取重力加速度g ＝10 m/s 2，则下列说法中正确的是（ ） A ．图线Ⅰ是小物块运动的a －-t 图象 B ．小物块与长木板间的动摩擦因数为0.3 C ．长木板的质量M ＝1 kg D ．小物块的质量m ＝2 kg 【答案】B 【解析】 【分析】 【详解】 A ．根据乙图可知，在3s 以后，m 与M 开始发生相对运动，m 的加速度不变，其大小为23m/s ，所以Ⅰ是长木板的—a t 图象，故A 错误； B ．设小物块与长木板间的动摩擦因素为μ，根据牛顿第二定律可知 23m/s m a g μ== 解得 0.3μ= 故B 正确； CD ．当3s t >时，以M 为研究对象，根据牛顿第二定律可知 F mg Ma μ-= 即 kt mg Ma μ-= 解得 3mg a t M M μ= - 由此可得 332 M = 解得 2kg M = 在3s 内，以整体为研究对象，可得 F M m a =+() 即
=+? M m 3()1 所以 1kg m= 故CD错误。 故选B。 2．如图所示，将质量为2m的长木板静止地放在光滑水平面上，一质量为m的小铅块（可视为质点）以水平初速v0由木板A端滑上木板，铅块滑至木板的B端时恰好与木板相对静止。已知铅块在滑动过程中所受摩擦力始终不变。若将木板分成长度与质量均相等的两段后，紧挨着静止放在此水平面上，让小铅块仍以相同的初速v0由左端滑上木板，则小铅块将（） A．滑过B端后飞离木板 B．仍能滑到B端与木板保持相对静止 C．在滑到B端前就与木板保持相对静止 D．以上三答案均有可能 【答案】C 【解析】 【分析】 【详解】 在第一次在小铅块运动过程中，小铅块与木板之间的摩擦力使整个木板一直加速，第二次小铅块先使整个木板加速，运动到B部分上后A部分停止加速，只有B部分加速，加速度大于第一次的对应过程，故第二次小铅块与B木板将更早达到速度相等，所以小铅块还没有运动到B的右端，两者速度相同。 故选C。 考点：牛顿第二定律。 3．如图所示，斜面体A静止放置在水平地面上，质量为m的物体B在外力F（方向水平向右）的作用下沿斜面向下做匀速运动，此时斜面体仍保持静止。若撤去力F，下列说法正确的是（） A．A所受地面的摩擦力方向向左 B．A所受地面的摩擦力可能为零 C．A所受地面的摩擦力方向可能向右 D．物体B仍将沿斜面向下做匀速运动
