(2分)如图所示，平衡杠杆AOB，O为支点，请作出物体M所受重力的示意图和动力 F的力臂l.18. (2分)一个工人站在地面上，使用如图所示的滑轮组将重物从地面提升到楼顶，要求绳子的自由端要向下拉，请你用笔画线代替绳子，画出滑轮组最省力的绕绳方法.四、实验探究题(共26分)19. (12分)“探究动能大小与哪些因素有关”的实验装置如图1所示：将小车从斜面上高h处由静止释放，运动至木板上后与木块碰撞.通过改变小车释放时的高度h、在小车中增加钩码和在木板上铺垫棉布的方法，得到了图2 虚线框内的四个实验场景.(1)为探究小车动能与质量的关系，应选用场景①和 (选填“②”“③”或“④”)进行实验；选用场景③和④进行实验时，可探究小车动能与的关系.(2)在实验中，小车动能越大，发生碰撞时对木块所做的功就越，木块被碰撞后在木板上 .(3)若将场景①和②中的木块均移走，利用这两个场景可探究对物体运动的影响.为提高实验结论的准确性，还需再增加一次实验，因此，在场景①的基础上，你所做的调整是： .20. (14分)日常生活和工农业生产中，提高机械效率有着重要的意义，提高机械效率，要从研究影响机械效率的因素出发，寻求办法.(1)为了探究影响机械效率的因素，小明选取了大小相同的滑轮，利用图甲和图乙装置进行实验，并把数据记录在下表中.实验次数滑轮材质钩码重G/N提升的高度h/m有用功W有/J拉力F/N绳端移动的距离 s/m总功W总/J机械效率η1铝10.10.10.60.30.1856%2铝20.10.2 1.00.30.367%3铝20.20.4 1.00.60.667%4塑料20.20.40.80.60.4883%5塑料20.20.4 2.10.20.4295%①比较 1 和2 两次实验发现：在所用滑轮组一定时，提升的钩码，机械效率越高.②比较3 和4 两次实验发现：滑轮组的机械效率还与有关.③比较两次实验发现：在所用滑轮组一定时，机械效率与提升钩码的高度无关.④第5次实验是利用图的装置完成的，判断依据是 .⑤利用图甲的装置，把重6N的物体用2.5N的拉力匀速拉起，滑轮组的机械效率为 .可见如果没有刻度尺，只有测力计，也可以测量出滑轮组的机械效率.(2)小明利用图丙装置实验发现：斜面的机械效率与斜面的倾斜程度和摩擦力有关，与物重无关.保持斜面倾斜程度不变，可以采用的方法减小摩擦，从而提高斜面的机械效率.五、计算题(共12分)21. 科技馆里两位老人正饶有兴致地体验升降座椅装置，小明观察后画出简图(如图)进行研究.若爷爷质量m人=60kg，奶奶用F=240 N的拉力将爷爷匀速拉升到顶端，该过程中奶奶手握住绳子向下拉动的总长度s=6m.不计绳重和摩擦，g取10 N/ kg.求：(1)奶奶所做的功；(2)动滑轮(含座椅)的质量；(3)该升降座椅装置的机械效率(保留一位小数).专项训练卷 (三)功和机械能、简单机械1. D2. B3. B4. B5. D6. C7. B8. C9. D10. A 【解析】由于物体M做匀速直线运动，动滑轮也在做匀速直线运动，对动滑轮进行受力分析，弹簧秤对动滑轮的拉力与绳子对动滑轮的拉力之和等于F，又由于弹簧秤的拉力与绳子对动滑轮的拉力相等，所以F=20N+20N=40 N；①因为M做匀速直线运动，在水平方向上，绳子对M 的拉力与地面对M的摩擦力是一对平衡力，所以M受到地面的摩擦力为20 N，①正确；②M受到的摩擦力方向与绳子对M的拉力方向相反，所以M受到地面的摩擦力的方向水平向右，②错误；③动滑轮运动的速度为 M运动速度的一半，即拉力 F的功率P=W=tFs=Fv轮=40N×0.1m/s=4W,③错误;④M受到的重力与地面对M的支持力，这两个力大小相等，t方向相反，作用在同一个物体上，且作用在同一条直线上，是一对平衡力，④正确.综上所述，正确的是①④，故选 A.11. 300 3600 12. 增大减小 13. 1.4 14. 60 16015.4.5×10⁶定 2.7×10⁷ 4.5×10⁴16. 1 右 0.7 【解析】设小明在距扁担左端l处挑起才能使扁担水平，根据杠杆平衡条件有：20kg×g×l=25kg×g×(1.8m−l),解得l=1m;；若将两筐谷子同时向内移动了0. 1m ,则20kg×g×0.9m>25kg×g×0.7m,因此需要向右筐增加谷子；设向右筐增加m谷子才能基本保持扁担水平，则再由杠杆平衡条件得：20kg×g×0.9m=(25kg+m)×g×0.7m,解得m≈0.7kg.17. 如图所示 18. 如图所示19.
