2.(2010年湛江一模)(1)(9分)①用游标卡尺(卡尺的游标有20等分)测量一支铅笔的长度,测量结果如下图所示,由此可知铅笔的长度是      cm。

 

②在“研究匀变速直线运动”的实验中,如图为实验得到的一条纸带,纸带上每相邻的两计数点间的时间间隔均为0.1s,测得A到B和B到C的距离分别为5.60cm和7.82cm,则物体的加速度大小为     m/s2,B点的速度大小为      m/s。

1.(2010年3月茂名一模)(12分)某实验小组利用如图甲所示的气垫导轨实验装置来探究当合外力一定时,物体运动的加速度与其质量之间的关系.

1由图甲中刻度尺读出两个光电门中心之间的距离s=24cm,由图乙中游标卡尺测得遮光条的宽度d=    cm.该实验小组在做实验时,将滑块从图甲所示位置由静止释放,由数字计时器可以读出遮光条通过光电门1的时间Δt1,遮光条通过光电门2的时间Δt2,则滑块经过光电门1时的瞬时速度的表达式v1=      ,滑块经过光电门2时的瞬时速度的表达式v2 =      ,则滑块的加速度的表达式a=       .(以上表达式均用字母表示)

2某同学用质量为100g滑动块做实验,每次实验在吊挂之处逐次增加一个质量为50g的砝码,细绳质量可忽略,则下列曲线何者最适合描述滑块加速度随着吊挂砝码个数的变化

3.(2010年韶关一模)  (1)在用打点计时器验证机械能守恒定律的实验中,质量m=1.00kg的重物自由下落,打点计时器在纸带上打出一系列点. 如图所示为选取的一条符合实验要求的纸带,O为第一个点,ABC为从合适位置开始选取的三个连续点(其他点未画出).已知打点计时器每隔0.02s打一次点,当地的重力加速度g=9.80m/s2.那么:

①纸带的    端(选填“左”或“右”)与重物相连;

   ②根据图上所得的数据,从O点到B点,重物重力势能减少量=     J,动能增加量=       J;(结果取3位有效数字)

  ③实验的结论是                  .

[答案](1)①左②1.88 1.84③物体只受重力作用,在误差允许范围内,重物减小的重力势能等于增加的动能,即机械能守恒.
