小明在“测滑轮组机械效率”的实验中,用如图1所示的滑轮组进行了三次实验,实验数据如下表:

(1)分析表中数据,回答以下问题:

①表中有一个数据的记录是错误的,错误的数据是    

(2) 在操作时注意拉动测力计沿           运动。如果在静止时读出测力计拉力大小,所计算得机械效率比实际效率    (高/低),

(3)小红在小明实验的基础上多使用一个滑轮也做了该实验,如图2所示。

①小红多使用一个滑轮,目的是为了                                

②当这两位同学使用各自的滑轮组提升相同的重物上升相同高度时,若忽略绳重及摩擦,它们的机械效率    (相同/不相同),理由是:                       

(4)为了将放置在水平地面上、重G=120N的重物提升到高处,某同学设计了如右图(甲)所示的滑轮组装置。当他用下图(乙)所示随时间变化的竖直向下拉力F拉绳时,重物的速度v和上升的高度h随时间t变化的关系图像分别如图(丙)和(丁)所示,不计摩擦,绳对滑轮的拉力方向均可看成在竖直方向。则在2~3s内,拉力F做的功    J;在1~2s内,拉力F做的功的功率为    W。
