韶中欢1369弹力测力计的使用方法如题 -
颜博鸦19250604081 ______[答案] 一、被测物体重力不能超过弹簧测力计的量程; 二、读数时,视线应垂至于刻度; 三、在测量前,迎先调零; 四、不用刻度已被损坏的弹簧测力计; 五、待示数稳定后才读数. 我记得好像应该只有这么多.如果是测摩擦力,要匀速拉动弹簧测力计.

韶中欢1369使用弹簧测力计测量力的步骤使用弹簧测力计的步骤中,正确的操作顺序应为_______1.轻轻来回拉动挂钩 2.把待测施力加在挂钩上 3.观察弹簧测力计的量... -
颜博鸦19250604081 ______[答案] 顺序:3-4-1-2-5 1的作用:①防止挂钩和外壳有摩擦 ②看挂钩能否回到原刻度(为了看挂钩能否回到原刻度,为了方便读数,原刻度一般是0N,即先调整弹簧测力计指针位置,再轻轻来回拉动挂钩)

韶中欢1369弹簧测力计的正确使用方法是:(1)测量前要了解弹簧测力计的______,要明确______,还必须要______.(2)在实际测量时,要使弹簧测力计内的弹簧... -
