伽利略在《两种新科学的对话》一书中，讨论了自由落体运动和物体沿斜面运动的问题，提出了这样的猜想：物体沿斜面下滑是一种匀变速直线运动，同时他还运用实验验证了其猜想。物理兴趣小组依据伽利略描述的实验方案，设计了如图所示的装置，探究物体沿斜面下滑是否做匀变速直线运动。

（1）实验时，让滑块从某一高度由静止沿斜面下滑，并同时打开装置中的阀门，使水箱中的水流到量筒中；当滑块碰到挡板的同时关闭阀门（整个过程中水流可视为均匀稳定的）。改变滑块起始位置的高度，重复以上操作。该实验探究方案是利用量筒中收集的水量来测量___________的。

（2）下表是该小组测得的有关数据，其中S为滑块从斜面的不同高度由静止释放后沿斜面下滑的距离，V为相应过程量筒收集的水量。分析表中数据，根据___________________________，可以得出滑块沿斜面下滑是做匀变速直线运动的结论。

（3）本实验误差的主要来源有：水从水箱中流出不够稳定，还可能来源于___________________________等。（只要求写出一种）
