题型:实验题

某兴趣小组想通过物块在斜面上运动的实验探究“合外力做功和物体速度变化的关系”。实验开始前,他们提出了以下几种猜想:①W∝,②W∝v,③W∝v 2。他们的实验装置如图甲所示,PQ为一块倾斜放置的木板,在Q处固定一个速度传感器(用来测量物体每次通过Q点时的速度),每次实验,物体从不同初始位置处由静止释放。

同学们设计了以下表格来记录实验数据。其中L1、L2、L3、L4……,代表物体分别从不同初始位置处无初速释放时初始位置到速度传感器的距离,v 1、v 2、v 3、v 4……,表示物体每次通过Q点的速度。

实验次数1234…….
LL1L2L3L4…….
vv 1v 2v 3v 4……
他们根据实验数据绘制了如图乙所示的L-v图象,并得出结论W∝v 2。他们的做法是否合适,你有什么好的建议?

___________________________________________________________________。

在此实验中,木板与物体间摩擦力的大小_______(填“会”或“不会”)影响探究出的结果。
