One day a new teacher came to this school. When he heard that, he came up w 小题2:   a good idea. He told each of his students to b 小题3:   a clear plastic bag and a bag of potatoes to school. For every person they didn’t want to forgive in their lives, they chose a potato, wrote the person’s name on it, and put it in the plastic bag.

题型:实验题

二位同学根据不同的实验条件,进行了探究平抛运动规律的实验:

(1)甲同学采用如图甲所示的装置.用小锤击打弹性金属片,金属片把A球沿水平方向弹出,同时B球被松开自由下落,观察到两球同时落地,改变小锤打击的力度,即改变A球被弹出时的速度,两球仍然同时落地,这说明________________________。

(2)乙同学采用如图乙所示的装置.两个相同的弧形轨道M、N,分别用于发射小铁球P、Q,其中N的末端可看作与光滑的水平板相切,两轨道上端分别装有电磁铁C、D;调节电磁铁C、D的高度使AC=BD,从而保证小铁球P、Q在轨道出口处的水平初速度v0相等.现将小铁球P、Q分别吸在电磁铁C、D上,然后切断电源,使两小球能以相同的初速度v0同时分别从轨道M、N的末端射出。实验可观察到的现象应是______________.仅仅改变弧形轨道M的高度,重复上述实验,仍能观察到相同的现象,这说明_______________。
