几道物理题（英语好的进）
2.Cutting the air
When a piece of thread (e.g.,nylon) is whirled around with a small mass attached to its free end,a distinct noise is emitted.Study the origin of this noise and the relevant parameters.
5.Bright waves
Illuminate a water tank.When there are waves on the water surface,you can see bright and dark patterns on the bottom of the tank.Study the relation between the waves and the pattern.
6.Woodpecker toy
A woodpecker(啄木鸟) toy (see picture) exhibits an oscillatory(振动的) motion(移动,动作).Investigate and explain the motion of the toy.
8.Bubbles
Is it possible to float on water when there are a large number of bubbles present?Study how the buoyancy(浮力) of an object depends on the presence of bubbles.
9.Magnet and coin
Place a coin vertically on a magnet.Incline the coin relative to the magnet and then release it.The coin may fall down onto the magnet or revert to its vertical position.Study and explain the coin's motion.
10.Rocking bottle
Fill a bottle with some liquid.Lay it down on a horizontal surface and give it a push.The bottle may first move forward and then oscillate before it comes to rest.Investigate the bottle's motion.

不知道你是让做一个还是都做,其实任意一个都够写个小论文的
1.当一个类似尼龙的线在它的自由端缠一小团后,会发出噪声.学习噪声产生机理及其相关参数
2.在一个水槽中,水晃动时,对着水照射灯光,在水槽底面你会看多明纹和暗纹,学习明纹暗纹关系.
这个是波的干涉现象研究.明暗纹间的宽度与水振动高度有一定关系.
3.如图的啄木鸟有一系列的振动,调查并解释啄木鸟玩具振动的机理.
这个应该就是简单的动量守恒,以及角动量守恒之类的.
4.当有足够量的气泡时物体是不是就能浮在水上?研究当存在气泡的时候物体浮力是怎样的.
这个感觉有点难操作,泡泡不好整,包括泡泡的浮力计算也是相当复杂,也可能有简单的吧,你在了解下
5.垂直的将一枚硬币放在磁铁上方,接着使硬币与磁铁相对倾斜后释放.硬币将跌到或是重新垂直站立在磁铁上.研究并解释这一现象.
电磁场问题,表面磁场方向是平行的,硬币磁化后可以当场磁针理解了
6.在一个瓶子中加入一些水,水平放置后推动它,在它停止动之前,它会先向前运动然后做往返振荡运动.研究瓶子运动规律.
这个似乎有点难,没怎么学过流体力学,可以再问下别人.
再问： 谢谢你！！虽然时间过了不过还是很感谢。能不能告诉我你打算怎么设计实验（要有相关器材，我会给追加奖励的）
