高三物理第一轮复习《机械振动和机械波》 一、机械振动： （一）夯实基础： 1、简谐运动、振幅、周期和频率： （1）简谐运动：物体在跟偏离平衡位置的位移大小成正比，并且总指向平衡位置的回复力的作用下的振动。 特征是：F=-kx,a=-kx/m （2）简谐运动的规律： ①在平衡位置：速度最大、动能最大、动量最大；位移最小、回复力最小、加速度最小。 ②在离开平衡位置最远时：速度最小、动能最小、动量最小；位移最大、回复力最大、加速度最大。 ③振动中的位移x 都是以平衡位置为起点的，方向从平衡位置指向末位置，大小为这两位置间的直线距离。加速度与回复力、位移的变化一致,在两个“端点”最大，在平衡位置为零，方向总是指向平衡位置。 ④当质点向远离平衡位置的方向运动时，质点的速度减小、动量减小、动能减小，但位移增大、回复力增大、加速度增大、势能增大，质点做加速度增大减速运动；当质点向平衡位置靠近时，质点的速度增大、动量增大、动能增大，但位移减小、回复力减小、加速度减小、势能减小，质点做加速度减小的加速运动。 ④弹簧振子周期：T= 2 (与振子质量有关,与振幅无关) （3）振幅A ：振动物体离开平衡位置的最大距离称为振幅。它是描述振动强弱的物理量, 是标量。 （4）周期T 和频率f ：振动物体完成一次全振动所需的时间称为周期T,它是标量，单位是秒；单位时间内完成的全振动的次数称为频率，单位是赫兹（Hz ）。周期和频率都是描述振动快慢的物理量，它们的关系是：T=1/f. 2、单摆： （1）单摆的概念：在细线的一端拴一个小球，另一端固定在悬点上，线的伸缩和质量可忽略，线长远大于球的直径，这样的装置叫单摆。 （2）单摆的特点： ○ 1单摆是实际摆的理想化，是一个理想模型; ○ 2单摆的等时性，在振幅很小的情况下，单摆的振动周期与振幅、摆球的质量等无关; ○3单摆的回复力由重力沿圆弧方向的分力提供，当最大摆角α<100 时，单摆的振动是简谐运动，其振动周期T= g L π 2。 （3）单摆的应用：○1计时器；○2测定重力加速度g=2 24T L π. 3、受迫振动和共振： （1）受迫振动：物体在周期性驱动力作用下的振动叫受迫振动，其振动频率和固有频率无关，等于驱动力的频率；受迫振动是等幅振动，振动物体因克服摩擦或其它阻力做功而消耗振动能量刚好由周期性的驱动力做功给予补充，维持其做等幅振动。 （2）共振：○1共振现象：在受迫振动中，驱动力的频率和物体的固有频率相等时，振幅最大，这种现象称为共振。 ○ 2产生共振的条件：驱动力频率等于物体固有频率。○3共振的应用：转速计、共振筛。 4、简谐运动图象： （1）特点：用演示实验证明简谐运动的图象是一条正弦（或余弦）曲线。 （2）简谐运动图象的应用： ①可求出任一时刻振动质点的位移。 ②可求振幅A ：位移的正负最大值。 ③可求周期T ：两相邻的位移和速度完全相同的状态的时间间隔。 ④可确定任一时刻加速度的方向。 ⑤可求任一时刻速度的方向。 ⑥可判断某段时间内位移、回复力、加速度、速度、动能、势能的变化情况。 πm K

高一物理机械运动、位移典型例题 [例1]甲、乙、丙三架观光电梯，甲中乘客看一高楼在向下运动；乙中乘客看甲在向下运动；丙中乘客看甲、乙都在向上运动.这三架电梯相对地面的运动情况是[] A.甲向上、乙向下、丙不动 B.甲向上、乙向上、丙不动 C.甲向上、乙向上、丙向下 D.甲向上、乙向上、丙也向上，但比甲、乙都慢 [分析]电梯中的乘客观看其他物体的运动情况时，是以自己所乘的电梯为参照物.甲中乘客看高楼向下运动，说明甲相对于地面一定在向上运动.同理，乙相对甲在向上运动，说明乙对地面也是向上运动，且运动得比甲更快.丙电梯无论是静止，还是在向下运动，或以比甲、乙都慢的速度在向上运动，丙中乘客看甲、乙两电梯都会感到是在向上运动. [答] B、C、D. [例2]下列关于质点的说法中，正确的是[] A.体积很小的物体都可看成质点 B.质量很小的物体都可看成质点 C.不论物体的质量多大，只要物体的尺寸跟物体间距相比甚小时，就可以看成质点 D.只有低速运动的物体才可看成质点，高速运动的物体不可看作质点 [分析] 一个实际物体能否看成质点，跟它体积的绝对大小、质量的多少以及运动速度的高低无关，决定于物体的尺寸与物体间距相比的相对大小.例如，地球可称得上是个庞然大物，其直径约为1.28×107 m，质量达到6×1024kg，在太空中绕太阳运动的速度每秒几百米.由于其直径与地球离太阳的距离（约1.5×1011m）相比甚小，因此在研究地球的公转运动时，完全可以忽略地球的形状、大小及地球自身的运动，把它看成一个质点. [答] C.
[例3]下列各种情况，可以把研究对象（黑体者）看作质点的是[] A. 研究小木块的翻倒过程 B. 讨论地球的公转 C. 解释微粒的布朗运动 D. 计算整列列车通过某一路标的时间 [误解一] 小木块体积小，远看可视为一点；作布朗运动的微粒体积极小，当然是质点，故选（A）、（C）。 [误解二] 列车作平动，车上各点运动规律相同，可视为质点，故选（D）。 [正确解答] 讨论地球的公转时，地球的直径（约1.3×104km）和公转的轨道半径（约1.5×108km）相比要小得多，因而地球上各点相对于太阳的运动差别极小，即地球的大小和形状可以忽略不计，可把地球视为质点，故选（B）。 [错因分析与解题指导] 物理研究中常建立起一些理想化的模型，它是物理学对实际问题的简化，也叫科学抽象。它撇开与当前观察无关的因素和对当前考察影响很小的次要因素，抓住与考察有关的主要因素进行研究、分析、解决问题，质点就是一个理想化的模型。[误解一] 以为质点是指一个很小的点。但在小木块的翻倒过程中，木块各点绕一固定点转动，各点运动情况不同，不可看作质点。至于作布朗运动的粒子，尽管体积极小，仍受到来自各个方向上的液体分子（具有更小体积）的撞击，正是这种撞击作用的不平衡性使之作无规则运动，也不可把布朗运动粒子视为质点。[误解二]以为火车在铁道上的运动为平动，可视为质点。而本题实际考察的是经过某路标的时间，就不能不考察它的长度，在这情况中不能视其为质点。 [例4]关于质点的位移和路程的下列说法中正确的是[] A. 位移是矢量，位移的方向即质点运动的方向 B. 路程是标量，即位移的大小 C. 质点沿直线向某一方向运动，通过的路程等于位移的大小 D. 物体通过的路程不等，位移可能相同 [误解]选（A），（B）。

九、机械振动 一、知识网络 二、画龙点睛 概念 1、机械振动 (1)平衡位置：物体振动时的中心位置，振动物体未开始振动时相对于参考系静止的位置，或沿振动方向所受合力等于零时所处的位置叫平衡位置。 (2)机械振动：物体在平衡位置附近所做的往复运动，叫做机械振动，通常简称为振动。 (3)振动特点：振动是一种往复运动，具有周期性和重复性 2、简谐运动 (1)弹簧振子：一个轻质弹簧联接一个质点，弹簧的另一端固定，就构成了一个弹簧振子。 (2)振动形成的原因 ①回复力：振动物体受到的总能使振动物体回到平衡位置，且始终指向平衡位置的力，叫回复力。 振动物体的平衡位置也可说成是振动物体振动时受到的回复力为零的位置。
②形成原因：振子离开平衡位置后，回复力的作用使振了回到平衡位置，振子的惯性使振子离开平衡位置；系统的阻力足够小。 (4)简谐运动的力学特征 ①简谐运动：物体在跟偏离平衡位置的位移大小成正比，并且总指向平衡位置的回复力的作用下的振动，叫做简谐运动。 ②动力学特征：回复力F与位移x之间的关系为 F＝－kx 式中F为回复力，x为偏离平衡位置的位移，k是常数。简谐运动的动力学特征是判断物体是否为简谐运动的依据。 ③简谐运动的运动学特征 a＝－k m x 加速度的大小与振动物体相对平衡位置的位移成正比，方向始终与位移方向相反，总指向平衡位置。 简谐运动加速度的大小和方向都在变化，是一种变加速运动。简谐运动的运动学特征也可用来判断物体是否为简谐运动。 例题：试证明在竖直方向的弹簧振子做的也是简谐振运动。 证明：设O为振子的平衡位置，向下方向为正方向，此时弹簧形变量为ｘ0，根据胡克定律得 ｘ0＝mg/k 当振子向下偏离平衡位置ｘ时，回复力为 F＝mg－ｋ(ｘ＋ｘ0) 则Ｆ＝－kx 所以此振动为简谐运动。 3、振幅、周期和频率 ⑴振幅 ①物理意义：振幅是描述振动强弱的物理量。 ②定义：振动物体离开平衡位置的最大距离，叫做振动的振幅。 ③单位：在国际单位制中，振幅的单位是米(m)。
