1、Chapter 17 INERTIA第 17 章 慣性Why should graviion, of all the many forin nature, be the only one to be soimay related to inertia, which issuped to be an Inherent property of bodiest is Independent of the nature of the force being exerted?-Peter J. Brancazio“為什么重力，在自然界眾多力中，是唯一和慣性相關(guān)的力，被假定為物體的屬性，和外部力無關(guān)？”-

2、Peter J. BrancazioI will begin the subject of inertia with a quoion* from the exceptionally well-written book entitled The Nature ofPhysics by Peter J. Brancazio.我將以Peter J. Brancazio 寫的非常好的 The Nature of Physics 中的一段來開始慣性的話題。30. A.Quoting from pages 146 and 147:30.A引自 146 和 147：INERTIA AND GRAVIION

3、 慣性和重力One aspect of graviionand inertia. This relationship ist may provide a clue as wits ultimate nature is the peculiar relationship betn graviionmost poedly illustrated when we re-examine in detail the derivation from Newtonianprinciples of the law ofalling body of mass mlling bodies. Newton deri

4、ved the law by substituting the graviional force beto the equation F = ma:n the earnd a重力的一方面提供了一個線索，重力和慣性最終定理的一個奇怪的關(guān)系。這種關(guān)系是非常明顯的，當(dāng)重新詳細(xì)檢查關(guān)于下落物體定理時。導(dǎo)出定理是通過用等式 F = ma 替換地球和下落物體間重力，下落物質(zhì)質(zhì)量為 m。GME/RE2The next step is to cancel the m on both sides of the equation, with the resultt the acceleration a=isind

5、ependent of the mass of the falling body. Hereins the mystery.下一步是消去等式兩邊的 m，結(jié)果是加速度為a= GME/RE2，和下落物體的質(zhì)量無關(guān)。此中有一個的。The mt appearshe equation F =ma is a measure of the inertia of the body. It measures theof a body toany force. Let us call this the inertial mass. The mt appears in the equation F = GMm/d2

6、 determines the strength of aparticulareraction involving the body- namely, the graviional force. Let us call this the graviional mass. The inertial andgraviional masses must be exactly equal; otherwise we could not cancel themhe above equation. If they did not cancel,we would arrive at thet the acc

7、eleration of a falling body does depend on its mass (either inertialraviional,or both), which is contrary to experience. The theory of graviion would be incorrect.F =ma 中的 m 是物體慣性的估量。它測量的是物質(zhì)對任何力的抗性。讓稱它為慣性質(zhì)量。F = GMm/d2 中的 m決定一種特殊的物體參與的交互強(qiáng)度-稱作重力。不能在一個等式中消除它們。如果它們不能消除，稱它為引力質(zhì)量。慣性質(zhì)量和引力質(zhì)量必須精確相等；否則會得到下落物體的

8、加速度依賴于它的質(zhì)量（慣性質(zhì)量，或兩者）的結(jié)論，這和的經(jīng)驗(yàn)是相反的。引力理論將是不正確的。Therefore, we seet Newton did not really derive the law of falling bodies; rather, the law of falling bodies (anexperimental result) forced him to amet the inertial and graviional masses must be equal.因此，看到?jīng)]有真正導(dǎo)出下落物體定律；相反，下落物質(zhì)定律（一個經(jīng)驗(yàn)結(jié)果）強(qiáng)迫它假定慣性質(zhì)量和引力質(zhì)量必須相等。

9、The equality of the inertial and graviional masses is extremely puzzling to physicists. Why should graviion, of all themany forin nature, be the only one to be soimay related to inertia, which iped to be an inherent property ofn inertia and gravity - twobodiest is independent of the nature of the fo

10、rce being exerted? This connection betcompley different and otherwise unrelated properties of bodies -has thus far eluded an explanation. In fact, Einstein looked on the equality of inertial and graviional mass as a fundamental principle of nature and used it as a starting pofor thegeneral theory of

11、 relativity. This theory provided yet another conceptualization of gravity. Einsteins theory of graviion is fartoo complex to summarize in a few senten, so we will defer a discusof it until a later chapter. In any case, the equalityof the inertial and graviional masses is clearly an important clue a

12、s to the fundamental nature of graviion (and inertwell). This equality must be explained by future physicists if a deeper comprehenachieved.of graviion and inertia is to be慣性質(zhì)量和引力質(zhì)量的相等極度困惑著物理學(xué)家。為什么重力，在自然界眾多力中，是唯一和慣性相關(guān)的力，被假定為物體的屬性，和外部力無關(guān)？慣性和引力的聯(lián)系-兩個物質(zhì)完全無關(guān)的屬性-至今沒有一個解釋。實(shí)際上，愛因斯坦看到了慣性質(zhì)量和引力質(zhì)量的相等性，以此為基礎(chǔ)提出了

13、廣義相對論。這個理論提出了另一個引力的概念。愛因斯坦的引力理論復(fù)雜到不能總結(jié)為幾句話，所以以后的章節(jié)再。不管如何，慣性質(zhì)量和引力質(zhì)量的相等是引力（和慣性）理論基礎(chǔ)的重要提示。如果要深入理解引力和慣性，這種相等必須被將來的物理學(xué)家解釋。In view of the lack of a fundamentaderstanding of the nature of gravity, it seems remarkablet Newtons theory ofgraviion could have brought about such an enormous advance in our unders

14、tanding of the universe. But this is characteristicof the way in which science progresses. It is not nesary to understand gravity fully in order to have a sucsful theory ofgraviion. Simply by accepting the concept of graviion as an axiom, we can account for a wide variety of seeminglyunrelated pheno

15、mena in relatively simple terms. Thus in view of its simplicity, comprehensiveness, and predictiveer, thetheory of graviion must be considered an outstanding theory. The attempts on the part of some physicists to understandgravity represent the next seanswers exist.ans attempt to probe ever more dee

16、ply until the ultimate answers are found- if, in fact, such鑒于對引力理論缺少基礎(chǔ)的理解，似乎的引力理論給對宇宙的理解帶來很大進(jìn)步。但這是科學(xué)過程的特點(diǎn)。為了一個成功的引力理論，不需要完全明白引力。簡單的把引力的概念當(dāng)作公理，可以用簡單的術(shù)語說明種種看起來無關(guān)的現(xiàn)象。因此，鑒于它的簡單性、綜合性和學(xué)家試圖“理解”引力，表示人類試圖探索更深入的最終性，引力理論必定會被認(rèn)為是杰出的理論。一部分物理-如果，實(shí)際上，這個是存在的。*RepredwithpermisofMacMillanPublishingCompanyfromThe Natur

Such a description is thesame fravity, exceptt gravity can be observed as either Unobvious or Obvious.關(guān)于于星球（太空中的大物體）對其它物體的“引力”的本質(zhì)的觀察明顯的“力效應(yīng)”。這種效應(yīng)在有些時候是不可見的。物體“重量”的力學(xué)效果是完全是組成物體的陀螺子、不均衡電荷

21、和特定引力場的不可見“力效果”的結(jié)合。這種描述對重力也是一樣的，此外策略可以是“不可見”或“可見”的。C. I will now demonstratet the Inertia of a mass is also mechanically related to thety ofgyroscopic-action-particles comprisingt mass. Inertia is simply the Unobvious, mechanical effects of the speed of thegyroscopic action of the basic building ent

22、ity of all matter: the Gyroscopic Particle!C.我現(xiàn)在將證明物質(zhì)的“慣性”和組成物質(zhì)的陀螺子數(shù)量也是相關(guān)的。慣性是簡單的組成所有物質(zhì)的基本實(shí)體-陀螺子-的陀螺運(yùn)動“速度”的不可見力學(xué)效果。Consequently, one can easily mechanically understand why inertia and graviional masses are equal.因此，可以很容易理解為什么慣性質(zhì)量和引力質(zhì)量是相等的。They both represent one and the same gyroscopic- action-entit

23、y (see Section 30-A) which demonstrates the mathematicaloneness of the two effects.兩者代表了同樣的陀螺實(shí)體（看 30-A 部分），證明了兩者效果的數(shù)學(xué)上的“唯一性”。The following quote is a tribute to Michael Faraday:下面的是一個對法拉第的稱贊：Faraday, in his last years, tried to show experimentally a relation betn gravity and electricity, concluding

24、his prwith, Here end my trials for the present. The results are negative; they do not shake my strong feeling of the existence of arelation betn gravity and electricity, though they give no prooft it exists. “法拉第，在他最后的幾年，試圖用實(shí)驗(yàn)展示重力和電的關(guān)系，他總結(jié)到，現(xiàn)在我終止了嘗試。結(jié)果是不好的；但它們沒有讓我動搖重力和電存在關(guān)系的強(qiáng)烈感覺，雖然它們沒有證明它的存在?！盌.To u

25、nderstand the relation betn graviion and inertia, one musthave the proper mental. Theeffect of inertia is extremely small. Therefore, the mechanical essence of inertia can be very deceptive.D.為了理解重力和慣性的關(guān)系，必須先有獨(dú)特的洞察力。慣性的效果是極小的。因此，慣性的力學(xué)本質(zhì)是非常令人迷惑的。Imagine a massive log lying on the Earthrface. As one a

26、ttempts to lift even the logs end (see Figure 30-D),ouldencounter greatdue to the gravity effect. (This effect was originally explained in Section 29-H.)想象一個很重的原木放在地表。當(dāng)一個人試圖抬起原木的一端時（看圖 30-D），將要克服“策略效應(yīng)”導(dǎo)致的阻力。（這種效果在 29-H 部分開始解釋。）E. Have the same massive log suspended by a cable and attached to a suppo

27、rt which permits the massive log to balance inthe air. (See ,Figure 30-E.)E.用纜繩將同樣的原木懸掛起來，使原木在空中平衡。（看圖 30-E）his exle, one has mechanically produced an Unobvious Force which does not in any way cancel the gravityeffect, bus simply counter equaled the gravity effect with respect to the massive log. In

One can easily seet Figure 30-E demonstrates two pos:F.可以很容易看出，圖 30-E 證明了兩點(diǎn)：(1)

29、Even when the gravity effect was counter-equaled, there remained some type of(Unobvious) force to themovement oft mass. This(Unobvious) force is called inertia.(2) The Facts showt such inertia -as a resistive (Unobvious) force -is extremely weak compared to electric ormagnetic forwhich have a unity

30、factor of 1.（1）即使當(dāng)“重力”被抵消，移動物體依然有幾種阻力（不可見）。這種（不可見）阻力叫做“慣性”。（2）事實(shí)說明，這種“慣性”-作為一種（不可見）的阻力-和“整體 1”的電場力或磁場力相比是極弱的。G. One can concludet this weak, inertia-mass effect is only some percentage of the unity factor of 1 and similar tothe weak gravity-mass effect.G.可以總結(jié)出，這種弱小的“慣性質(zhì)量效應(yīng)”是只“整體 1”的幾個百分點(diǎn)，類似于弱小的“重力效應(yīng)

31、”CONSIDER THE FOLLOWING: Einsteins General Theory of Relativity has been criticized for its failure to explaheconcept of inertia. In Newtonian mechanics, it is sed as a fundamental principlet bodiessess inertia, but it is notexplained why bodiessess this property.考慮下面：的廣義相對論因?yàn)闉槟芙忉寫T性指責(zé)。在力學(xué)中，慣性是物體擁有的基

32、礎(chǔ)原則，但沒解釋為什么物體有這種屬性。H. Consider the following experiment: a two-foot diameter, fiberglass ball has a 10-pound, one-foot diameter gyroscopehidden inside (see Figure 30-H) which has been roed to 30,000 RPM (perfectly balanced). An uneducated man walks up tothe ball and starts rolling it. As long as he

33、rolls the ball in a directiont does not change the plane of axis of theernalgyroscope, the ball will roll relatively easily. However, when he tries to roll the ball in a direction which apps a force whichattempts to tilt the axis of theernal gyroscope, the uneducated man would be dumbfounded since t

34、he ball would then resisthim with great force. The ball would start gyrating in a roional motion at right angles to the direction he pushed the ball. Theball would grey resist his efforts to accelerate or reverset roional gyration. If, at a later time, someone informed himabout the inertia of an obj

35、ect, he would comment, I know of an objectcause for the difference in observed results is caused by the speed of thes a varying inertia. In essence, the mechanicalernal mass!H.考慮下面的實(shí)驗(yàn)：一個兩英尺直徑玻璃球重 10 磅，一英尺直徑的陀螺儀放在里面（看圖 30-H），轉(zhuǎn)速 30000轉(zhuǎn)每分鐘（完美平衡）。一個沒上過學(xué)的人來到球前開始旋轉(zhuǎn)它。只要他在不改變陀螺儀軸面的方向旋轉(zhuǎn)，球?qū)⑾鄬θ菀仔D(zhuǎn)。然而，當(dāng)他試圖在傾斜陀螺

37、y atbe deceived and conclude the following:I.因?yàn)槲镔|(zhì)在“負(fù)”和“正”力學(xué)組成上大體相等，也就是說，由相同的旋轉(zhuǎn)方向相反的陀螺實(shí)體組成，一個人也說第一次被誤導(dǎo)并總結(jié)如下：WRONG: Matter is principally negative and itive in its comition and therefore there would bea cancellation effect with respect to a pivoting motion when an (Obvious) force tilted their respecti

38、ve axes. Therefore, thegyroscopic-actionentity cannot be the cause of the inertia effect.錯誤的結(jié)論：物質(zhì)的組成主要是“負(fù)”和“正”，因此當(dāng)一個（可見）力傾斜它們各自的軸時，相對于旋轉(zhuǎn)運(yùn)動，將有一個“抵消效應(yīng)”。J. Lets examine the CORRECT:J.讓檢查正確的結(jié)論：Consider the factt (Obvious) Force = Inertia Mass X Acceleration. The mt appearshe equation F = ma is ameasure

39、of the inertia of the body. (See Section 30-A.) Therefore, in reality, the inertia effect is relative to the speed of themass. If the mass has no speed then it can have no acceleration. During acceleration the mass simply has varying speeds.考慮事實(shí)（可見）力=慣性質(zhì)量*加速度。“方程式 F = ma 中的 m 是物體慣性的度量”（看圖 30-A）。因此，實(shí)

40、際上，慣性效果關(guān)系到物質(zhì)的“速度”。如果物質(zhì)沒有速度，那么它沒有加速度。在加速過程中物質(zhì)有變化的速度。Hence, one can conclude from the factst any mass having speed also has inertia.因此，可以總結(jié)出事實(shí)，任何有速度的物體也有慣性。K. If one simultaneously shoots a bullet and drops another bullet (of equal mass to thebullet) from the sameition,they will both collide with the

41、Earthrface at the same instant. (See Figure 30-K.) WRONG: Because thegravity effect (Obvious Force) caused the two bullets with equal masses to simultaneously collide with the Earthrface, itcan be concludedt the inertia effect of the two bullet-masses did not change at any time.K.如果一個人在同一位置同時射出一個和拋出

42、別一個（和第一個質(zhì)量相同），它們將在同一瞬間碰到同時碰到地面，這可以總結(jié)為兩地面。（看圖 30-K）這是錯誤的結(jié)論:因?yàn)橹亓πЧ梢娏Γ┮饍蓚€同質(zhì)量的個的慣性效果從來就沒變過。L. Consider the following experiment which will demonstrate why the aboveis wrong:L.考慮下面的實(shí)驗(yàn)，證明為什么上面的結(jié)論是錯誤的：Construct a configuration as dcted in below in Figure 30-L. Place two bullet traps equidistant fromof t

43、he gunbarrel. With the assistance of an electric eye (which can react fast enough) and an appropriate mechanical device, the twotraveling bullets would be simultaneously deflected at a right angle to their respective trajectorieso traps 3 or 4. In addition,a prere gauge could be connected to the mec

44、hanical device employed to deflect the bulletso the two traps. The pure ofthe gauge is to measure the exact (Obvious) optraps.ing force required to deflect the two bullets of equal masseso the two構(gòu)建一個如圖 30-L 描繪的裝置。放兩個“捕獲”裝置在槍管后。在電子眼（足夠靈敏）和一個合適的機(jī)械裝置的幫助下，兩個運(yùn)動的將同時在垂直軌道進(jìn)入捕獲器 3 或 4。另外，一個壓力計(jì)將連接到用來偏移到兩個捕獲器

45、的機(jī)械裝置。壓力計(jì)的目的是測量精確（可見）的將兩個偏移到兩個捕獲器的“反”作用力。It should be obvioust to deflect the two bullets will require considerably more (Obvious) force with respect to the massof trap mechanism 3n for the mass of trap mechanism 4.明顯的，捕獲器 3 需要遠(yuǎn)遠(yuǎn)多于捕獲器 4 的（可見）力來偏移。QUESTION: Why the difference in force?問題：為什么會有不同的力？AN

46、SWER:The differencehe fordemonstrated by the two trap masses is a result of the additional speed added tothe comition of their masses. This additional speed is also added to the natural speed of the basic building entity of eachmass: the gyroscopic-action-particle.回答：兩個不同的力是額外的速度加到它們的質(zhì)量上的結(jié)果。額外的速度同樣加

47、到每個物體基礎(chǔ)組成實(shí)體陀螺子的“自然”速度上。Because the mass of trap 3 had greater speed added to its massn the mass of trap 4, the test instruments would indicatet the mass of trap 3 has a greater inertia effectn the mass of trap 4.因?yàn)椴东@器 3 中的比 4 中的有更快的速度，測試裝置將3 中的比 4 中的有更大的慣性效果。ADDITIONAL PROOF:When the additional spee

48、d is removed (i.e., the mass is stopped), then the two bullet -massesdemonstrate equal inertia effects.額外的證明：當(dāng)額外的速度去除后（如，物體），兩個有相同的慣性效果。M. Consider the factt motion (energy) is the natural se of the Universe, andt the absence of motion (lack ofspeed) of Obvious Mass is the unnatural se of the Univer

49、se.M.認(rèn)識到運(yùn)動（能量）是宇宙的“自然”狀態(tài)，（無速度）的可見物體是宇宙的“不自然”狀態(tài)。Energys motion (speed) is always present, even when such energy -in the form of gyroscopic particles moving at thespeed of light and spinning at the speed of light - is combined to form an Obvious mass whiacroscopically has an apparentabsence of motion.

50、 However, an observer who was microscopically placed insideenergy of all matter - the gyroscopic-action-particle -moving at very high speeds!t Obvious mass would observe the basic能量的運(yùn)動（速度）總是存在的，即使當(dāng)能量-陀螺子形式以光速運(yùn)動并以光速旋轉(zhuǎn)-組成可見物質(zhì)的形式，宏觀上是的。然而，微觀上觀察者可以看到可見物質(zhì)“”組成物質(zhì)的基礎(chǔ)能量-陀螺子-在以非常高的速度運(yùn)動。The natural, inertia ef

Such charges o

52、nly produce an equaling counter force which prevents an (Obvious) mass from behaving as asingle, conventional gyroscope. Moreover, the speeds of those infiniy small masses still exist and the existence of such speeds is proven via the observed, inertia effect of an (Obvious) mass.組成物質(zhì)的“負(fù)”和“正”電荷沒有抵消無

53、限小的陀螺子質(zhì)量的速度。這種電荷只產(chǎn)生相等的“反向力”，（可見）物體像單獨(dú)的陀螺儀一樣運(yùn)動。然而，這此無限小的物質(zhì)的速度依然存在，這種速度的存在可以通過可見的慣性效果證明。N. To further sensitize the reader to the factt one cannot take the ingeniouion of the gyr-ition of matter franted, conduct the following test: (GYROSCOPIC PLANES shown below.)N.對于更敏感的讀者不能認(rèn)為組成物質(zhì)的陀螺子的靈敏運(yùn)動理所當(dāng)然，在下面的實(shí)驗(yàn)
