現(xiàn)代大學物理

內(nèi)容概要

　　本書具有濃厚的現(xiàn)代氣息，即把最新發(fā)展的科學技術納入其中，注重介紹經(jīng)典物理知識在高新技術中的應用，并與現(xiàn)實生產(chǎn)、生活緊密聯(lián)系，同時將現(xiàn)代物理學的觀點、概念和方法滲透其中，內(nèi)容豐富，涉及面廣，圖文并茂，語言通俗易懂，既能讓學生在自然清新、情趣盎然的氛圍中開闊眼界，享受物理，又能讓學生感受到經(jīng)典物理在21世紀仍然煥發(fā)著勃勃生機，生活中到處都有物理，學習物理知識很有用，從而使物理知識的學習有的放矢。本書的這些鮮明特色對提高學生學習的積極性和主動性，培養(yǎng)學生科學的思維能力和創(chuàng)新能力具有重要作用。
　　本書主要內(nèi)容有力學、圓周運動及轉動、碰撞與波、電學、磁學、光學、相對論和量子物理等。本書部分章節(jié)（如經(jīng)典部分的第12章，近代部分的第39章、第40章）與國內(nèi)外許多教材相比內(nèi)容偏深。
　　本書為高校理工科各專業(yè)學生的大學物理雙語教學教材。因書中包含有豐富、實用的各類素材，所以也可作為廣大物理教師非常好的教學輔助資源或參考書。

章節(jié)摘錄

版權頁：   插圖：   1.11 In Europe, cars'gas consumption is measured in liters per 100 kilometers． In the United States, the unit used ismiles per gallon． a）How are these units related? b）How many miles per gallon does your car get if it consumes 12.2 liters per 100 kilometers? c）What is your car's gas consumption in liters per 100 kilometers ifit gets 27.4 miles per gallon? d）Can you draw a curve plotting miles per gallon versus liters per 100 kilometers ? Ifyes, draw the curve． 1.12 Ifyou draw a vector on a sheet ofpaper, how many components are required to describe it? How many components does a vector in real space havel How many compo nents would a vector have in a four-dimensional world? 1.13 Since vectors in generalhave more than one component and thus more than one number is used to describe them, they are obviously more difficult to add and subtract than single numbers． Why then work with vectors at all? 1.14 IfA and B are vectors speafiedin magnitude-direction form, and C = A + B is to be found and to be expressed in magnitude-direction form, how is this donel That is, what is the procedure for adding vectors that are given in magnitudedirection form? 1.15 Suppose you solve a problem and your calculator's display reads 0.0000000036． Why not just write this down? Is there any advantage to using the scientific notation? 1.16 Since the British system of units is more familiar to most peoplein the Uruted States, why is the international （SJ） system ofunits used for saentific work in the United States? 1.17 Is it possible to add three equal-length vectors and obtain a vector sum of zero? If so, sketch the arrangement of the three vectors． If not, explain why not． 1.18 Is mass a vector quantityl Why or why not? 1.19 Two flies sit exactly opposite each other on the surface of a spherical balloon． If the balloods volume doubles, by what factor does the distance between the flies change? 1.20 What is the ratio of the volume of a cube of side r to tbat of a sphere of radius r? Does your answer depend on the particular value of r? 1.21 Consider a sphere of radius r． What is the length of a side of a cube that has the same surface area as the sphere? 1.22 The mass ofthe Sun is 2-1030 kg, and the Sun contains more than 99％ of all the mass in the solar system． Astronomers estimate there are approximately 100 billion stars in the Milky Way and approximately 100 billion galaxies in the universe． The Sun and other stars are predominantly composed of hydrogen; a hydrogen atom has a mass of approximately 2-10-27 kg． a）Assuming that the Sun is an average star and the Milky Wayis an average galaxy, what is the total mass ofthe universe? b）Since the universe consists mainly of hydrogen, can you estimate the total number of atoms in the universe? 1.23 A futile taskis proverbially said to be “l(fā)ike trying to empty the ocean with a teaspoon．” Just how futile is such a task? Estimate the number of teaspoonfuls of water in the Earth's oceans．
