University Physics Third Revised Edition Volume 1 (Paperback)

Accuracy
My primary objective has been to present concepts and principles clearly and correctly. I hope that the physics is free of even subtle misconceptions. In some optional sections I try to deal correctly with topics, such as the work-energy theorem for systems, that are inadequately treated in other texts. Attention is given to details such as the subtle question of signs in the application of Coulomb's law, in Faraday's law, or in Kirchhoff's loop rule for ac circuits. The concepts of emf and potential difference are clearly distinguished. The acceleration due to gravity and the gravitational field strength are given different symbols (although I do not dwell on this distinction).
Writing Style
I have tried to write in a simple, clear, and concise manner. This approach applies as much to the language as to the presentation of the mathematics and the notation used. The examples emphasize the important, or conceptually difficult, steps. Although the coverage is fairly complete, this textbook is significantly shorter than many that have appeared in recent years.
Pedagogy
I focus on central issues and highlight as few equations as possible (in the second color). Special cases, such as the "range formula" in projectile motion, are often discussed in an example and do not appear in the chapter summary. Also, I prefer not to present multiple versions of the same equation. For example, the intensity variation in the double-slit interference pattern appears only in terms of the phase difference (cf>), and not in terms of the angular position (O) or the vertical coordinate on the screen (y).
Questions, Exercises, and Problems
There is a large selection of questions, exercises, and problems. The questions are limited to those that students should find useful in improving their understanding. I avoid questions with no clear-cut answers. The exercises are keyed to the sections, whereas the problems are not. As an aid to students and instructors, both the exercises and the problems are graded according to two levels of difficulty: I and II. The answers to the odd-numbered exercises and problems are given in the text. A solutions manual containing brief solutions for all the exercises and problems is available only to instructors, not to students.
Content and Structure
The text includes almost all the traditional topics in classical physics. The last six chapters cover selected topics in modern physics. Basic material appears in a single-column format, whereas optional sections are in a two-column format. The overall structure is conventional. The discussions of the dot and cross products fit neatly into Chapter 2 but are easily postponed until they are needed. Chapters 15 to 17 on oscillations and waves may be combined with optics for a unified treatment of waves. The dynamics and energy aspects of satellite motion are discussed in Chapters 6 and 8, respectively. These topics may be delayed until Chapter 13 for a unified treatment of gravitation, but, as it stands, the whole of Chapter 13 may be omitted.

準確性

我的主要目標是清晰且正確地呈現概念和原則。我希望物理學中甚至微妙的誤解都能被排除。在一些選修章節中，我試圖正確處理其他教材中處理不足的主題，例如對於系統的功能定理。我特別關注細節，例如在庫倫定律、法拉第定律或基爾霍夫迴路規則在交流電路中的應用中的符號問題。電動勢和電位差的概念被清楚地區分開來。重力加速度和重力場強度使用不同的符號表示（儘管我不會過多強調這種區別）。

寫作風格

我試圖以簡單、清晰和簡潔的方式寫作。這種方法不僅適用於語言，也適用於數學和符號的呈現。例子強調重要的或概念上困難的步驟。儘管涵蓋範圍相當完整，但這本教科書比近年來出現的許多教科書要短得多。

教學法

我專注於核心問題，並盡量少使用方程式（以第二種顏色顯示）。特殊情況，例如抛體運動中的“射程公式”，通常在例子中討論，並不出現在章節摘要中。此外，我不喜歡呈現同一個方程式的多個版本。例如，雙縫干涉圖案中的強度變化僅以相位差（cf>）表示，而不是以角位置（O）或屏幕上的垂直坐標（y）表示。

問題、練習和問題

這本教科書提供了大量的問題、練習和問題。問題僅限於學生在提高理解能力方面有用的問題。我避免提出沒有明確答案的問題。練習與各章節相關聯，而問題則不是。為了幫助學生和教師，練習和問題都根據難度分為兩個等級：I和II。奇數編號的練習和問題的答案在文本中給出。包含所有練習和問題簡要解答的解答手冊僅提供給教師，而不提供給學生。

內容和結構

本書涵蓋了幾乎所有傳統的古典物理學主題。最後六章涵蓋了現代物理學的選定主題。基礎材料以單欄格式呈現，而選修章節以雙欄格式呈現。整體結構是傳統的。對於點積和叉積的討論可以很好地放在第2章，但可以在需要時再進行。第15至17章關於振動和波動的討論可以與光學結合，形成統一的波動處理。衛星運動的動力學和能量方面在第6章和第8章中討論。這些主題可以延後到第13章，以進行統一的引力處理，但目前整個第13章可以省略。
