Coursera 上的物理问题（力学）解决方法课程总结 这门课程是为解决力学问题中与力相关的难题而设计的。课程提供了一个五步技术，帮助学习者系统地解决任何涉及力的物理问题。 课程结构分为三个部分： 第一部分：概述 本部分包含三集视频，总结了五步解题技术，并提供了两个已解答的示例。目的是让学习者对该技术有一个初步的了解。 第二部分：详细讲解 本部分包含六个教学视频，深入讲解了每一步的应用过程，并展示了在不同情境下的应用。课程会详细介绍每一步所需的概念和数学工具（每一步一个视频，外加一个关于向量运算的额外视频）。学习者将掌握如何绘制受力图，如何用数学表达式表示合力，如何进行向量运算，何时以及如何应用牛顿定律等。 第三部分：练习与巩固 本部分提供了八个练习题，供学习者运用五步技术进行实践。在学生有机会独立尝试后，讲师会在白板上进行详细的讲解和纠错。此外，本部分还有一个关于摩擦力的教学视频。 课程背景与目标： 讲师拥有七年的物理家教经验，发现许多学生在解题时虽然能得到正确答案，但对所用概念缺乏深入理解，思维缺乏条理。这在面对从未见过的考题时容易导致恐慌。本课程旨在帮助学生避免这种情况，学会如何着手解决动态问题，即使面对新问题也能找到解题思路。 学习成果： 通过认真学习课程和勤奋练习，学生将不仅仅掌握一些方程，更能学会一套应对高中水平动力学问题的通用方法。这种思维模式也广泛应用于物理学的许多其他领域，对学生的学习大有裨益。 课程水平： 本课程适合高中最后阶段的物理课程，可作为学校教学的辅助工具，并有助于备考各类高中物理考试，如IB物理、A-Level物理、AP物理等。 讲师：Edouard Reny 博士，物理学导师。 备注：本课程配有手动编辑的字幕，方便非母语学习者使用。
Have you ever been stuck when trying to answer a mechanics question involving forces? Maybe you are clueless on how to begin, or maybe you often get stuck at a certain point? Well, this course is there to solve that problem!This course presents a 5-step technique that can guide you through any physics problem involving force. It is structured in 3 sections.The first three episodes contain a summary of the 5 steps and 2 solved examples. The goal of this first section is to for you to get an overview of the technique before diving into the details.The second section consists in 6 lesson videos. The process of applying each step is presented in detail and in various situation. The conceptual and mathematical tools required to carry out each single step is also presented (1 step = 1 video + 1 extra video about the manipulation of vectors). You will learn here how to draw a free body diagram, how to express a resultant force mathematically, how to manipulate vectors, when and how to apply Newton's Laws etc…The third section is your play-ground! You will find 8 exercises for you to train your skills in applying the 5-step technique to solve physics problems. After giving you a chance to solve each question yourself, the presenter carries out a detailed correction on the white board. This section also contains a video lesson about mechanical friction forces.I have been a private teacher for 7 years now, helping every year, dozens of students with their study of physics. One observation I can report is that many students manage to get by a mechanics problem, and even find a correct numerical solution, without truly understanding the concepts they used, and without any structure to their thinking…The problem shows up the day of the exam when confronted to an exercise they have never seen before… Exam day can then easily turn into panic day. This is why I produced this course, to avoid such a situation.If you follow the course seriously and work on the exercises diligently, you will learn much more than just a bunch of equations. You will learn how to approach any dynamic problem (at the high school level) and thus learn how to begin the resolution process when confronted to a new question.When this approach becomes second nature to you, you will realize that Physics is actually pretty easy to handle: the patterns of thinking presented in this course are commonly used in many areas of physics, and could be very useful to you in your studies.The level of this class corresponds to the last years of High School Physics Programs. This makes it an ideal tool as support for the lessons you get at school, and to prepare any High School Diplomas in Physics, like for example IB Physics, A-Level Physics, AP Physics etc.I hope you enjoy the course and wish you a productive study,Edouard Reny, PhD, Tutor in Physics.Note: This course comes with manually edited captions. So even if you are not a native english speaker, you can still make the most of this course!
