課程大綱
人類對於周遭事物，如何隨時間與環境而變化，都充滿好奇心。我們要如何用物理學推敲出萬物的變化，或基於系統性的觀察而提出新的想法，這就是普通物理（一）的課程目標。那要如何養成研究問題的邏輯與方法呢?
Human are curious about how things changed with the times and environment. How can we use physics to figure out the change of things or promote new ideas based on systematic observation? How can we develop the logics and method of doing research? These are the course purposes of General Physics.

Description of the course
人類對於周遭事物，如何隨時間與環境而變化，都充滿好奇心。我們要如何用物理學推敲出萬物的變化，或基於系統性的觀察而提出新的想法，這就是普通物理(ㄧ)的課程目標。那要如何養成研究問題的邏輯與方法呢?本課程以牛頓提出的力學為例，除了學習力學定律之外，也鼓勵同學探討牛頓提出這些理論的原因，同時思考章節之間的關聯性，例如在牛頓的向量力學架構下，已經可以解釋物體的運動，為何還需學習新的能量概念等等。
課程內容涵蓋基礎牛頓力學、功與能量概念，在熟悉單粒子運動後，將建構簡單的多粒子系統（剛體）所遵守的物理規則（轉動運動），基於以上的物理知識，詳細探討日常生活中常見的物理現象，如重力、固體與流體、振盪、波動等。同時也將探討愛因斯坦為何會提出不同於牛頓力學的特殊相對論，以及在特殊相對論中架構下，為何在不同慣性座標系的觀察者們，對時間、空間的認知會有所不同。
We are all curious about how nature works. In order to better grasp the fundamental rules that govern our daily life experiences, this course – General Physics (I) – aims to develop students’ abilities in logical reasoning and scientific problem solving. How do we achieve that goal? For example, we will learn Newton’s laws of motion and gravity in this course. The physics of these laws are important, but how Newton and other scientists discovered (or what motivates them to discover) these laws are equally important as well. In addition, we will learn their logical reasoning processes and systematic approaches to tackle problems. Furthermore, it is crucial to make connections between physics topics and form your own understanding of each topics. For example, since Newton’s laws of motion are sufficient to solve mechanics problem, why do we need to introduce the concept of energy to solve the same mechanics problem.
This course will cover Newton's laws of motion and the concept of work & energy. After fully understand the motion of single particle, we then construct a simple many-particle system (Rigid Body), and explore the physical laws it follows (Rotational Motion). Based on the understanding of motion of single particle and many-particle systems, we will discuss the physical phenomena occurred in our daily life, such as gravity, solid & fluid, oscillations and waves. Moreover, we will talk about why Einstein proposed special relativity despite success of Newton’s laws of motion in classical mechanics. Within Einstein’s framework of special relativity, we will demonstrate why observers have different perspectives on time duration and spatial length in different inertial reference frames?
