吃飽太閒的物理老師 on Instagram: "超越 F=ma：優雅的拉格朗日力學 在高中物理中，我們習慣用牛頓的視角看世界：分析受力、畫出向量、拆解分量。這在處理單一滑塊時很直觀，但一旦面對雙擺或限制在曲面上的粒子，牛頓的「向量迷宮」就會變得寸步難行。這時，1788 年誕生的拉格朗日力學 (Lagrangian Mechanics) 提供了一個更為高維的解答：拋棄向量，擁抱能量。 拉格朗日力學的核心哲學令人著迷：大自然是一個極致的優化大師。它不關心每一瞬間的「推力」，而是遵循「最小作用量原理」(Principle of Least Action)。物體在兩點間的運動軌跡，永遠是讓「作用量」 (Action, S) 達到極值的路徑。 透過定義拉格朗日量 L = T - V(動能減位能)，我們不再需要為正向力或張力等約束力頭痛。利用廣義座標 (Generalized Coordinates) 和歐拉-拉格朗日方程式，複雜的力學問題被轉化為純粹的變分法運算。這不僅是解題技巧的升級，更是物理觀的昇華——它證明了物理定律在座標變換下的不變性，並直接鋪平了通往量子力學 (路徑積分) 與廣義相對
