本文從愛因斯坦速度變換式、相對論中的牛頓第二定律及普遍的能量守恒定律導出質點組的動量守恒定律。
動量守恒定律（conservation of momentum）是物理學中的核心原理之一，指在一個孤立系統中，若不受外力作用或外力矢量和為零，系統的總動量将始終保持恒定。該定律是牛頓力學三大定律的延伸，適用于宏觀與微觀尺度，包括碰撞、爆炸、火箭推進等多種物理現象。
動量守恒成立需滿足兩個條件：
此時，系統内各物體相互作用（内力）不會改變總動量，數學表達為：
$$ sum mathbf{p}{text{初始}} = sum mathbf{p}{text{終}} $$
其中動量$mathbf{p}=mmathbf{v}$為矢量，方向與速度一緻。
動量守恒源于空間平移對稱性，由德國數學家埃米·諾特定理揭示（參考《理論物理學教程》）。實驗驗證包括氣墊導軌實驗與粒子對撞機數據（參考CERN公開報告）。
動量守恒定律（Conservation of Momentum）是物理學中的核心定律之一，其核心内容為：在一個孤立系統中，若沒有外力作用，系統的總動量始終保持不變。以下是詳細解釋：
動量守恒分為線動量守恒和角動量守恒：
動量守恒是牛頓第三定律（作用力與反作用力）的推廣。例如，兩物體相互作用時，它們的動量變化等值反向，總動量不變。
動量守恒源于空間平移對稱性（物理規律在空間各處相同），屬于諾特定理在經典力學中的體現，與能量守恒（時間平移對稱性）、角動量守恒（空間旋轉對稱性）共同構成物理學守恒定律的基石。
