动量守恒定律（conservation of momentum）是物理学中的核心原理之一，指在一个孤立系统中，若不受外力作用或外力矢量和为零，系统的总动量将始终保持恒定。该定律是牛顿力学三大定律的延伸，适用于宏观与微观尺度，包括碰撞、爆炸、火箭推进等多种物理现象。
动量守恒成立需满足两个条件：
此时，系统内各物体相互作用（内力）不会改变总动量，数学表达为：
$$ sum mathbf{p}{text{初始}} = sum mathbf{p}{text{终}} $$
其中动量$mathbf{p}=mmathbf{v}$为矢量，方向与速度一致。

动量守恒定律（Conservation of Momentum）是物理学中的核心定律之一，其核心内容为：在一个孤立系统中，若没有外力作用，系统的总动量始终保持不变。以下是详细解释：
动量守恒分为线动量守恒和角动量守恒：
动量守恒是牛顿第三定律（作用力与反作用力）的推广。例如，两物体相互作用时，它们的动量变化等值反向，总动量不变。
动量守恒源于空间平移对称性（物理规律在空间各处相同），属于诺特定理在经典力学中的体现，与能量守恒（时间平移对称性）、角动量守恒（空间旋转对称性）共同构成物理学守恒定律的基石。
