momentum conservation law
Description:
The momentum conservation law defines the consistency of total momentum in a closed system. In an ideal impulse scenario, the momentum $\overrightarrow{p}$ before the impulse is equal to $\overrightarrow{p}'$ after the impulse. The interaction between two bodies as they collide with each other (with the relevant Velocity $\overrightarrow{v}$ and mass m) does not result in a loss of momentum. The following applies: ${{m}_{1}}{{\overrightarrow{v}}_{1}}+{{m}_{2}}{{\overrightarrow{v}}_{2}}={{m}_{1}}\overrightarrow{v}{{'}_{1}}+{{m}_{2}}\overrightarrow{v}{{'}_{2}}$. Interactions with the environment such as Friction effects are discounted, as the system in question is closed. This is a theoretical method of approach, but it does make complex systems calculable. In practice, it is not possible to create a completely closed system.

动量守恒定律
Description:
动量守恒定律是指一个封闭系统的总动量保持不变。 在理想的冲击情况下，系统冲击前 $\overrightarrow{p}$ 后 $\overrightarrow{p}'$ 动量不变。两个物体的互相碰撞（以一定的速度 $\overrightarrow{v}$ 和质量m）不会导致总动量的减少。 适用以下公式: ${{m}_{1}}{{\overrightarrow{v}}_{1}}+{{m}_{2}}{{\overrightarrow{v}}_{2}}={{m}_{1}}\overrightarrow{v}{{'}_{1}}+{{m}_{2}}\overrightarrow{v}{{'}_{2}}$ 。 由于名义上系统是封闭的，所以当系统与外界接触时，例如在摩擦力的作用下系统动量将减少。虽然这只是理论研究方法，但它可应用于复杂系统的能量计算中。 实际上，完全封闭的系统是不存在的。 两个球体碰撞的动量守恒
