The dynamic visualization of the two-body collision powerfully illustrates that the Law of Conservation of Momentum is a direct consequence of Newton's Third Law (Action-Reaction). As the objects interact, the total momentum of the closed system remains constant, meaning any momentum lost by one object is precisely gained by the other. This conservation is achieved because the internal forces acting between the two objects ($\vec{F}_1$ and $\vec{F}_2$) are always equal in magnitude and opposite in direction. By ensuring the net internal force ( $\vec{F}_1+\vec{F}_2$ ) is zero at every instant of the collision, the system guarantees that the total rate of change of momentum ( $d \vec{p} / d t$ ) is also zero, preserving the total momentum.
