\nThe correct answer is B. The law of conservation of momentum is a direct consequence of Newton’s third law of motion when applied to a system of particles.
\n<\/section>\n
\n– Newton’s third law states that for every action, there is an equal and opposite reaction. If object A exerts a force on object B, then object B exerts an equal and opposite force on object A.
\n– When considering a system of two interacting objects, the forces they exert on each other are internal forces. According to the third law, these internal forces cancel out as a pair ($\\vec{F}_{\\text{AB}} = -\\vec{F}_{\\text{BA}}$).
\n– Applying Newton’s second law ($\\vec{F} = m\\vec{a} = d\\vec{p}\/dt$) to the system, the total internal force is zero. Thus, the rate of change of total momentum of the system due to internal forces is zero.
\n– In the absence of external forces, the total momentum of the system remains constant. This is the principle of conservation of momentum.
\n<\/section>\n
\nNewton’s laws of motion are fundamental to classical mechanics. While conservation of energy, charge, and mass are also fundamental physical laws, the conservation of momentum is the one most directly and explicitly derived from Newton’s third law in the context of interactions between particles.
