Answer

The law of conservation of momentum states that the total momentum of a closed system remains constant, provided no external forces act upon it. This can be mathematically represented as:

extmomentumbefore=extmomentumafter. ext{momentum before} = ext{momentum after}.

This principle underscores that in isolation, the momentum of colliding or interacting bodies within the system is conserved.
