The law of conservation of momentum states that momentum is conserved. This means that if the initial momentum of a system is 50 kg m/s, and
none of the kinetic energy is transformed to any other form, then the final momentum will be
kg m/s.
From the law of conservation of momentum, a system that starts with an initial momentum of 50kgm/s will end up with a momentum of 50kgm/s in its final state.
The law of conservation of momentum states that "in an isolated system, momentum is neither created nor destroyed but transformed from one form to another".
From this law, the starting and ending momentum must be the same.
