The law of conservation of momentum states that the total momentum of two colliding bodies is constant if the collision takes place in a confined or isolated system meaning that no external force acts on the bodies except the force due to the collision.This in general means that "total initial momentum of the two colliding bodies=Total final momentum of the two colliding bodies"

Momentum is linearly defined as the product of mass and velocity of moving mass.
If the mass stays constant during the motion and velocity does not change ,then momentums stays the same.
If a mass structure changes with velocity during the motion momentum changes accordingly.
If a mass moves with constant momentum,then it means that for a changing decreasing mass velocity has to increase to conserve momentum.
Hence linear momentum conservation is not conserved per Relativity theory.Since Einstein Relativity theory indicates mass increase with velocity increase.

Therefore the law of conservation of momentum applies only in a conservative closed system.
It means that in a collison(interaction between two masses) no energy escapes betwen the two systems.

IN the Case of atom structure where the electrons rotate around the nucleus of the atom the angular momentum is self regulating.Angular momentum in an atomic structure is a constant.
This stems out of Niels Bohr angular momentum of the equation as follows.
h =M x Vx 2 pi x R
Angular momentum is measured as energy time.
where M=electron mass value is the Radius wich changes with velocity per orbit number
V = velocity at that particular orbit of the electron
R =radius vector of the electron orbit.
Here The law of momentum conservation applies .
Its states no matter what the status quo of the electron its momentum is constant.

In a closed system, when there is change in momentum between the interacting bodies, the total momentum remains constant.

For rotational motions the angular momentum is conserved.

Kinetic energy is a form of energy. Since energy can neither be created nor destroyed, only converted from one form to another, then the total momentum of a system before an event will be the same as the momentum after an event, if the kinetic energy does not change in the interaction. If some kinetic energy is converted into another form, such as heat, then the total energy after the event will be the same as the total energy before.

its the same as the conservation of energy or mass...the momentum gets freaking conserved
