No external forces. Objects may bounce off each other, or merge but the total momentum is unchanged even when the total energy changes.
A necessary condition for the conservation of momentum is that there are no external forces acting on the system. This means that the total momentum of the system will remain constant before and after a collision or interaction between objects.
Always. There are no expections to the conservation of momentum.
The conservation of angular momentum in a system can be ensured by making sure that no external torques act on the system. This means that the total angular momentum of the system will remain constant as long as there are no external forces causing it to change.
The conservation of angular momentum and the conservation of linear momentum are related in a physical system because they both involve the principle of conservation of momentum. Angular momentum is the momentum of an object rotating around an axis, while linear momentum is the momentum of an object moving in a straight line. In a closed system where no external forces are acting, the total angular momentum and total linear momentum remain constant. This means that if one type of momentum changes, the other type will also change in order to maintain the overall conservation of momentum in the system.
The momentum of two objects after a collision is explained by the law of conservation of momentum, which is derived from Newton's third law of motion. This law states that the total momentum before a collision is equal to the total momentum after the collision in the absence of external forces.
it works on the basis of conservation of linear momentum
The conservation of momentum states that in a closed system, the total momentum before an interaction is equal to the total momentum after the interaction, as long as no external forces are present. This principle is based on the law of inertia and is a fundamental concept in physics.

When two vehicles collide and come to a stop, the total momentum of the vehicles before the collision is equal to the total momentum after the collision, in accordance with the law of conservation of momentum.
Conservation laws suggest that energy, matter, and momentum cannot be created or destroyed but can only change forms or be transferred between objects. Conservation of energy states that the total energy in a closed system remains constant. Conservation of matter indicates that the total mass in a closed system is constant. Conservation of momentum asserts that the total momentum of an isolated system remains constant in the absence of external forces.
The momentum before and after is the same, due to the Law of Conservation of momentum. Thus if you calculate the momentum before, then you have the after momentum or vice-versa.
There are several conservation laws in physics, and many of them tell an astronomer what is, and what isn't, possible. This can help explain how certain things happen, or even predict what will happen. Among the laws of conservation that are relevant in astronomy are: conservation of mass; conservation of energy; conservation of momentum; conservation of rotational momentum; conservation of charge.
