There are several conservation laws in physics; each one states that something doesn't change in a closed system. Some of the things that won't change (that are conserved) are:* Momentum * Rotational momentum * Mass * Energy * Electric charge
A closed system
According to the law of conservation of momentum which states that in a closed system momentum before collision is equal to the momentum after collision.
That means that a quantity, called "momentum", can be defined, and that this quantity does not change over time. In any collision, for example, the momentum (which is defined as mass x velocity) of individual objects can change, but the total momentum does not change. Please note that since velocity is a vector quantity, momentum is also a vector quantity.

Several things in the Universe are believed to remain constant; we talk about "conservation laws". For example:The total amount of energy in a closed system is conserved.The total amount of mass in a closed system is conserved.The total momentum in a closed system is conserved.The total rotational momentum in a closed system is conserved.Total electric charge.Several other numbers that are mainly used in quantum mechanics.Ultimately, a "closed system" includes the entire Universe. But it may also refer to a smaller system, as long as no energy (or mass, or momentum, etc.) is transferred to or from outside objects.
A closed system
In a closed system with no external forces acting upon it, the momentum of the system is constant.
According to the law of conservation of momentum which states that in a closed system momentum before collision is equal to the momentum after collision.
An angular momentum is the vector product which describes the rotary inertia of a system around its axis and is conserved in a closed system.
the principle that the total linear momentum in a closed system is constant and is not affected by processes occurring inside the system.
Conservation of linear Momentum is independent of the coordinate system. It does not matter what coordinates are used. In a closed system, i.e. no external forces, momentum is conserved
That means that a quantity, called "momentum", can be defined, and that this quantity does not change over time. In any collision, for example, the momentum (which is defined as mass x velocity) of individual objects can change, but the total momentum does not change.

An open system is a system which can be affected by external factors. Energy of the system can be altered, total momentum, charge, etc. In a closed system, energy, mass, momentum, charge and other properties are conserved.
You say that momentum is conserved. This is always the case, if the system has no interaction with anything outside the system.
Total momentum in an isolated system does not change. The law of physics. The law of conservation of momentum explains that momentum is neither lost of gained. That means that there is a quantity, called momentum, that is conserved.
