That means that there is a quantity, called momentum, that is conserved. Momentum is defined as the product of mass times velocity. If you add (product x velocity) for several items, or particles, before and after a collission for example, the total you get will not change.
Note that, since velocity is a vector quantity, so is momentum, so if your items move in more than one dimension, you have to use vector addition.
if external force acting on a system of a bodies zero than the total linear momentum of bodies before collision after collision will be same.
it states,''in the absence of external force , linear momentum of the system remains constant.''
No, because the conservation momentum principle is only valid when none force is applied. And here you have the gravity force.
After a collision,The initial momentum of a system is equal to final momentum. m1V1=m2V2
energy transfer through transferring momentum. karim khan
The conclusion for a lab about the conservation of linear momentum is exactly that. Linear momentum is conserved. Momentum p = m*v is a product of mass and velocity. The larger the mass or faster the velocity, the higher the momentum. It takes prolonged force to stop it. Also, if a closed system exists that is not affected by dissipative forces, the total momentum of the system will remain. In a collision between two objects, momentum is conserved.
You have more or less described a law of physics known as conservation of momentum, which is not the same thing as the law of universal gravitation. The law of universal gravitation describes the way mass attracts other mass, and the law of conservation of momentum tells us that momentum is neither created nor destroyed. These two laws are not connected.
it works on the basis of conservation of linear momentum
the principle that the total linear momentum in a closed system is constant and is not affected by processes occurring inside the system.
pocom = principle of conservation of momentum
linear momentum. A rocket works by expelling gases from one end at a very high velocity. The escaping gases have a very high speed and this with their mass translates to a very large momentum. Due to the principle of conservation of momentum the body of the rocket is pushed forward. If both the momentum of the gases as well as that of the rocket are added the sum is zero.

In an isolated system the total momentum of a system remains conserved. For example If you fire a bullet from Gun , bullet go forward with some linear momentum and in order to conserve the linear momentum the gun recoils
Yes. As far as I am aware, no exceptions are known.
I don't think it's the law of momentum that's states that. It's the law of conservation that states that energy cannot be created or destroyed, but can change from one form to another. The law of the conservation of linear momentum states that when the vector sum of the external foreces is equal to zero, the linear momentum of that system remains constant.
