what is does the law of conservation of momentum
This entry contributed by Leonardo Motta. Conservation of momentum is a fundamental law of physics which states that the momentum of a system is constant if there are no external forces acting on the system. It is embodied in Newton's first law (the law of inertia). Suppose we have two interacting particles 1 and 2, possibly of different masses.
The law of conservation of momentum states that momentum can neither be created nor destroyed; the total momentum of any closed system must remain the same. Momentum is mass t â¦ imes velocity.
