text: Conservation of momentum, general law of physics according to which the quantity called momentum that characterizes motion never changes in an isolated collection of objects; that is, the total momentum of a system remains constant.
text: During launch, the downward momentum of the expanding exhaust gases just equals in magnitude the upward momentum of the rising rocket, so that the total momentum of the system remains constant—in this case, at zero value.
text: In physics and chemistry, the law of conservation of momentum (or more precisely, the law of conservation of linear momentum) states that the total momentum of an isolated system remains constant.
text: —the total angular momentum of a closed system remains constant.
text: Hence, angular momentum can be exchanged between objects in a closed system, but total angular momentum before and after an exchange remains constant (is conserved).
text: Thus with no external influence to act upon it, the original angular momentum of the system remains constant.
text: Because angular momentum is the product of moment of inertia and angular velocity, if the angular momentum remains constant (is conserved), then the angular velocity (rotational speed) of the skater must increase.
text: In other words, the total momentum of A and B together remains constant.
text: Total momentum of a system remains constant,
text: Or this is more correct: "In an isolated system (i.e. provided no external force acts), the total momentum of the system remains constant.
text: This means that even though the momentum of A and B can increase or decrease (or change direction), the total (vector) momentum of both A and B must remain constant.
text: The law of conservation of linear momentum states that the total momentum of a system of particles remains constant, so long as no external forces act on the system.
text: Equivalently, one could also say that the total momentum of a closed system of particles remains constant.
