The meaning of CONSERVATION OF MOMENTUM is a principle in physics: the total linear momentum of a system of particles not acted upon by external forces is constant in magnitude and direction irrespective of any reactions among the parts of the system.

In honor of World Cities Day, which concludes Urban October, this year's theme, "Youth Leading Climate and Local Action for Cities," reflects a growing momentum for sustainable urban solutions championed by local communities and progressive policies. Around the world, cities face intensified demands...
They derive their name from the fact that they describe the conservation of some quantities of interest over time. In computational fluid dynamics (CFD), these quantities are usually mass, momentum and energy. For convenience we always refer to the conserved quantity as the "mass" in this ...
Momentum (both linear and angular) is also conserved.In fact all of these units are conserved:ConservedUnits Mass kg Linear Momentum kg m/s Angular Momentum kg m2/s Energy kg m2/s2Electric charge is also conserved.And many other things are also conserved under special conditions....
Conservation of momentum?I am considering the Euler equations in conservative form and solving the Sod shock tube problem I have written a Godunov finite volume type solver. It solves for density ρ, momentum ρu, and total energy E; therefore, I would expect all of these quantities to be ...

2.2.2 The Balance of Momentum Newton's second law of motion is perhaps the most important statement in the field of dynamics. As is well-known, this states that the rate of change of the momentum of a body equals the sum of the external forces acting on it. To apply this law to a...
Modern society is a ceaseless consumer of energy, and growing demandwon’t stop any time soon, even under the most optimistic energy-efficiency scenario. Although it goes without saying that we must continue to improve energy efficiency in the developed world, the momentum ofpopulation growthand ...
The meaning of CONSERVATION OF ANGULAR MOMENTUM is a principle in physics: the total angular momentum of a system free of external torque remains constant irrespective of transformations and interactions within the system.
