All of the conservation laws listed above are local conservation laws. A local conservation law is expressed mathematically by a continuity equation, which states that the change in the quantity in a volume is equal to the total net "flux" of the quantity through the surface of the volume. The following sections discuss continuity equations in ...
The BBM equation possesses exactly three independent and non-trivial conservation laws. [3] First is replaced by = in the BBM equation, leading to the equivalent equation: =. The three conservation laws then are: [3]
Three conservation laws are used to solve fluid dynamics problems, and may be written in integral or differential form. The conservation laws may be applied to a region of the flow called a control volume. A control volume is a discrete volume in space through which fluid is assumed to flow.
The first law of thermodynamics is a version of the law of conservation of energy, adapted for thermodynamic processes. In general, the conservation law states that the total energy of an isolated system is constant; energy can be transformed from one form to another, but can be neither created nor destroyed.

The laws of physics are invariant with respect to space-translation—for example, a rocket in outer space is not subject to different forces or potentials if it is displaced in any given direction (eg. x, y, z), leading to the conservation of the three components of momentum conservation of momentum. The laws of physics are invariant with ...
