Continuity equations more generally can include "source" and "sink" terms, which allow them to describe quantities that are often but not always conserved, such as the density of a molecular species which can be created or destroyed by chemical reactions. In an everyday example, there is a continuity

Current is the movement of charge. The continuity equation says that if charge is moving out of a differential volume (i.e., divergence of current density is positive) then the amount of charge within that volume is going to decrease, so the rate of change of charge density is negative. Therefore,

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
