nejnimpetu


impetu
fu'ivla x_{1} is the momentum [vector] of x_{2} in frame of reference x_{3} x_{1} can be a vector, e.g. fourvector. Might be pretty general in its semantic scope ("quantity of movement"); at the very least includes both Relativistic (fourvector) and Newtonian (threevector) momentum (resp.: nejnimpetu, sirmpetu); might also encompass angular momentum (cnampetu, typically threevector). See also nejni, nejnimpetu, sirmpetu, ocnerta, tcelerita, cnampetu


sirmpetu
fu'ivla x_{1} is the [probably spatial] linear momentum [vector] of x_{2} in frame of reference x_{3} Threevector. Technically, the word only implies a linear momentum; spatialness is perhaps implicit but should be specified in tanru for safety. See also: impetu, nejnimpetu, cnampetu, ocnerta.


ocnerta
fu'ivla x_{1} is a physicallyrequired conserved quantity in an ideal closed system such that it is associated with (Noetherian) symmetry/Hamiltoniancommuting observable/deterministic feature/law/property/aspect x_{2}, applicable under conditions/in universe/in metaphysics x_{3} See also: impetu, nejni, nejnimpetu, cnampetu, dikca, eldicka'u, kuardicka'u, tcelerita.
