tcelerita
fu'ivla x_{1} (number; default: 1) is the physical speed supremum (for objects of positive masses)/celeritas/c_{0} expressed in units x_{2} (default: in terms of natural parameter c_{0}; id est: unitless/dimensionless and equal to 1) in (paradigm/system of) physics x_{3} (default: this, our actual. physical universe and reality); In the Newtonian model, for any finite nonzero units of spatial length and temporal duration, c0 is infinitely large. In the modern Relativistic/Einsteinian paradigm of physics, c0 is a finite positive number for any finite nonzero units of spatial length and temporal duration; thus, in such cases, we can set it equal to 1 (begin measuring in terms of percentage of c0) and gain scaled Relativistic results; by Maxwellian electromagnetism, c0 = 299792458 m/s. Notice the lack of reference to the speed of light and of media through which the wave/particle propagates. This is a physical constant of a universe; any entities of zero mass in a universe will propagate at c0 in an ideal perfect vacuum/classical free space  we just happen to name three such entities "light", "gravitation", and "the strong nuclear force".

fu'ivla x_{1} is Avogadro constant N_{A} [ approximately equal to: 6.02214129(27)×10^{23} mol^{−1}], expressed in units x_{2} in paradigm/system/metaphysics/universe x_{3} (default: this, our actual, physical universe) See also plankexu, tcelerita, gravnutnoia, boltsemaku, ocnerta, molro, kamre


gravnutnoia
fu'ivla x_{1} is Newton's constant of universal gravitation/G/big G [approximately equal to: 6.67×10^(−11) N·(m/kg)^2 ] expressed in units x_{2} (default: unitless/dimensionless and equal to 1) in paradigm/system/metaphysics/universe x_{3} (default: this, our actual, physical universe) See also: plankexu, tcelerita, boltsemaku, avgadro, 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.


boltsemaku
fu'ivla x_{1} is the Boltzmann k_B constant linking energy with temperature [approximately equal to: 1.380 6488(13)×10^{−23} J/K], expressed in units x_{2} (default: unitless/dimensionless and equal to 1) in paradigm/system/metaphysics/universe x_{3} (default: this, our actual, physical universe) Introduced by Planck (along with "h", his own eponymous constant); named after Boltzmann who nonetheless laid the foundation for research into such affairs.

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


plankexu
fu'ivla x_{1} is the elementary unit (quantum) of angular momentum/half of Planck's reduced constant [id est: hbar/2 = h/(4 pi)] expressed in units x_{2} (default: unitless/dimensionless and so that it is equal to 1) in paradigm/system/metaphysics/universe x_{3} (default: this, our actual, physical universe) This unit is not equal to hbar itself, but half thereof; it is equal to the absolute value/magnitude of magnetic quantum number of an electron. In our world and in SI units, this quantity is approximately equal to: 5.27285863 * 10^{35} (m^2)*kg/s. See also gravnutnoia, tcelerita, boltsemaku, avgadro, ocnerta, paulcna.
