The volumetric energy density of an aetheric beam ([[Mass and inertia|"Mass and inertia", 1]]):
:<math>w=\rho v^2\label{energy_density}</math>
The absorption of this energy by the surface of area <math>S</math> makes a work by the force <math>F</math> on the path <math>\Delta L</math>:
:<math>A=wS\Delta L=F\Delta L\label{aether_work}</math>
The total pressure of an aetheric beam is the volumetric density of its energy:
:<math>P=\frac{F}{S}=w=\rho v^2\label{beam_pressure}</math>
According to the [[Matter|material particle]] model, a non-magnetic surrounding aether or the space is pressing on a particle with the particle beam pressure. Similarly to the beam pressure, this pressure is the average energy density of a particle ([[Mass and inertia#Eq-11|"Mass and inertia", 11]]) :
:<math>P=\frac{E}{V}\approx\frac{1}{V}\left(mc^2+\frac{mv^2}{2}\right)=\rho c^2+\frac{\rho v^2}{2}\label{particle_pressure_2}</math>
Introducing the relativistic mass concept, the pressure formula simplifies to:
:<math>P=\rho c^2\label{particle_pressure}</math>
The pressure depends on the particle total energy and produces also a potential energy field and a force according to the [[Continuum#Eq-2|Euler’s equation]]:
:<math>\rho\mathbf{\overrightarrow{a}}=-grad\;P\label{pressure_force}</math>
