| algebraic equation giving the number dN of particles of a non-quantized system, the components of velocity of which are comprised in the intervals (u, u + du), (v, v + dv), (w, w + dw) respectively: |
N is the total number of particles
m is the mass of a particle
T is the thermodynamic temperature
k is the Boltzmann constant
NOTE – dN/N represents the probability that a particle has its components of velocity within the intervals considered.
