This paper is a sequel to the extensive study of warm absorber (WA) in X-rayscarried out using high resolution grating spectral data from XMM-Newtonsatellite (WAX-I). Here we discuss the global dynamical properties as well asthe energetics of the WA components detected in the WAX sample. The slope of WAdensity profile ($n\propto r^{-\alpha}$) estimated from the linear regressionslope of ionization parameter $\xi$ and column density $N_H$ in the WAX sampleis $\alpha=1.236\pm 0.034$. We find that the WA clouds possibly originate as aresult of photo-ionised evaporation from the inner edge of the torus (toruswind). They can also originate in the cooling front of the shock generated byfaster accretion disk outflows, the ultra-fast outflows (UFO), impinging ontothe interstellar medium or the torus. The acceleration mechanism for the WA iscomplex and neither radiatively driven wind nor MHD driven wind scenario alonecan describe the outflow acceleration. However, we find that radiative forcesplay a significant role in accelerating the WA through the soft X-rayabsorption lines, and also with dust opacity. Given the large uncertainties inthe distance and volume filling factor estimates of the WA, we conclude thatthe kinetic luminosity $\dot{E}_k$ of WA may sometimes be large enough to yieldsignificant feedback to the host galaxy. We find that the lowest ionisationstates carry the maximum mass outflow, and the sources with higher Fe M UTAabsorption ($15-17\rm \AA$) have more mass outflow rates.
