A total of 64 ATOMS sources at different evolutionary stages were selected toinvestigate the kinematics and dynamics of gas structures under feedback. Weidentified dense gas structures based on the integrated intensity map ofH$^{13}$CO$^+$ J=1-0 emission, and then extracted the average spectra of allstructures to investigate their velocity components and gas kinematics. For thescaling relations between velocity dispersion $\sigma$, effective radius $R$and column density $N$ of all structures, $\sigma-N*R$ always has a strongercorrelation compared to $\sigma-N$ and $\sigma-R$. There are significantcorrelations between velocity dispersion and column density, which may implythat the velocity dispersion originates from gravitational collapse, alsorevealed by the velocity gradients. The measured velocity gradients for densegas structures in early-stage sources and late-stage sources are comparable,indicating gravitational collapse through all evolutionary stages. Wequantitatively estimated the velocity dispersion generated by the outflows,inflows, ionized gas pressure and radiation pressure, and found that theionized gas feedback is stronger than other feedback mechanisms. However,although feedback from HII regions is the strongest, it does not significantlyaffect the physical properties of the embedded dense gas structures. Combiningwith the conclusions in Zhou+2023 on cloud-clump scales, we suggest thatalthough feedback from cloud to core scales will break up the original cloudcomplex, the substructures of the original complex can be reorganized into newgravitationally governed configurations around new gravitational centers. Thisprocess is accompanied by structural destruction and generation, and changes ingravitational centers, but gravitational collapse is always ongoing.

Feedback from protoclusters does not significantly change the kinematic properties of the embedded dense gas structures
