We show that ultra-light scalar dark matter (fuzzy dark matter) has a quantum
mechanical universal acceleration scale about $10^{-10}ms^{-2}$, which
naturally leads to the baryonic Tully-Fisher relation dynamically established.
Baryon matter at central parts of galaxies acts as a boundary condition for
dark matter wave equation and influences stellar rotation velocities in halos.
This model also explains the radial acceleration relation and MOND-like
behavior of gravitational acceleration found in various type of galaxies
without any modification of gravity or mechanics. This analysis can be extended
to the Faber-Jackson relation.
