  The classical double copy relations establish correspondence between exact
gravity solutions and their counterparts in biadjoint and gauge theories. In
this work, we investigate a peculiar case of double copy relations arising in
exact solutions of the scalar gravity equation, relating static spacetime
geometry to the Komar density distribution. We use a scalar-restricted static
metric ansatz to isolate the degree of freedom governed by the linear equation
for the zeroth copy. The corresponding metric solutions are interpreted as
describing gravity without self-interaction, based on the Komar density
distribution. The single copy of these metrics reveals direct correspondence
between the sources of scalar gravity and electrostatics. Furthermore, this
correspondence persists even at the level of particles, their motion being
governed by the same non-relativistic expressions with respect to the
background space. These and other results lead us to conclude that scalar
gravity is the manifestation of double copy relations encoded in the structure
of general relativity.
