  In order to investigate how the drag force is affected by translational
symmetry breaking (TSB), we utilize a holographic model in which the background
metric remains translational symmetric while a graviton mass or other fields in
the theory break this symmetry. We calculate analytically the drag force,
considering an asymptotic AdS$_5$ in which parameter $\alpha$ arises from TSB.
This parameter can be intuitively understood as a measure of TSB strength and
we anticipate that non-zero values of it will affect the drag force. In this
asymptotic AdS$_5$ background, we will demonstrate that a decrease in $\alpha$
results in a reduction of the drag force. Moreover, we study the diffusion
constant, which falls with increasing $\alpha$. It will eventually be shown
that at lower values of $\alpha$ or $\mu$ (chemical potential), the transverse
diffusion coefficient is larger than the longitudinal one, and the speed of the
heavy quark has minimal impact on the ratio.
