Original sentence: Although each particle on the plot follows a parabolic trajectory, the overall shape of the dust cloud deviates strongly from the parabolic shape.However, the wheels were ejecting the particles with a greatly varying speed, when the rover was moving over deep dust pockets.Note that the simulation does not attempt to mimic the exact shape of the dust cloud, it merely shows that a complex, unexpected pattern may emerge from simple laws.The argument would be plausible were the dust particles ejected with a constant velocity by a source moving with a constant speed
Edited sentence: However, there is a complexity at the phenomenon because the wheels were ejecting the particles with a greatly varying speed, when the rover was moving over deep dust pockets.Video analysis and simulation study needs to be done
