There is an in universe hint of this in ENT 3x10, where the whole NX-01 Enterprise needs a force of 2500 Kilodynes to be pulled from a nebula. Which, if you do the math, results in the whole ship only weighing about 158 kg. Most of the times this is interpreted as a writing error, but could also be the result of some arcane technology such as inertial dampeners or the deflector dish.
