Yes Fleet Captain, a tractor beam is a non-Newtonian device which creates an attraction between the emitter and the target. The target is always drawn toward the emitter, irrespective of mass, because the beam does not actually transmit a force across space. It functions similarly to the warp drive, manipulating space-time at the target's position.
It is possible to transmit certain sorts of signals from the target back through the tractor to the emitter.
