Re: Cause and Effect

Right. And? It would still have to push a mass from immobility into motion, which takes F=ma amount of force. If force F is small, it can only give a tiny little acceleration a to the constant mass m.

That regardless of whether the ship is floating in space or in water. (Although there'd be a tad less friction in space, admittedly.)
