The tidal acceleration moves water about two meters in six hours.
The free fall acceleration moves water two meters in about 0.4 seconds.
The force is related to the square of the ratio of those times. That's gives a measure of the low-down scale of tidal forces.
If you are in genuine free-fall though (and not the term as bastardized by parachutists), then the presence of tidal forces is the only thing that reveals the presence of gravity.
