And there beneath it, approaching at a leisurely one-eighth of a gravity acceleration, was Europa's central sea.

And there would be men on board, to rule out ten and fifteen gravity acceleration.

But even he could easily outdo Atkill's best acceleration, since the Prometheus was equipped with the artificial gravity acceleration, which Atkill did not know of, they could not use their repeater, since the shells were rapidly outdistanced.

It works out that I can reach the galactic hub in twenty-one years, ship's time, if I hold myself down to one gravity acceleration.

Most remarkably, they were still within a fifty mile globe of space after the long three gravity acceleration.

The energy density (per unit area) of regular sinusoidal waves depends on the water density , gravity acceleration and the wave height (which, for regular waves, is equal to twice the amplitude, ):

The dancers are subject to real forces up there on stage - gravity, momentum, acceleration - just as we are.

Now the multi-generation ship would become unnecessary as relativity shortens our trip time: four years to the nearest star, twenty-one years to the galactic hub, twenty-eight to Andromeda galaxy - all at one gravity acceleration.

Then comes into action the gravity acceleration with vertical direction.

But that shock was not as great as immediate unsteadiness and nausea; the gravity acceleration was much less than earth-normal.
