Artificial gravity kept the landing party comfortably secured in their seats.

So far, the artificial gravity was keeping her steady as she entered the stratosphere.

The centrifugal gravity had kept her strong, and it had no time to struggle.

Centrifugal spin provided artificial gravity, one G to keep everybody comfortable.

The gravity kept increasing, more and more, until it had reached Starplex's shipboard standard.

He got to his feet, thinking that at least the lighter gravity was keeping his knees from buckling.

I appreciate it when, though I know the earth spins at more than a thousand miles an hour, gravity keeps my futon in place.

As the ride reaches full speed, gravity keeps the riders in place even when the ride is on a 90-degree angle.

If the initial velocity is fast enough, gravity will keep causing the velocity to decrease without ever stopping the object.

Fortunately, gravity keeps much of the stomach acid away from this doorway.
