"Get on the acceleration couch," said Marcus as he did so himself.

Wilbur awakened with a start, sitting on the edge of the acceleration diaphragm.

The Ardan missiles were powered for an acceleration of one hundred gravities.

You do not really employ that barbarous method of acceleration?

"All the other Gerns are by now in their acceleration couches," he said.

We'll fall toward it and give the ship all the acceleration she'll take.

The acceleration was marvellous, and wholly in the lines of unity.

When he woke, acceleration had its crushing hand on his chest.

The Lhari ships hit 12 gravities in the first surge of acceleration.

Even so, when they went into Acceleration Two, he felt stinging fear.
