Actually, centripetal force, which is a constant acceleration toward the center of a circle.
The Z-82 was rushing through space with constant acceleration.
He didn't have the strength to keep breathing under such constant, brutal acceleration.
Each vessel was under power at a constant one-gee acceleration.
He found that it was a constant acceleration - gravity caused things to fall faster each second.
Down he went, his rate of acceleration constant as he kept some pressure on the brakes.
This then led to non-uniform time in relation to a constant acceleration as the most likely theory.
Even at constant high acceleration, crossing a system can take weeks.
Except for the constant acceleration, they might have been sitting in an ordinary office waiting room.
Zero and constant acceleration brought the charge slowly back into the center of the screen.
