We started out not only twenty-nine days behind them, but also a matter of five hundred thousand light-years of distance. It will take us quite a while to get to their starting-point. I can't tell even that very close, as we will probably have to reduce this acceleration before we get out of the Galaxy, in order to give detectors and repellers time to act on stars and other loose impediments.

The question is simply this: Is there to be a permanent black population upon the continent after slavery is everywhere abolished and no inducement remains to foster its increase? Should this question be answered in the negative, it is evident that a wise policy would look to the best mode of removing that race from these States, by the encouragement and acceleration of emigration.

He would expect guided missiles but he probably wouldn't expect to be attacked by space wagons. Joe said suddenly: "Chief! I'm going to burn a twelve-two. We've got to match velocities coming back. Join me? Three two one." He fired a twelve-two. Twelve seconds burning, two gravities acceleration. It built up his speed away from the Platform to a rate which would have been breathless, on Earth.

Tom opened the valve again and felt the tug of the jets braking his acceleration. He drifted slower and slower, and realizing that he was close to the hull of the ship, he stretched his legs, striving to make contact. Seconds later he felt a heavy thump at the soles of his feet, and within the ship there was the muffled clank of metal boot weights hitting the metal skin of the hull.

"The reorganization of the army, with the acceleration of warlike preparedness, has the advantage that it appeals to the embryonic feeling of national patriotism, and affords a tangible expression of the desire to be on terms of equality with the foreigner.

This link is found in the well-known definition of physical force as a product of 'mass' and 'acceleration' in algebraic symbols F=ma. We will discuss the implications of this definition in more detail later on. Let us first see how it is used as a foundation for the above assertion. The more massive the object, the greater will be the force necessary for accelerating it.

The mere fact that any man should dare to offer them would prove his incompetence to judge. Yet Russia was too vast a force to be treated as an object of unconcern. As inertia, if in no other way, she represented three- fourths of the human race, and her movement might be the true movement of the future, against the hasty and unsure acceleration of America.

The kettle simmered gently on the hob. Every other knife and fork was silent; so was every tongue. Master Gammon ate and the kettle hummed. Twice Mrs. Sumfit sounded a despairing, "Oh, deary me!" but it was useless. No human power had ever yet driven Master Gammon to a demonstration of haste or to any acceleration of the pace he had chosen for himself.

He looked up, his expression peculiar. "A solid-fuel rocket can start off at ten gravities acceleration," he said quietly, "and as its rockets burn away it can go up a lot higher than that. But 4,000 miles is a long way to go straight up. If it isn't launched yet " Mike snapped into a microphone: "Right!" To Joe he said, "Space Platform on the wire." Joe heard an acknowledgment in his headphones.

He touched controls and a monstrous weight pushed him back in his seat. The rocket swung, and lifted, and shot skyward with greater acceleration than before. It went up at a lifeboat's full fall-like rate of climb, leaving a trail of blue-white flame behind it. All the surface of Darth seemed to contract swiftly below him.
