Very soon they left the entire system that included the planet Earth behind, accelerating to a velocity his mind was not equipped to conceive.
My pod's drives are accelerating me to a velocity of 1500 kph, straight toward the surface.
All involve spinning the disc to give it gyroscopic stability, and accelerating its mass to a certain velocity.
The afterburner increases thrust primarily by accelerating the exhaust gas to a higher velocity.
To escape from the Moon's gravitational field, a sample must be accelerated to a velocity above 2.4 kilometres per second.
Because of the huge mass difference, electrons are accelerated to a much higher velocity than ions.
But when an ordinary particle is accelerated to a high velocity, up close to light speed, relativity takes over.
The shell is accelerated to a high velocity in a very short time by the rapid generation of gas from the burning propellant.
In the forthcoming shot, the Livermore gun is expected to accelerate an 11-pound projectile to a velocity of about 9,000 miles an hour.
The electron has a much higher charge/mass ratio and so is accelerated to a higher velocity than the ion.
