Is it possible for one to say that an object moving vertically downward can accelerate less than the value of acceleration due to Gravity?

Yes, but only when you are extremely high above the surface of the earth, as the gravitational potential energy decreases, and therefore is less than 9.8m/s/s (if on earth)

If warp speed is possible how would you keep the people from hitting the walls of the ship?
As warp drive is a technology from a science fiction, I guess you could say you would use their technology too to stop people hitting the wall. So you would you "interntial dampeners" which would lessen the effect of inertia on the crew... they would accelerate at the same speed as the space ship no matter how sudden the acceleration is.
The ratio of the earths gravity to the suns gravity?
No meaningful comparison is possible without specifying that the distance from both bodies will be the same at the moment of measurement. If you measured the acceleration due to gravity (or your weight) some distance from the sun, and then measured the acceleration due to gravity (or your weight) at the same distance from the Earth, you would find that the measurement in the vicinity of the sun is about 332,982 times the corresponding measurement at the Earth. It doesn't matter what the distance is, as long as both are the same.
What two motions keep an object in orbit?
An orbit is made possible by an equilibrium, or balance, of forces. Typically, this involves two forces: one of gravitational attraction between the objects and another caused by centripetal acceleration. At a given radius of orbit, a velocity can be found such that these two forces are equal, keeping the object in orbit.

not possible without world-engine
Is it possible to create a space colony?
Yes, it is possible to create a space colony.

yes, yes it is
Is it possible for an object with constant negative acceleration to change the direction in which it is moving?
Sure. Anything you toss with your hand has constant acceleration after you toss it ... the acceleration of gravity, directed downward. If you toss it upward, it starts out with upward velocity, which reverses and eventually becomes downward velocity.
What causes a Pontiac Bonneville to jerk during acceleration?
One of the possible causes of a Pontiac Bonneville to jerk during acceleration is that the car needs a tune up. The engine misfiring can lead it to jerk as you accelerate.
Can a situation exist in which an object has zero velocity and nonzero acceleration?
Imagine throwing a ball upwards. It slows down(negative acceleration), and is eventually brought to a stop for a moment before starting to accelerate downwards. Keep in mind that throughout the entire journey there is a downward acceleration of g(9.81 m s-2) acting on the ball, even at that moment where the ball stopped mid-air. Of course that condition was only temporary, but it is still possible nonetheless.
Is it possible to use a gaming console to accelerate PC hardware?
To my knowledge this is not possible, however there are several external GPUs in development, these could help in the future, depending on what hardware needs acceleration.
Is it possible for a body to have its velocity and acceleration pointing in opposite directions?
Sure. Anything that's slowing down has velocity and acceleration in opposite directions. -- A ball tossed up in the air has upward velocity and downward acceleration. -- A car stopping for a red light has forward velocity and backward acceleration.

Is it possible that there is a non-zero acceleration but with a speed of value zero?
Not with any sensible definition of "acceleration" and "velocity." You CAN accelerate an object and have it end up at zero velocity. But, if the acceleration remains a non-zero number, then the velocity can NOT remain at zero. Your question is like asking, "Can the value of a quantity change, but also remain the same?"
Is it possible for a body with zero velocity to have non-zero acceleration?
Yes, but only for a single instant in time. When you throw a golf ball or a rock straight up, it has the constant downward acceleration of gravity from the moment it leaves your hand, but its velocity is certainly not constant. The velocity steadily decreases until the peak of the toss, and then it switches from upward to downward velocity. At the very peak, the velocity is zero for an instant.

not possible

How much force would be required to accelerate the car at a rate of 3 sec?
"3 second" isn't a rate (an acceleration), it's a time.The force can be calculated by Newton's Second Law: just multiply the mass by the desired acceleration.
