This isn't a question that is coherent enough to answer. I will answer some variation of what I think you are asking:
If you were to accelerate a planet (or any other object) to speeds approaching the speed of light, the force required would increase the closer you got to the speed of light.
Special Relativity states that as the speed of an object approaches "c" (the speed of light), it's mass approaches infinity. Since Force = (mass) x (acceleration) it follows that if the mass is infinity, then the force required to accelerate it would also be infinity. This is one mathematical formulation that shows that nothing can ever move faster than light.
So the exact opposite of your statement is true. The closer you got to "c", the more force would be require to increase the speed of the planet. The required force would continue to build up until, right at the speed of light, it would be infinite.

No, it would have more and more force since force is measured by the speed of an object times its mass. Actually, according to Einstein's theory of relativity, the mass of an object grows as it nears the speed of light. An object with mass would become infinitely massive at the exact speed of light. That is why nothing with mass, like a planet, can move at the speed of light because infinity is not possible. Thus, the greater the speed and the greater the mass, the more force it has.

If you're pushing it in space, it wouldn't increase in speed or decrease. It would stay continuous unless something affected it's travel. Right?
