newtons three laws

"I. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it." Witch means if somthing is in motion it will continue to be in motion unless something moves or pushes aginst it.

"II. The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector." This means that the more speed somthing gets the more force it will be getting A.K.A (ma)mass and acceleration, that would make it go faster.

III. For every action there is an equal and opposite reaction. so this would mean what ever you do to try and make somthing go faster somthing els will always be working aginst it.
