does a rocket go faster when it is reaching the sky's edge or when it is taking off from the ground on liftoff?
it's raw speed and/or acceleration? sky's edge near outer space is where there is lower gravity.

think maybe a bottle cap on a wine bottle that explodes? initially starting value, the wine bottle doesn't budge. a little bit of force applied and it EXPLODES OFF!

answers:
Robert J say: The main reason the acceleration increases as a rocket gains altitude is that the fuel is being burnt, so the same engine thrust is working on a lighter and lighter mass.
-
say: Go watch a video on a rocket's take-off, the speed is very low when it first starts to lift off the launching pad.

billrussell42 say: There is no "edge" to the sky. The atmosphere gets thinner and thinner, but never goes to zero. Even at the height of the space station, the atmosphere can be measured. Even at the height of the moon, there are a few air molecules per cubic meter.

The speed of a rocket depends on the force of the engines and the acceleration and air resistance and other factors. It's a complicated formula and depends on the design parameters of the rocket.
