Rocket fuel (called propellant) requires a lot of energy to produce the thrust necessary to move a space-bound vehicle beyond the pull of Earth's gravity. The NASA Space Shuttle was launched into space by the use two re-usable solid rocket motors, or RSRMs. Their propellant was a solid rocket fuel and when it burned, it caused a controlled explosion directed out the nozzle, causing enough force to move the Shuttle and the External Tank into low Earth orbit.

thrust that is greater than earth's gravity
Physics.
Rocket emits particles backward with great force. This means that there is also a force in the other direction, which pushes the rocket forward. Also apparent from conservation of momentum.
newton's second law
The engine was revved up, it rolled and gained lift then suddenly it was in flight.
