Newton's Third Law of Motion: The mutual forces of action and reaction between two bodies are equal, opposite and collinear. This means that whenever a first body exerts a force F on a second body, the second body exerts a force −F on the first body. F and −F are equal in magnitude and opposite in direction. This law is sometimes referred to as the action-reaction law, with F called the "action" and −F the "reaction". The action and the reaction are simultaneous.
What this means is that when the rocket pushes on the ground, the ground pushes back on the rocket with equal force. And if the rocket is causing enough force on the ground, the force the ground is causing against the rocket will cause lift.
Burning rocket fuel exerts pressure on the rocket nozzle. Note that this happens regardless of whether there is any air for the exhaust to push against. It is simply a matter of expanding gasses which exert pressure.
A rocket is able to lift off because of something called thrust. This means if you apply force to one direction, it will also apply force to the opposite direction.

The Saturn V rocket weighed about 6.2 million pounds (2.8 million kg) at lift-off.
Yea
The name of the background song in the Toyota lift off commercial where some guy lifts off in a rocket is Lift Off. This is a song which is done by Jay-Z and Kanye West.Ê
-- Gravity. -- Thrust of the rocket engines. Slightly after lift-off, as the vehicle begins to pick up some vertical speed, air resistance also appears.
It means when a rocket leaves its launch pad. "Lift Off!"
The pressure needed to lift off a rocket from the ground depends on various factors such as the weight of the rocket, gravitational force, air resistance, and the design of the rocket's propulsion system. Rockets use powerful engines to generate thrust that exceeds the force of gravity, allowing them to lift off. Typically, rocket engines produce millions of pounds of thrust to achieve liftoff.
A rocket takes off by igniting its engines, which produce thrust that propels the rocket upward. The main forces involved in the rocket's takeoff are thrust and gravity. Thrust overcomes gravity, allowing the rocket to lift off the ground and travel into space.
