A rocket's speed at launch is typically zero, as it starts from a stationary position on the ground. The rocket gradually accelerates as it is propelled by its engines, reaching higher speeds as it ascends into space.
—the Saturn v had two stages both parts would burn its engines until the fuel ran out then it would come off the rocket
Yes, the thrust on the rocket remains constant in the absence of gravitational force. Thrust is the force pushing the rocket forward, generated by the propulsion system. It is independent of gravitational force.
Liquid oxygen (LOX) is commonly used as a liquid oxidizer in rocket engines due to its high oxidizing potential and high density. Hydrogen peroxide is another liquid oxidizer used in some rocket engines and propulsion systems. Nitric acid is also used as a liquid oxidizer in certain applications.
The two main types of rocket engines are Solid fuel rocket engines and Liquid fuel rocket engines.
Rocket engines are not air breathing engines and hence they can be propelled into space.
Rocket engine
The Saturn V rocket had five rocket engines in its first stage, called the F-1 engines. These engines were responsible for providing the necessary thrust to lift the rocket off the ground and into space.
Model rocket engines are reproductions of rocket engines that are scaled down to a much smaller size than the real thing. They usually don't do anything and are for display purposes.

A rocket ship takes off by igniting its rocket engines, which produce thrust that propels the ship upward. The force generated by the rocket engines pushes the ship off the ground and into the air, overcoming Earth's gravity. As the rocket ascends, its engines continue to provide thrust to propel it further into space.
