Alright, it is mainly the force of gravity. This is because if there was no gravity, you do not heat energy to fire the rocket up.
To reach space, a rocket must overcome the force of Earth's gravity, which pulls it downward. This gravitational force is determined by the mass of the Earth and the mass of the rocket, requiring the rocket to generate enough thrust to exceed the gravitational pull. Additionally, the rocket must also overcome atmospheric drag as it ascends through the Earth's atmosphere. Ultimately, it needs to achieve a speed of around 28,000 kilometers per hour (17,500 miles per hour) to enter orbit.
The payload's weight
When a rocket launches, the thrust of its engines must be greater than the gravitational force acting on the rocket, which is the weight of the rocket. This ensures that the rocket can overcome Earth's gravity and lift off the ground. Additionally, the thrust must also be sufficient to counteract any atmospheric drag during ascent.
Weight refers to the force of gravity acting on the rocket, thrust is the force propelling the rocket upward, lift is the force generated by the rocket's fins to keep it stable, and drag is the resistance encountered as the rocket moves through the air. Weight must be overcome by thrust for the rocket to launch, while lift helps the rocket maintain stability and drag opposes its forward motion. Balancing these forces is crucial for a successful rocket launch.

The law of force and acceleration, described by Newton's second law (F = ma), applies to a rocket launch by illustrating how the force generated by rocket engines propels the vehicle upward. As the engines burn fuel, they produce a thrust force that must overcome the gravitational pull acting on the rocket. The resulting acceleration of the rocket is directly proportional to the net force (thrust minus weight) and inversely proportional to its mass. As fuel is consumed, the mass decreases, allowing for greater acceleration as the rocket ascends.
gravity
Currently any satellite must be launched on a rocket to reach space, though ideas for non-rocket launch exist.
A rocket takes off from Earth by igniting its engines to produce thrust, which propels it upwards against the force of gravity. The thrust generated must be greater than the force of gravity in order for the rocket to overcome Earth's gravitational pull and lift off into space. Once the rocket reaches a certain speed and altitude, it can transition to its intended trajectory.
