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.

The payload's weight
space shuttle orbiters are launched from the Kennedy Space Center in Florida. They must not only travel the ~250 miles to reach "space", they must accelerate to over 17,000 mph to maintain orbit around the Earth. The shuttle orbiter uses its 3 main engines along with a pair of solid rocket boosters to do this.
A rocket is propelled by its engines to overcome Earth's gravity and achieve enough speed to enter orbit or reach its destination. In space, there is no air resistance or opposing forces to slow it down, allowing it to continue moving forward. To prevent a rocket from falling back to Earth, it must reach a minimum speed known as escape velocity.
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.

Currently any satellite must be launched on a rocket to reach space, though ideas for non-rocket launch exist.
The payload's weight, and the weight of the rocket itself.
They must be launched in to space because there is a better veiw in space than from earth.

Escape velocity is the speed that a rocket must reach to break free from Earth's gravity and enter space. It is the minimum velocity required for an object to overcome the pull of Earth's gravity.

Inertia connects to a rocket by affecting its motion. Inertia is the tendency of an object to resist changes in its motion, so a rocket must overcome this resistance to move and accelerate in space. Rockets are designed to counteract the effects of inertia by generating thrust to push them forward despite the inertia acting against their motion.
