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
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.
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.

Currently any satellite must be launched on a rocket to reach space, though ideas for non-rocket launch exist.

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.
