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
first stage: engine of the rocket is put on. second stage: lower part of the rocket splits. then the main part of the rocket enters the space and revolve around the earth.
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.
The velocity of rocket must reach 16x than the gravitational force of Earth to establish an orbit in space.

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.

People can not shoot themselves into space. A person must be an astronaut and receive training, in order to travel to space in a rocket.
