Rockets, the fire and gas propelled out the bottom make it rise.
The space shuttle experienced about 3 G's (3 times the force of Earth's gravity) during launch. This force occurred as the shuttle accelerated into space to overcome Earth's gravity.
It takes about 8.5 minutes for a space shuttle to reach space after launch. The space shuttle accelerates to a speed of about 17,500 miles per hour to overcome Earth's gravity and enter space.
It has to overcome its' own weight and obtain a speed of 17,500 miles an hour to escape the Earths' gravitational pull. That is 3.38 x 1012 Joules. 3,380,000,000,000 joules.
17,500 miles per hour puts the shuttle in orbit. BUT the gravity is still there. I'm fact there is about 90% of the gravity while the shuttle is on the ground. That great rate of speed is required to keep the shuttle from falling back to earth. At that speed the shuttle is basically falling around the planet.
A space shuttle is able to float because there is no gravity in space.

Well they are used because without them the space shuttle would not be able to have enough force to escape the earths gravity when it was being launched.

You have to overcome the force of gravity. So, if you're in the space shuttle which weighs 240,000 pounds at liftoff, you have to have enough force to overcome that weight.

There is no gravity in space but the shuttle stays in orbit because of the Earths gravity and inertia. The inertia keeps it going in a circular motion. In space the Earth's gravity is strong enough to hold something in orbit but not strong enough to pull it to Earth's surface.
because to get to space you have to overcome the pull of earths gravity

Although it reaches incredible speeds, a Space Shuttle is not going fast when it enters the atmosphere. The gravitational pull of Earth, or just gravity, are pulling down on the space shuttle with immense force.
