Lift-off
It saves on fuel. The reason we launch rockets from Florida as opposed to say, Long Island, New York, is that we are closer to the equator, the mid-point between the north and south poles. If you were to spin a basketball, you would see that the center rotates faster than the top or bottom of the ball. This means that when the rocket blasts off from the launch pad, it gets an extra boost from the rotation of the earth and that means less fuel needs to be used to lift off. Another reason is that the launch is done over water. If sonething were to happen to a rocket after lift-off, the rocket would come down over water and not land (remember the Space Shuttle).
Launch Pad
it dosent, its very hard to get a space shuttle off the ground it uses thaousands of pounds of force to lift it.
Your question is very broad. One of the things a rocket takes off from is called a launch pad. Launch pads are the place where rockets take off. But the things that cause it to take off are completely different. A rocket takes off or 'launches' from a concept called thrust. Thrust is when say I have a ten pound ball that I want to throw directly up in the air. I need to create 10 pounds of energy to launch it and then enough energy to actually get it to where I want to go. Those are the basic things that make a rocket launch.
Lift-off
It means when a rocket leaves its launch pad. "Lift Off!"
If the gantry explosive bolts didn't get you, you would be fried within a second of lift off as the main engines burnt your skin off.
Yes, water is flooded extremely fast into the launch pad 3 seconds before lift-off. This is actually for sound reasons, so the extremely loud sound produced from the shuttle is muffled. Without this liquid, the sound would bounce of the launch pad and the vibrations would shake the shuttle dangerously! Check out www.nasa.gov for more infomation.

There were two onboard the Challenger space shuttle which was destroyed during launch in January 1986 when the external tank exploded 73 seconds after lift-off. They were mission specialist Judith A. Resnik (on her second shuttle flight) and Christa McAuliffe, who was to have been the first teacher in space.
From the time the Space Shuttle's on-board computers start the launch sequence until the time the shuttle actually lifts off the pad is about 31 seconds. About 60 seconds after lift off, the engines on the shuttle are at maximum throttle.
Because it's too heavy ! It would take much bigger and more powerful rockets to lift a craft made of iron off the launch-pad.
Petrol does not have a high enough energy density. If you have enough of it on board to provide the energy needed to reach orbit, the vehicle will be too heavy to lift off.
ZERO... we have Lift-off!
It isn't you need to launch it off my dick
