It can never escape it entirely. It can, however, travel fast enough that the increasing distance outweighs the effect of the decreasing gravity. On earth, this velocity is about seven miles per second.

How does a single stage rocket get off the earth?
I have heard of a single stage rocket ever being able to escape Earth's gravity.
Why must a spacecraft reach escape velocity to be able to go to space?
A rocket needs to travel at 7 miles-per-second or about 25,000-miles-per-hour to leave the pull of earth's gravitational force, and reach outer space. This speed is known as escape velocity.
Why can a rocket fly into space?
it can fly because the fire that comes out of the back of the rocket is its thrust.So when the fire comes out the back it causes the rocket to thrust forward.Remember the fire comes out with a lot of force thats why the rocket is able to fly because of the thrust. The body of the rocket is a device that can stay in space and float in there which allows the rocket to stay in space. The fire thrusts the rocket up but only to get out of earths atmosphere because earth has gravity space doesn't. In space the rocket does the rest of the work which is floating in a place without gravity. hope this helped!
Force required to break from Earths atmosphere?
To be able to escape earth's atmosphere you need to achieve a velocity that is great enough to achieve sufficient energy to escape the earth's gravitational field strength.
How is a real rocket able to blast into space?
the pressure from the the rocket's fuel thingy makes the rocket go up. pretty soon, the rocket is in space.

Why boosters are used in space shuttle?
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.

How are you able to stand on earth if it is a sphere?
GRAVITY! (pulling you towards the Earths centre)
Do you have to be skilled to go to the moon?
Yes you have to be able to handle the gravity and you have to know how to fly the rocket.
Would you be able to jump on the moon?
you would be able to jump on the moon. the moon's gravity is 1/6 of earths gravity so there is a bit of gravit but not alot so you will be able to jump abit
Why is it important not to have any leaks in a water bottle rocket?
If you have leaks in a water bottle rocket, the pressure will quickly escape along with the water and the rocket won't be able to reach as high an altitude as a rocket without leaks.
Can you hit a baseball to the moon?
No, you would not be able to hit it hard enough to escape the Earths gravitational pull.
What is the comparison between the earths gravitationnal force with mercury?
The gravity of Mercury is approximately 38% that of Earths gravity at the surface.Here are some comparisons:A 150 lbs person would weight 57 lbs on Mercury.You would be able to jump about 2.63 times as high on Mercury making a person capable of jumping over their head doing a standard stationary vertical jump.The moon's gravity is 16% of the Earths gravity as opposed to Mercury's 38%

To be able to escape earth's atmosphere you need to achieve a velocity that is great enough to achieve sufficient energy to escape the earth's gravitational field strength.
What speed do rockets travel at?
A rocket must travel at least seven miles per second in order for gravity to not be able to pull it back to Earth.
