The escape velocity depends only on the mass and size of the object from which something is trying to escape. The escape velocity from the Earth is the same for a pebble as it would be for the Space Shuttle.
Q. Do satellites reach escape velocity?
Most satellites and spacecraft sent into space do not reach escape velocity! If a rocket goes fast enough and high enough to enter space but does not reach escape velocity, it will enter orbit around the Earth.

Q. Does escape velocity depend on height?
The escape velocity is independent of mass of the body and the direction of projection. Since this potential depends on the height of the point of projection, the escape velocity depends on it.
Q. Is escape velocity directly proportional to mass?
The escape velocity of a body is directly proportional to the square root of mass (M) of the planet (earth) around which the satellite is orbiting. The escape velocity of a body is inversely proportional to the square root of the radius of the Planet.
Q. Does density affect escape velocity?
The escape velocity of an object from the earth depends upon the mass of the earth ( M ), its mean density (ρ), its radius ( R ) and the gravitational constant ( G ).
Q. What is escape velocity proportional to?
The escape velocity is proportional to the square root of M/R, so the ratio is equal to the square root of 16/2 = 2.828.
Q. Why do we need escape velocity?
Escape velocity is the speed required to escape gravity in the absence of any force being applied. So yes, of course it is possible to keep going upwards and further from the earth, but without reaching escape velocity you would eventually be pulled back to earth when the fuel runs out.
Q. What is called escape velocity?
In physics (specifically, celestial mechanics), escape velocity is the minimum speed needed for a free, non-propelled object to escape from the gravitational influence of a massive body, that is, to eventually reach an infinite distance from it.
