The gravity of a black hole is stronger than Earth's gravity. Black holes have such a strong gravitational pull that not even light can escape from them.
There is indeed a relationship between gravity and atmospheric pressure. Gravity attracts matter with mass, in this case gas. The atmosphere being a layer of gas, the stronger the gravity, the higher it's pressure. I if you seal gas in a tank, and increase its mass (by adding more gas) the pressure will increase. Now imagine that the tank is the earth, and gravity is exerting a down force on the gas... It's like water. Although it can't be compressed, water exerts pressure because of gravity; the deeper you go the higher the pressure. Now imagine the atmosphere pressure on Jupiter....
Earth's lighter gases such as Hydrogen and Helium will rise to the top of the atmosphere. Since they are very light, they will easily be knocked awry by the solar wind, the stream of charged particles coming from the Sun.
The general idea is that the escape velocity from Earth is 11.2 km/second. This assumes there is no atmosphere. I guess "thrust" would be expressed in units of force; the force can be just about anything, from just slightly bit more than the object's weight (to counter Earth's gravity), to a lot more, depending how long the force is applied. In other words, if you apply more force, you need to apply the force for less time to achieve escape velocity.
No, Its gravity is much lower due to a lower overall mass of the planet. Mars' gravity is about 37.6% of the Earths.
escape velocity if its leaving earths gravity
No. It cannot escape the Earths gravity.
For the same reason that our atmosphere on Earth does not escape into space - gravity.
Mercury has very weak gravity.

Gravity.
No. To even reduce it by 75% you must travel out to 4000 miles.
it's small size and low gravity
Today's rockets use chemical fuel for this. That is, they burn something.
The gas giant planets have stronger gravity, which makes it harder for anything to escape, and are colder, which means that even with similar gravitational fields, gas molecules might not achieve escape velocity.
because the gravity keeps the giants planets' gases from escaping.
