Why did free hydrogen in terrestrial planets atmosphere escape?
cause it felt like it
Why will astronauts probably never set foot on any of the giant planets?
I am not sure how probable this is; but here are some of the practical difficulties.The gian planets don't really have any surface where anybody can "set foot on". They are just gas giants; the gas goes way down. An astronaut might be able to set foot on a platform floating in the planet's atmosphere, but not on the planet's surface, since these gas giants have no surface.The gravity of these planets is very strong. On Jupiter, an astronaut would have trouble standing up, since his weight would be more than twice what he weighs on Earth. On Saturn, an astronaut would weigh even less than on Earth - but it would require a tremendous amount of energy to get such an astronaut back out from Saturn. Or any of the giant planets. Look up the "escape velocities" - squaring these velocities gives you an idea of the amount of energy required. For example, on Earth the escape velocity is 11.2 km/second - and escaping from Earth is already a considerable engineering challenge. Saturn's escape velocity is 35.5 km/second - meaning that in theory, it would take about ten times as much energy to escape from Saturn, than it takes to escape from Earth.
How do you increase a planets escape velocity?
Smoke some weed
Does the escape velocity on a planet depend upon its density or mass?
No, its depends on the planets gravitational pull
How does the escape velocity from a black hole compare with the speed of light?
The escape velocity of a black hole is equal or greater than the speed of light, so light cannot escape

Why is it more difficult for gases to escape from Jovian planets than terrestrial planets?
Jovian planets have a much stronger gravitational force due to their larger mass.
Which process explains why the terrestrial planets do not have hydrogen and helium in their atmospheres?
The terrestrial planets are less massive and therefore have less gravity. As a result, much of the lighter gases could escape, in the process of planet formation.
Why don't other planets have atmosphere?
because their escape velocities are not sufficient to hold back the molecules of other constituents(ex. nitrogen oxygen etc.)
Does air molecules escape into space?
Air molecules do escape into space it depends on how heavy or hoe light they are. However, lighter molecules of air have greater velocities while heavy molecules of air has less velocities were gravity pulls the air downwards.
To escape from a planets gravity an object must reach a speed called the?
Escape Velocity

The atmosphere of the gas giant planets cannot escape into space because?
the planets have very strong gravitational pulls.
How much speed required to go against gravity?
Assuming there is no air resistance, if an object starts at a speed of 11.2 km/sec, it can escape the gravitational field of Earth. This "escape velocity" is different for different planets, moons, etc.Assuming there is no air resistance, if an object starts at a speed of 11.2 km/sec, it can escape the gravitational field of Earth.

Is escape velocity same for all objects?
Yes. It is different for different planets etc. Escape velocity on earth is different than escape velocity on Jupiter.
What is the path of an object as it revolves around another object?
Depending on their relative masses and velocities, the path of the smaller will be a circle, or more likely, an ellipse. An old model for this is to consider a canon mounted at the top of the globe. Firing a shell at moderate velocities, it will fall to Earth quite soon. At a much higher velocity it will have sufficient energy to make a circle round the globe. At higher velocities again, it will form an ellipse. Eventually we reach escape velocity, where the shell just continues on a giant ellipse - really, an escape.
