Is the escape velocity of hydrogen at mars more than it's gravity or in other words can hydrogen in gaseous state exist on the planet mars?
Hydrogen probably cannot exist for a long time on Mars. As you suggest this is
because of the planet's fairly low gravity and escape velocity. It's easier for a
very light atom or molecule, such as hydrogen, to reach the planet's escape velocity, caused by collisions in the atmosphere.

What is escape volocity?
Escape velocity is the minimum speed that an object must reach to break free from the gravitational pull of a celestial body. This velocity allows the object to overcome the body's gravitational force and enter into space. The specific value of escape velocity depends on the mass and radius of the celestial body.
Why you must study escape velocity?
You don't. "Escape velocity" is a meaningless number. "Escape velocity" is the speed at which a CANNON SHELL must be fired in order to escape from the Earth's gravity well. With a powered rocket, you can "escape" from the Earth's gravity at ANY speed - as long as you have enough fuel.
A body can escape the gravitational pull of the earth if it is thrown up with a velocity of?
In order for a body to escape the gravitational pull of the Earth, it needs to be thrown up with an initial velocity equal to or greater than the escape velocity of around 11.2 km/s. This velocity allows the object to overcome the gravitational pull of the Earth and continue traveling away from it indefinitely.
Does escape velocity depend upon height from which it is projected?
Yes, it would. That's one reason why some artificial satellites were tossed into orbit after being carried up aboard the space shuttle. The reason is because escape velocity from Earth depends on Earth's gravity, which in turn depends on the distance from the Earth's center. The higher you go, the farther you are from the center of the planet, the less gravitational force there is between you and the Earth, and the smaller the escape velocity thus becomes.
How is escape velocity obtained?
"Escape velocity" is a misnomer; there isn't any such thing. "Escape velocity" is the speed that it would take a projectile to escape completely from the Earth's gravity, IF IT WERE FIRED FROM THE SURFACE FROM A CANNON.The "escape velocity" from Earth is about 7 miles per second, or 25,000 miles per hour. But the Apollo spacecraft that went to the Moon didn't go anywhere near that speed. It didn't have to, because it was propelled by a rocket engine. With a big enough engine and enough fuel, you could "escape" from the Earth at 5 miles per hour, or less. It would be TERRIBLY wasteful of fuel, which is why we don't do it that way.
What is velocity that a rocket must attain to escape the force of gravity on earth?
The velocity of a any object to surpass the gravity of earth commonly known as escape velocity is 11.2Km/s.
How do you beat gravity on Earth?
To overcome gravity, you must reach "Escape Velocity" to overcome gravity and escape a planet's orbit.
What is te Formula of escape velocity?
Escape velocity is given by. √2gR or √2GM/R .therefore escape velocity is directly prop. to gravity of a planet or star or any other body. More is the gravity more is the escape velocity. The escape velocity of our earth is 11.2 km/s and that of moon is 2.31 km/s
To escape from a planets gravity an object must reach a speed called the?
Escape Velocity
Why would escape velocity be different on a different planet?
The escape velocity is determined by the gravity of the planet which in turn is determined by the mass and size of the planet
How does the atmosphere keep oxygen inside?
Inside what? Oxygen is part of the atmosphere. The thermal velocity of its molecules are insufficient to escape earth's gravity (unlike hydrogen molecules which are fast enough).
What is the name for the speed a rocket must reach to escape the earth's gravity?
Escape velocity is the speed that a rocket must reach to break free from Earth's gravity and enter space. It is the minimum velocity required for an object to overcome the pull of Earth's gravity.
What is the trajectory of a projectile having velocity greater than escape velocity?
It will eventually straighten out as it escapes gravity.
What may happen to a rocket which rises from the earth never attains escape velocity?
A rocket that doesn't reach "escape velocity" will be overcome by gravity and will be pulled back down to Earth. Also, rockets which go into orbit have not reached escape velocity. Escape velocity is what is needed to completely leave earth's gravity well.
What is Rocket speed per sec to escape from earth gravity?
the rocket speed required to escape out of the earth's gravity is known as escape velocity which is numerically equal to 11.2 km per sec.
What is the action of the spacecraft leaving the earth called?
escape velocity if its leaving earths gravity
What is escape volocity?
Escape velocity is the minimum speed that an object must reach to break free from the gravitational pull of a celestial body. This velocity allows the object to overcome the body's gravitational force and enter into space. The specific value of escape velocity depends on the mass and radius of the celestial body.
