What is the speed necessary to escape the earths gravity?
The speed at which a rocket must travel to escape the gravitational pull of the earth is 25,000 miles per hour.
How much thrust is needed to escape earths gravity if something weighs 1520?
Any force larger than the weight is sufficient, if it is applied long enough.
What is mars gravity force earths gravity equals 1?
No, Its gravity is much lower due to a lower overall mass of the planet. Mars' gravity is about 37.6% of the Earths.
Where does gravity pull people and objects?
On the earths surface gravity pulls you down.
How many joules are there in gravity?
joules have nothing to do with gravity. gravity is measured in g's earths gravity is equal to one G
What is the action of the spacecraft leaving the earth called?
escape velocity if its leaving earths gravity
Why doesnt the gas on a gas giant planet escape into space?
For the same reason that our atmosphere on Earth does not escape into space - gravity.
Can a Boeing 747 fly into a black hole at the edge of your universe?
No. It cannot escape the Earths gravity.
Why did the gas on mercury escape?
Mercury has very weak gravity.
Why can't the atmospheres of the gas giants just escape into space?
Gravity.
What is the speed necessary to escape the earths gravity?
The speed at which a rocket must travel to escape the gravitational pull of the earth is 25,000 miles per hour.
Can you escape gravity by going above the earths atmosphere?
No. To even reduce it by 75% you must travel out to 4000 miles.
Why doesnt the gas on a gas gaiant escape into space as it has on mercury?
it's small size and low gravity
Why doesen't the gas on a gas giant escape into space as it has on mercury?
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.
How does a rocket make enough thrust to escape earths gravity?
Today's rockets use chemical fuel for this. That is, they burn something.
Which planets surface gravity is 38 percent that of earths?
Both mercury and mars have a gravity which is around 38% of earths. Mercury's gravity is 37.8% of earths, Mars' gravity is 37.7% of earths.
Why doesnt the gas on a gas giant escape into space as it have on mercury?
because the gravity keeps the giants planets' gases from escaping.
