A body can escape the gravitational pull of the earth if it is thrown up with a velocity of?
An object would need to start at about 25 miles per second in order to escape Earth's gravity.
What speed do rockets break earths gravitational pull?
Enough to support their own weight, plus a little more for motion. It is possible, in theory, to imagine a rocket moving away from the Earth at a slow walking pace. In real life you don't do that, you get away from Earth's pull as quickly as you can manage to do so.
Are black holes mass heavier than your sun?
Black holes suck in everything around it for billions of miles, all of that matter is compressed into something smaller than a tennis ball. If you could calculate its weight, it would way many times the weight of our sun!
What does a liter of water weigh in space?
Weight depends on gravity. People seem to think there is no gravity in space yet the earths gravitational pull is quite strong for quite long. Think of the moon, its pulled by earths gravity long after our atmosphere gives way to the vacuum of space. A liter of water would be the same weight in space and would only fade over long distances. As a side note space begins at like 60-70 miles above the earths surface. If you took a space ship up 120 miles (well into space) and parked it, you would promptly fall back to earth like any object dropped from a height. Lack of atmosphere implies nothing about gravity.
What is the escape velocity of planet Jupiter in miles per hour?
The escape velocity of planet Jupiter is: ~133,097.71 miles per hour.
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 fast does Saturn v go?
over 24,000 miles per hour, on the final burn, which is 7 miles per second, which speed is needed to escape earths gravitational pull.
A body can escape the gravitational pull of the earth if it is thrown up with a velocity of?
An object would need to start at about 25 miles per second in order to escape Earth's gravity.
Why must a spacecraft reach escape velocity to be able to go to space?
A rocket needs to travel at 7 miles-per-second or about 25,000-miles-per-hour to leave the pull of earth's gravitational force, and reach outer space. This speed is known as escape velocity.
What does the term 'escape velocity' mean?
Escape velocity is what a moving body has to achieve in order not to be pulled back down to the planet. For Earth it is about 7 miles per second.
How much force does a space shuttle need to get into space?
It has to overcome its' own weight and obtain a speed of 17,500 miles an hour to escape the Earths' gravitational pull. That is 3.38 x 1012 Joules. 3,380,000,000,000 joules.
Why cant a spacecraft go beyond earths gravity?
The Earth's gravity is indefinite. The earth will always present a force on a spacecraft, no matter the distance. However, the force could become very very small with increased distance.A space craft can go past the point where earth's gravity will not cause them to fall back to Earth. Some crafts stay in orbit, so they are still close enough to the earth to stay "locked" into its gravitational pull, but other crafts such as the Titan have gone very far beyond.Any object with mass has an escape velocity. The escape velocity is the velocity at which an object must travel in order to escape the gravitational pull of the massive object. The escape velocity of the Earth is 11.186 kilometers per second (a little over 25,000 miles per hour). If an object can travel at that speed away from the Earth, it will travel away from the Earth and it won't be pulled back in.
Why doesn't the suns gravitational force affected you more than earths gravitational force does?
Because the sun is 93 million miles away, whereas the earth is, well, right here!
Can you escape gravity by going above the earths atmosphere?
No. To even reduce it by 75% you must travel out to 4000 miles.
Would a spacecraft need as much fuel to escape from the moons gravity as it would to escape from the earths?
Escape velocity for the moon is a little over 5000 miles per hour. For the earth it is about 25,000 miles per hour. So the moon requires a fifth of the energy required to escape the earth.
How fast do you need to go to escape earth's gravity?
The speed or velocity an object needs to escape from the gravitational field of a planet is called "Escape Velocity" In other words, the amount of kinetic energy needed to overcome the gravitational field. The expression is given in 1/2mv^2 - GMm/r (m= mass of object trying to overcome gravitational field) M(mass of the planet) V(Escape Velocity) G(universal constant which = 6.67E-11) r(distance from surface of planet or w/e) when you derive that formula, you will find that the velocity needed is: V= *square root of: 2GM/r
What is meant by the 'escape velocity' of a rocket leaving the earth?
There is a speed, about seven miles a second, that if reached, will allow an object to overcome the earth's gravitational pull and continue into space. Rockets don't actually need to do this speed, since their objective is usually to establish an orbit around the earth.
