Gravity does not stop outside the Earth's atmosphere. Gravity's range is theoretically infinite, so you will never be free of its influence. Every object has gravitational attraction for every other object in the universe. The force of that attraction is greater for objects with greater amass, and is gets less as the distance between the two increases.
The only way to not notice gravity's influence is to be in free fall. They you don't have anything opposing your movement toward the large attracting object (the earth) and you don't feel the attraction (the weight). As such weightlessness is experienced by astronauts in a spacecraft in orbit, so it is in free fall.
What else can I help you with?
Is gravity a variable?
Gravity is a constant force that acts upon objects with mass, causing them to be attracted to each other. While the strength of gravity can vary based on the mass of the objects and their distance apart, it is not considered a variable in itself.
Why does the atmosphere not just float away. Surely gravity isn't strong enough since it doesn't even stop steam rising?
The atmosphere is held in place by Earth's gravity, which is strong enough to keep it from floating away into space. The molecules in steam are moving faster than air molecules in the atmosphere, so they can rise against gravity. The atmosphere is trapped by Earth's gravitational pull, preventing it from escaping like steam.
What 2 forces are acting on a falling object in the earths atmosphere?
The two main forces acting on a falling object in Earth's atmosphere are gravity, which pulls the object downward, and air resistance (also known as drag), which opposes the object's motion and slows it down as it falls.
How does gravity affect an object in motion?
it pulls the object towards the earth which kind of slows it down i guess. or is that friction? For an object travelling in the Earths atmosphere, or near to the Earth above the atmosphere, gravity provides a force pulling the object towards the centre of the Earth. Unless the object is travelling fast enough, what is called the escape velocity, this gravity force will ultimately cause the object to fall back to the surface. Friction is something else, the friction with the air in the atmosphere also slows the object, but this force acts in opposition to the direction of motion, not towards the Earths centre. To compute the trajectory of the object you need to take both forces into account.
Which layer do light gases escape earths gravity?
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 earths atmosphere came from where?
Gravity pulled it in.
What is the the earths moons atmosphere?
There is no atmosphere on the moon. There is insufficient gravity to keep an atmosphere there.
What is the difference between the earths atmosphere and the earths gravity?
The two are completely unrelated.
What force holds the particles of air in earths atmosphere?
The Earth's gravity.
When earths early atmosphere formed which gases where lost because earths gravity was too weak?
Hydrogen and helium
What force holds the atmosphere to earths surface as it travels through space?
Gravity.
Why air pressure from earths atmosphere is not the cause of gravity?
Gravity is an entirely separate entity which is a consequence only of the mass of the earth itself. In fact, the atmosphere presses down because gravity is pulling on it.
What causes meteors to enter earths atmosphere?
Gravity. And the meteor is on a path that intersects the orbit of the Earth.
What holds the atmosphere to the earth?
The earths gravity. The more mass a body has, the more gravity, The Earth has enough mass to hold an atmosphere. The Moon, on the other hand, is not massive enough, and so does not have a high enough gravity, which prevents it from holding an atmosphere.
What two things does momentum count on to keep in act?
Outside earths atmosphere its Gravity, and on Earth its Mass and Velocity.
Can you escape gravity by going above the earths atmosphere?
No. To even reduce it by 75% you must travel out to 4000 miles.
Could Jupiter's atmosphere stop the earth?
yes it could cause of its gravity
