The force of gravity is proportional to the masses of the two objects and inversely proportional to the square of the distance between them. As a result, a gravity of one fourth that on the surface of the Earth would be observable at an altitude equal to the radius of the Earth, i.e. 6400 km. Note: This is up, in the air, not down, into the Earth. This distance is in outer space.
In the other direction, the force of gravity gets smaller as one goes deeper into the earth. This is because the mass outside your current radius (as you descend) does not contribute. The mass inside your current radius is proportional to the cube of the radius. Gravity is proportional to this mass divided by the square of the radius. Therefore, gravity decreases linearly with the radius. So the acceleration of gravity is equal to one fourth its value at the earth's surface at one fourth of the earth's radius, or a depth of approximately 4800 km.

What are the factors on which pressure exerted by liquids depends?
The factors on which pressure exerted by liquids depends are: 1. The density of the liquid 2. Acceleration due to gravity and 3. Depth of the point below the surface of the liquid.
What is acceleration due to gravity on Jupiter?
We can calculate the gravity on any planet or star by using this formula g = GM/r2 where M is mass of the planet or star G is universal gravitational constant g is acceleration due to gravity & r is the radius of the planet or star. Mass of Jupiter is 1.9 X 1027 kg Radius of Jupiter is 7 x 107 m Putting the values in formula we get g = (6.673 x 10-11) x (1.9 x 1027)/(7 x 107)2 = 26m/s2
Is acceleration due to gravity constant?
Yes, but you don't experience it around here.The part of acceleration that's due to gravity is constant, but anything that fallsthrough air experiences an increasing air-resistance force as it falls faster, andit eventually stops accelerating, at a speed called its "terminal velocity".If you rig up a situation where there's no air, and you can witness the pure effectsof gravity, then things really get interesting ... like a bowling ball and a feather bothfalling together and hitting the bottom at the same time. Many museums have exhibitslike that set up, with a large transparent shaft from which the air us evacuated, andin which they drop things.No. acceleration due to gravity depends upon i) height above the earth's surface ii) depth below the earth's surface iii) rotation of the earth iv) shape of the earth. it decreases with the height above the earth's surface:it decreases with the depth below the earth surface, it decreases with the speed of the rotation. it is zero at the centre of the earth.
Why does liquid exert equal pressure at the same depth?
Pressure = h d g h is the depth, d the density of the liquid and g- acceleration due to gravity. As d and g remain constant, same h would have the same pressure. Hence the case.
How does the pressure at a certain depth in sea water differ from that at the same depth in river water?
Since liquid pressure is function of density,acceleration due to gravity and depth of liquid level so here density of sea water is greater than that of river water ,so liquid pressure in sea must be more.
What is the relationship between liquid depth and pressure?
the pressure of liquid is HDG where H=depth D=density g= acceleration due to gravity thus depth= pressure/density*acceleration due to gravity
What are the factors on which pressure exerted by liquids depends?
The factors on which pressure exerted by liquids depends are: 1. The density of the liquid 2. Acceleration due to gravity and 3. Depth of the point below the surface of the liquid.
What is the effect of depth on the earth on the value of g?
As soon as you go below the surface, it will decrease (dont ask for the calculations) until at its centre where acceleration due to gravity will be 0.
What is the relationship between liquid and pressure and depth of a liquid?
The Pressure and depth of a liquid are related by the equation P= dgh., where d is the density, g is the acceleration due to gravity and h is the depth. This value gives us the gauge pressure that is the excess above the atmospheric pressure.This is explainable with Archimedes principal giving the pressure at the base of the column with the formula Sg x H x G
What are facts about Neptune's gravity?
There's really only one fact about Neptune's gravity that's any different from the gravity of any other planet, asteroid, comet, or star. The acceleration of gravity at the surface of Neptune is 11.257 meters/second2 . That's 14.8% greater than it is on the surface of Earth, and 6.94 times the value on the surface of the moon. Note: When dealing with gaseous bodies, the 'surface' is considered to be the depth at which the gas pressure is equal to Earth's sea-level atmospheric pressure.
How much more gravity is there on Neptune than there is on Earth?
The 'surface' acceleration of gravity on Neptune is 11.15 m/s2 . That's about 14% greater than on the Earth's surface. If you weigh 200 pounds on Earth, then at the depth in Neptune's gaseous mantle where the pressure is equal to Earth's sea-level atmospheric pressure, you'd weigh about 228 pounds.
What is acceleration due to gravity on Jupiter?

How do you convert from Mercury to pascals?
Multiply the depth of Mercury by the density of Mercury (kg per cubic metre) and the acceleration due to gravity(m/s²)

What is the force of gravity on the surface of Saturn?
The acceleration of gravity at the surface of Saturn is 11.171 meters per second2. That's about 1.139 times its value at the earth's surface. Whatever the object's weight is on earth, it's about 11.4% more on Saturn.
What is the depth of earth surface in kilometers?
A surface has area but no depth. Therefore the Earth's Surface has a depth of 0.0 kilometers.
What is the formula is used to calculate the pressure in a liquid?
The formula relating the pressure in a liquid to the depth of the liquid is P = P0 + dgh. P is the pressure, P0 is atmospheric pressure, d is the density of the fluid, g is the acceleration of gravity, and h is height below the surface of the water.
