Why is the acceleration due to gravity on the surface of Mars is about one third the acceleration due to gravity on earths surface?
Because the acceleration of gravity on the surface of any given body depends on the mass of the body and its radius ... the distance of the surface from the center. Mars' mass ... about 11% of Earth's ... and Mars' radius ... about 53% of Earth's ... combine to produce about 38% of Earth's gravitational acceleration at the surface of Mars.
What is the acceleration due to gravity 9000000 meters away from the center of the earth?
If you have a known rate of acceleration and radius (such as at the earths surface), you can use the following equation to calculate the acceleration at another radius.a = k / ((d / r)^2)key:a = new acceleration rate ((m/s)/s)d = new radius (metres)k = known acceleration rate ((m/s)/s)r = known radius (metres)so if:d = 9 000 000 metresk = 9.82 (m/s)/s (acceleration at earths surface)r = 6 371 000 metres (radius at earths surface)then:a = 4.92 (m/s)/s
What depth from surface of earth is value of acceleration due to gravity one fourth the value at the earth surface?
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.
How much would the force of gravity at the surface of the Earth differ if Earth volume were increased 125 times and its mass 25 times?
Assume an initial gravity of 1 unit. Calculate the change in radius from the change in volume. That would be the third root of the volume. Divide by the radius squared.Also, multiply by the increase in mass, i.e., by a factor of 25. Since you started off by 1 unit of gravity, the final result will tell you by what factor the force of gravity increased.
The weight of the body on the surface of the is 250N. calculate its weight at distance equal to half of radius of the earth below the surface of earth. (radius of earth6400km)?
This is hard to calculate precisely, due to the fact that Earth's density increases towards the center. However, you make a simplified calculation, by assuming a uniform density. Just calculate the ratio of the volume (and therefore, of mass) of a sphere which has half the radius of the Earth, and calculate the gravitational attraction (once again, you only need a ratio, compared to the complete Earth) on that object.

Is the earths radius and surface area increasing?
no

Calculate to 1DP the radius of a sphere when the surface area is 150?
The radius is 3.45
Why is acceleration due to gravity the same for all objets?
because all are measured at the same radius from the earths cog, if you doubled this distance, the acceleration would be only one quarter that of the surface
How big is the earths kilometer above its surface?
The radius of Earth in kilometers is 6400 km.The earth is big in 6400 km in radius above its surface.
Why do we know the gravity on the moon compared on earth?
We can know through two ways. First, we know the moon's mass and radius. From there it is fairly simple to calculate surface gravity. Second, we have sent probes and people to the moon, making it possible to actually measure the strength of gravity.
How do you calculate the surface area of a hemisphere?
2(pi)radius^2

How many times is the suns radius bigger than earths surface?
109 Actually, no. 109 would probably be for Jupiter. For Earth, hundreds of Earth's surface could fit in the sun's radius.
How does the gravity of mars vary with its mass?
-- If the mass of Mars increases, then its surface gravity also increases. -- If the mass of Mars decreases, then its surface gravity also decreases. -- So long as its radius does not change, the acceleration due to gravity on or near the planet's surface is directly proportional to its mass.
Is the pull of gravity from other planets the same as Earth?
No. The gravitational pull at the surface of a planet depends on that planet's mass and radius. Jupiter has the strongest gravity of any planet in the solar system: 2.53 times the surface gravity on Earth. Mercury has the weakest surface gravity at just 37% the gravity on Earth.
