What is the magnitude of the gravitational force between the earth and a 1-kg body?

The earth's gravity varies a bit from the equator to the poles and also from sea level to altitude. Fortunately we have a definition for "standard gravity" on earth, and it's 9.80665 m/s² (32.1740 ft/s²). We'll need that, and we'll need to figure out and define force so we can measure it. Force due to gravity is the "pull" of gravity, and it is the attraction of the mass of the earth for this other mass that weighs 1 kilogram. There is a simple equation used to measure force: Force (F) = mass (m) times acceleration (a) For force supplied by gravity, we use the gravitational constant (g) for the acceleration. F = m times g We know the gravitational constant, so we'll just plug it in. And we'll simply plug in the mass you asked about, which is 1 kilogram, to come up with this: F = 1 kg times 9.8 m/s2 That means you've got 9.8 kilogram meters per second2 for your force. Force is measured in Newtons, and a Newton is 1 kilogram meter per second 2 so if you have 9.8 kg meters / second2 then you have 9.8 Newtons acting on your 1 kg mass.

∙ 11y agoA one kilogram body on the surface of the Earth is attracted to the Earth by a force that is simply its own weight.
The weight of an object is defined to be the force of attraction to Earth on the surface of the Earth unless someone gives you a different location. One can ask, for instance, what is the weight of a one kilogram mass on the moon?
It doesn't matter, on the surface of the Earth whether you caculate teh force with the law of gravitation,
F=(G(m1 times m2))/d^2
or you just use
F=mg.
In the case of 1 kilogram, you get 9.8 Newtons or 2.2 pounds depending on your choice of units.

∙ 14y agoThe gravitational force on an object located at the earth's surface and whose mass is 1 kilogram is approximately 9.78 Newtons, or 2.205 pounds.

∙ 9y agoOn or near the surface of the Earth, it's 980 newtons.
Wiki User
∙ 14y agoThe earth and the rock are attracting each other with equal forces.
Each force is about 9.8 newtons, or about 2.2 pounds.
Wiki User
∙ 14y ago9.8 newtons (2.204 pounds) (both rounded), as long as the body is
reasonable near the earth's surface.
Wiki User
∙ 14y agoSince the force of gravity is F = mg
F = Force (in N)
m = mass (in kg)
g = acceleration due to gravity = 9.8 m/s2
F = 1 x 9.8 = 9.8 N

What happend to the gravitational force between two objects if the distance between them is decreased?
The gravitational force that one object exerts on another will decrease in magnitude. In the formula for gravitational force, the force is inversely proportional to the square of distance. This means that reducing the distance between the objects will increase the magnitude of gravitational force.
Strength of force between the moon and earth if the mass of the moon doubled?
If one of the two masses doubles but the distance between them remains unchanged,then the magnitude of the gravitational force between them is also doubled.
Is mass the magnitude of the force due to gravity on an object?
No mass is not the magnitude of the force due to gravity on an object. Mass is the stuff of which the object is composed. The magnitude of the gravitational forces between the object and Earth ... or whatever planet the object happens to be on ... is the object's "weight".
What is the magnitude and direction of the gravitational force that acts on a woman who weighs 500 N at the surface of earth?
The magnitude of the force is 500 N. The direction is toward the center of the earth, i.e. downward.
What must you know to find the magnitude of the gravitational force of attraction between the earth and the sun?
Gravitational force= G*m1*m2/r^2 G - universal gravitational constante m1 - mass of object 1 m2 - mass of object 2 r - distance between the objects
What would happened to the magnitude of the gravitational force between the sun and Earth if earth were placed in Pluto's orbit?
The magnitude of the force would decrease greatly.
What would happen to the magnitude of the gravitational force between the suns and earth if earth were placed in Pluto's orbit?
The magnitude of the force would decrease greatly.
What would happen to the magnitude of the gravitational force between the sun and Earth if Earth were placed in Pluto's orbit?
The magnitude of the force would decrease greatly.
How is mars gravitational force different from earth?
Only in its magnitude ... about 38% of its magnitude on Earth.
What is the magnitude of the gravitational force between the you and earth?
Multiply your mass (in kilograms) by 9.8. That will give you your weight in newton. The weight is, precisely, the gravitational force.
When you step on a weigh scale what are you really measuring?
You are measuring the magnitude of the gravitational force that attracts your mass towards the center of the Earth, and the magnitude of the gravitational force that attracts the Earth towards you.
How does mass affect the magnitude of gravitational force?
The magnitude of gravitational force between two objects is directly proportional to the product of their masses. This means that as the mass of one or both objects increases, the magnitude of the gravitational force between them also increases. In simpler terms, the more massive an object is, the stronger its gravitational pull.
What what happened to the magnitude of gravitational force between the Sun and Earth if earth was place in Pluto's orbit?
it would be less than what it was before

Is there magnitude of the gravitational force on Mars?
Yes, it is about one third of that of the earth

it would be less than what it was before
Does the gravitational force vary with the distance between earth and sun?
The gravitational force between the Earth and sun certainly depends on the distance between the Earth and sun. But the gravitational force between, for example, the Earth and me does not.
