What is the measure of the earth's gravity on an object?

Answer 1

Mass and distance is the measure of the strength of earth's gravitational pulll

The Law of Universal GravitationSince the gravitational force is experienced by all matter in the universe, from the largest galaxies down to the smallest particles, it is often called universal gravitation. (Based upon observations of distant supernovas around the turn of the 21st cent., a repulsive force, termed dark energy dark energy, repulsive force that opposes the self-attraction of matter (see gravitation ) and causes the expansion of the universe to accelerate. The search for dark energy was triggered by the discovery (1998) in images from the Hubble Space Telescope of a distant

The constant of proportionality in this law is known as the gravitational constant; it is usually represented by the symbol G and has the value 6.670 × 10−11 N-m2/kg2 in the meter-kilogram-second (mks) system of units. Very accurate early measurements of the value of G were made by Henry Cavendish.

IDK!!!!!!!!!!!!!!!!!!!!!!!!!! NO one knows. I've searched everywhere

Answer 2

Newton is how we measure the gravitational pull on matter which has mass. On earth an object that has the mass of one kilo had the force of 10 Newtons upon it, ergo on earth 1 kilo is 10 Newtons. On the moon where there is but one sixth the gravity of the earth that object that has a mass of one kilo will only have 1.5 Newtons.

Answer 3

The magnitude of the mutual gravitational force of attraction between the earth

and any object on earth is what we call the "weight" of the object. It's important

to understand that the earth is attracted toward the object with the same amount

of force.

Answer 4

F=GMm/r2

F=force of gravity (in Newton (N) )

G= the universal gravitational constant (6.67428(10-11m3Kg-1s-2))

M=Mass of first object in Kilograms

m=Mass of the second object in Kilograms

r=The distance between the center of the two masses

It's all fairly straight forward. The hardest part is remembering G

Answer 5

A single object doesn't have a gravitational attraction. The gravitational force between two objects

is proportional to the product of both of their masses. So the force between the earth and any other

object ... like a person ... depends on the mass of the person, just as much as it depends on the earth's

mass.

You can't tell the strength of the earth's attraction of an object until you know the object's mass.

(In other words, you don't know how much a person on earth will weigh until you know something

about the person.)

Answer 6

One easy way to do it ... with equipment you may already have around the house ...

is to put it on a bathroom scale. The scale will display the magnitude of the mutual

gravitational force of attraction between the earth and the object.

Answer 7

You weigh yourself.

How much you "weigh" is the amount of gravitational pull the Earth has on you.

It's also the amount of gravitational pull you have on the Earth. You can prove

that by turning the scale upside down, and weighing the Earth on you.

Answer 8

-- Borrow a bathroom scale. Put it on the floor.

-- Put the object on the bathroom scale.

-- The scale directly displays the magnitude of the mutual gravitational forces

between the Earth and the object.

That's the force that pulls the object toward the Earth.

It's also the force that pulls the Earth toward the object.

Answer 9

F = m * a

F.... Force (newton [N])

m... Mass (kilogram [kg]) (yes, it's actually not gram)

a.... Acceleration (meters per square seconds [m/s²])

And since the acceleration of the gravitation is 9.81 m/s² and called g the exact formula is:

F(g) = m * 9.81
