What else can I help you with?
How would the value of g and G be affected if mass of the earth becomes four times?
G would remain the same, it's the gravitational constant which is the same everywhere in the universe. g would increase by 4 times, assuming that the radius of the earth didn't increase.
All objects change velocity as they move toward earth at a rate of 9.8 ms2 due to which factor of gravity?
The factor of gravity responsible for causing objects to change velocity at a rate of 9.8 ms^2 as they move towards Earth is the acceleration due to gravity. This acceleration is constant near the surface of the Earth and is denoted by 'g'.
Is G is the force of gravity?
Nope. G is a universal constant that applies to all physical objects on earth. The product of an object's mass (m) and G will result in the object's weight, which is just the gravitational pull on the object (the force of gravity). G has the same unit as acceleration. See Newton's second law of motion.
Why value of g is bot constant on earth?
The value of g (acceleration due to gravity) is not constant at all points on Earth's surface because it is influenced by factors such as the planet's rotation, elevation, and density of the underlying materials. These variations cause slight fluctuations in g, leading to different values in different locations.
What is the constant for gravity?
The constant acceleration due to gravity on EARTH is -9.81 m/s^2. This constant does not apply to objects on other planets because the mass of another planet might not be the same as Earth's mass. Because acceleration due to gravity is constant, this will be the acceleration due to gravity no matter the position of the object on Earth.
Is the value of g equals 9.8m s constant?
No. It is an approximation for objects near earth, objects further away from earth experience less force and therefore dont have as great an acceleration.
When was g the earth's gravitational constant calculated?
g, the force of the Earth's gravitational attraction, is not a constant.

How do you know the suns mass?
By its gravitational effects. The law of gravitation states that F = G (m1) (m2) / r2; the constant "G" can be measured in Earth laboratories with a delicate instrument that measures the force between two objects; from there, the mass of Earth can be calculated, and from the mass of Earth, other objects in the Solar System (once the distances are also known).
What is the formula that tells the gravitational attraction between a mass and the earth?
F=G*(mass*mass of earth)/(distance between the objects)^2 Where G is the gravitational constant 6.67x10^-11 N m^2 / kg^2 and the mass of earth is 6.98x10^24 kg
Value of gravitational constant on earth and moon?
It's the same as that of Earth but the value of g varies from one object to the other. The value of the gravitational constant or the BIG "G" remains constant. I think you confused it with the LITTLE "g" which is the gravitation of a object (one with mass) or the acceleration due to gravity. The value of g on Earth and Moon is 9.8m/s^2 and 1.6249m/s^2, respectively. I hope this answers you all.

What factors affect the strenghth of gravity?
As Newton's law of gravity we know that g=GM/R^2 where G=gravitational constant=6.673*10^-11,M=earth's mass and R=distance of the object from the center of the earth. As earth's mass is constant and G is also constant so g or gravity only depends on the distance of the object.

The constant acceleration due to gravity on EARTH is -9.81 m/s^2. This constant does not apply to objects on other planets because the mass of another planet might not be the same as Earth's mass. Because acceleration due to gravity is constant, this will be the acceleration due to gravity no matter the position of the object on Earth.
Why does a heavier object fall with the same acceleration as the lighter object?
Because the acceleration due to earth (gravitation) dose not depends on the mass of falling object & it's constant for deferent masses :F= (G M m) / d2 …(1)F = ma = mg ...(2)mg = (G M m) / d2g = (G M) / d2 …(3)Where F is The force of gravity , G is gravity constant , M is the mass of earth , m is the mass of the object , d is the distance between earth & the object , a is acceleration and g is gravitationfrom equation 3 since (G) and (M) are constant it's clear that (g) depends only on the distance (d) between Erath and the object and do not depend on the mass of falling object.
