Why g is called the universal gravitational constant.
Answer:
Because it's the constant in Newton's Law of Universal Gravitation.
It's "gravitational" because it is related to gravity; "universal ... constant" because it is the same in all cases.
"Universal" because it applied to the whole of the Universe.
Another answer. But, g isn't called the universal gravitational constant.
g is the acceleration due to gravity on our planet only.= 9.81 m s-2
The universal gravitational constant is G (often called big G ) = 6.673 x 1011 m3 kg-1 s-2.
It appears in Newton's equation f= Gm1m2 / d2 .

What apparatus was used by Cavendish to discover the universal gravitation constant?
The gravitational constant denoted by letter G, is an empirical physical constant involved in the calculation(s) of gravitational force between two bodies
Who measured the gravitational constant G?
Cavendish measured the gravitational constant "G".
When was g the earth's gravitational constant calculated?
g, the force of the Earth's gravitational attraction, is not a constant.
What effect of gravitational acceleration on Gravitational constant G?
The gravitational constant, G (big G), is a physical constant that doesn't change at all. The magnitude of gravitational acceleration, g (little g), has no effect on G.Little g is used as an approximation for near-surface gravity of a planet (or other large mass). The reason it is used is because the formula for universal gravity and Newton's second law:F = G (mplanet*mobject)/(r3) -- r is the distance between the centers of massF = mobject*aobjectyields (when set equal and dividing out the mass of the object): aobject = G (mplanet)/r3As you can see, the acceleration due to gravity won't change much for distances near the planet's surface. We call the above magnitude, g. Each planet has its own g and Earth's is about 9.8 m/s2.
What is the SI unit of gravitational constant g?
It is m3kg-1s-2
Why G is called universal constant?
G is called The universal gravitational constant because at any point of the universe the value of G is constant. G=6.67*10^-11 N m^2/kg^2...!!!!1
What apparatus was used by Cavendish to discover the universal gravitation constant (G)?
The gravitational constant denoted by letter G, is an empirical physical constant involved in the calculation(s) of gravitational force between two bodies
Proof of universal gravitional law where did come from ' G' value?
What does universal gravitational constant means?
The force of gravitational attraction between any two bodies, F, is given by the equation:F = G*M1*M2/r2 where M1 and M2 are the masses of the two bodies, r is the distance between their centres of mass and G is the universal gravitational constant.
Differentiate between universal gravitation constant abbreviated as G and acceleration due to gravity abbreviated as g.?
The universal gravitation constant (G) is a fundamental constant that appears in the law of universal gravitation, which describes the gravitational attraction between two objects. On the other hand, acceleration due to gravity (g) represents the acceleration experienced by an object in a gravitational field, typically near the surface of a massive body like Earth. The value of G is constant and the same throughout the universe, while the value of g can vary depending on the mass and radius of the celestial body.

What is G in physics and what is the value of G?
In physics, G usually refers to the gravitational constant, which is a fundamental constant that appears in the law of universal gravitation equation. The value of the gravitational constant is approximately 6.674 × 10^-11 m^3 kg^-1 s^-2.
When was g the earth's gravitational constant calculated?
g, the force of the Earth's gravitational attraction, is not a constant.
How was G measured?
The gravitational constant, G, was first determined by Henry Cavendish in 1798 using a torsion balance experiment. This involved measuring the gravitational force between two known masses and the distance between them to calculate G. The value of G is crucial in determining the strength of the gravitational attraction between objects.
Why is g called the universal constant?
It is the measure of the gravitational force experienced between any two bodies, anywhere in the universe. So, the same number is used to calculate the gravitational attraction between bodies anywhere in the universe. There are, however, some questions as to whether is is (or was) a constant over time.
What is the universal constant for gravity?
Gravity is proportional to the product of the masses, and inversely proportional to the square of the distance. The gravity constant is simply the proportionality constant. If you're calculating with all SI units, then the universal gravitational constant is 6.67 x 10-11newton-meter2/kilogram2
