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 .
Cavendish measured the gravitational 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
g, the force of the Earth's gravitational attraction, is not a constant.
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.
It is m3kg-1s-2
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
The gravitational constant denoted by letter G, is an empirical physical constant involved in the calculation(s) of gravitational force between two bodies
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.
Cavendish measured the gravitational constant "G".
The universal gravitational constant, which appears in Newton's Law of Universal Gravitation, can be used to calculate the gravitational attraction between any two masses, anywhere in the universe, not just here on Earth. Whereas the acceleration of gravity, g, is the specific acceleration caused by the planet Earth, at its surface where we live.
The gravitational constant denoted by letter G, is an empirical physical constant involved in the calculation(s) of gravitational force between two bodies
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.
g, the force of the Earth's gravitational attraction, is not a 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.
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
G is the universal gravitational constant. It is basically a conversion factor to adjust the number and units so they come out to the correct value. This is a universal constant so it is true everywhere.
The value of universal gravitational Constant(G) doesn't change it is constant at any place in the universe, it's value is 6.67259 x 10-11Nm2/Kg2 But the value of g varies from from place to place on earth,planet to planet and star to star because g=GM/R2 As G is constant g depends on M=mass of planet,R=radius of planet,so g varies with the change in M and R.
