Who is the first Physicist to measure the gravitational constant G?
In 1789 Henry Cavendish measured G
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 does the proportionality constant k in coulombs law is huge in ordinary units whereas the proportionality constant g in newtons law of gravition is tiny mean?
It means that the force of electrical attraction (or repulsion) between two particles with units charges will be greater than the gravitational attraction between two particles with unit mass which are the same distance apart.
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 2.500 rounded to the nearest gram?
The answer depends on the units used for 2.500: pounds, milligrams, tons?
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.
If the intensity of light c the constant of gravitation g and the Planck's constant is represented as h is chosen as fundamental unit. Find the dimensions of mass length and time in terms of cg and s?
You can find the dimensions of derived units in the Wikipedia article on "Planck units".
What is Alpha Cassiopeia gravitational constant G?
There is no evidence to suggest that the gravitational constant 'G' is not the exact same number everywhere in the universe.
What are the units of gravitational constant?
There are two gravitational constants. The 'real one', the Universal Gravitational Constant, is always known as G. As its name implies it works everywhere. * The other one, acceleration due to gravity, is g. It is good only on our own planet. Units of g are m s-2 . Units of G are m3 kg-1 s-2 . *Some physicists are not quite sure about this. If one starts talking to you about "Planck-length gravity" you might want to remember an urgent appointment elsewhere.
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.
What is a measure of the gravitational force exerted on an abject?
Force gravitational = (mass of the object)(the gravitational constant) F=mg "g" is the gravitational constant, it is equal to 9.8 m/s^2
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
What is the symbol for gravitational constant?
An upper case (capital) G.
What is the gravitational formula for telling attraction?
The gravitational formula for telling attraction is given by Newton's law of universal gravitation: F = G * (m1 * m2) / r^2, where F is the gravitational force between two objects, G is the gravitational constant, m1 and m2 are the masses of the objects, and r is the distance between their centers.
Who is the first Physicist to measure the gravitational constant G?
In 1789 Henry Cavendish measured G
What is the SI unit of gravitational constant g?
It is m3kg-1s-2
