### 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 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 is one G?

The g (pronounced /&#712;d&#658;i&#720;/) is a non-SI unit equal to the nominal acceleration of gravity on Earth at sea level (standard gravity), which is defined as 9.80665 m/s2 (32.174 ft/s2). The symbol g is properly written both lowercase and italic to distinguish it from the symbol G, the gravitational constant and g, the symbol for gram, a unit of mass, which is not italicized From Wikipedia

### What is G in physics and what is the value of G?

Among other things, it may refer to the gravitational constant - the constant of proportionality for the universal law of gravity. In SI units, it's magnitude is 6.67 x 10-11 m3kg-1s-2.

### How gravity of planets calculated?

The forces are calculated from Newton's theory. F = G M1 M2 / R-squared. IN the formula M1 and M2 are the masses of the Sun and the planet and R is the distance. G is the gravitational constant, and in SI unit it is 6.670E-11 so that if the masses are in kilograms and the distance in metres, the answer is in Newtons.

### 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 attraction between two objects is: G x m1 x m2 / distance squared where m1 and m2 are the two masses involved, and G is the gravitational constant - approximately 6.674 x 10 to the power -11, in SI units.

### What is the formula to solve for gravitational potential energy?

Formula for Gravitational potential is - G M / r Here G is universal Gravitation constant, M - mass of the planet and r is the distance of the point from the centre of the planet. The unit is J/kg If potential energy is needed then the potential is to be multiplied by the mass m. So gravitational potential energy = - G M m / r So the unit would be J (joule)

### Who is the first Physicist to measure the gravitational constant G?

In 1789 Henry Cavendish measured G
