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.
Who find the value of gravitational constant?
Gravitational constant was determined by lord Henry cavendish in 1798 using a torsion balance .....G=6.67 *10^-9
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
Why is g called the universal gravitational constant?
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-2The 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 .
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 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 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 the SI unit for expressing gravitational force?
The "g". One g is the gravity on earth. The force of gravity on the moon is about 1/6 of a g. Since gravity and acceleration are indistinguishable, gravity can also be measured in the same units used for acceleration. For example m/s2 or feet per second per second. The SI unit for any force is the Newton. The value of g in SI units is 9.81 m/sec2, so the force on a mass m in kg is 9.81 x m Newtons
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 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.
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.
Which one of these is NOT an SI unit for density. kg over m3 g over cm3 g over mL or g over m2. Explain your answer?
The unit "g over m2" is not an SI unit for density. SI unit for density is kg/m3 or g/cm3 or g/mL, which all represent mass per unit volume. The unit "g over m2" represents mass per unit area, not mass per unit volume.
SI unit for measuring mass?
The SI unit for measuring mass is the kilogram (kg).
