The gravitational constant mentioned by Newton was measured at the end of the 18th century by Henry Cavendish (in the Cavendish experiment), using a torsion balance or pendulum designed by Mitchell which measured the force between suspended lead balls, which twisted (or applied torque) to a bar, the magnitude of which is proportional to the force applied. His intent was to detemine the specific gravity of the earth, but his notes indicate a value for G which differs by only about 1% from the value accepted today.

IS the gravitaional constant of moon is same as earth?
No, the gravitational constant on the Moon is not the same as on Earth. The gravitational constant depends on the mass and radius of the celestial body. The Moon has a lower mass and radius compared to Earth, resulting in a weaker gravitational constant on the Moon.
What is the constant in newton's law?
In Newton's law of universal gravitation, the constant is known as the gravitational constant, denoted as ( G ). Its approximate value is ( 6.674 \times 10^{-11} , \text{N m}^2/\text{kg}^2 ). This constant quantifies the strength of the gravitational force between two masses and is crucial for calculating gravitational interactions in physics.
What phase of the moon does it have the strongest gravitational pull?
The gravitational pull of the moon, on the earth, is almost a constant - whatever its phase.
What is the force with which a planets gravity pulls on something?
The force with which a planet's gravity pulls on an object is known as gravitational force, calculated using Newton's law of universal gravitation. This force depends on the masses of both the planet and the object, as well as the distance between their centers, described by the formula ( F = G \frac{m_1 m_2}{r^2} ), where ( F ) is the gravitational force, ( G ) is the gravitational constant, ( m_1 ) and ( m_2 ) are the masses, and ( r ) is the distance. On the surface of a planet, this force is commonly expressed as weight, which is the product of mass and gravitational acceleration (e.g., Earth's gravitational acceleration is approximately 9.81 m/s²).
Is thrust on the rocket in the absence of gravitational force of attraction constant?
Yes, the thrust on the rocket remains constant in the absence of gravitational force. Thrust is the force pushing the rocket forward, generated by the propulsion system. It is independent of gravitational force.
When was g the earth's gravitational constant calculated?
g, the force of the Earth's gravitational attraction, is not a constant.
Who calculated the Universal Gravitational Constant?
Henry Cavendish
Who measured the gravitational constant G?
Cavendish measured the gravitational constant "G".
Why did Einstein have to find a gravitational constant?
The gravitational constant was found by Newton, not Einstein.
Are gravitational constant and gravitational force the same thing?
No.
Why gravitational constant?
The gravitational constant was derived experimentally. Until recently, it was believed that it was a universal constant. However, developments in cosmological theories suggest the possibility that it is not a constant.
Who founded universal gravitational constant?
Sir. Isaac Newton discovered the formula with the universal gravitational constant.
What is the dimension of gravitation constant?
what is dimnsion of gravitational constant
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
IS the gravitaional constant of moon is same as earth?
No, the gravitational constant on the Moon is not the same as on Earth. The gravitational constant depends on the mass and radius of the celestial body. The Moon has a lower mass and radius compared to Earth, resulting in a weaker gravitational constant on the Moon.
When was gravitational constant found?
Although Newton included the gravitational constant in his law of universal gravitational constant, its value was not determined until some 70 odd years after his death, when Henry Cavendish measured it in 1798.
What is the formula for calculating weight when you know the mass?
Weight = Mass x (Local Gravitational Constant)/(Standard Gravitational COnstant)
