Universal Gravitation Constant - HELP

Universal Gravitation Constant - HELP!

Hello, I'm a little confused...

What is the difference between the "Constant of Universal Gravitation" and the "Gravitational Force"? I know that there is a radius between two or more objects like the Earth and the Moon and bla bla bla... But the thing that I want to know is the "Constant of Universal Gravitation". Is it the force between the two objects??

I would be grateful if someone could answer my question!

Thanks!

Force between moon Earth and blah blah is

## F=\frac{Gm₁m₂}{d²} ##

F is the force. G is the universal gravitational constant

Force is variable (something you compute) depending on the masses and the distance between the masses. The constant is, well a constant.

But the thing that I want to know is the "Constant of Universal Gravitation". Is it the force between the two objects??

No, it's a universal constant, G ≈ 6.67 x 10^-11 Nm²/kg². See Gravity (HyperPhysics) and/or Gravitational constant.

Newton's law of gravitation essentially says that gravitational force between two bodies is proportional to the product of their masses divided by the square of the separation between their centres of mass (mM/r^2). G is the proportionality constant relating the magnitude of the force to mM/r^2. In math terms, G is equal to the Force divided by (mM/r^2).

The Universal Gravitation Constant, also known as the Gravitational Constant, is a fundamental constant in physics that is used to calculate the strength of the gravitational force between two objects. This constant, denoted by the letter G, is a measure of the strength of the gravitational force in the universe.

The gravitational force, on the other hand, is the actual force that exists between two objects due to their mass and distance from each other. It is calculated using the Universal Gravitation Constant and the masses and distance of the objects.

In simple terms, the Universal Gravitation Constant is like a "conversion factor" that allows us to calculate the gravitational force between two objects. It is a fundamental constant that helps us understand and predict the behavior of objects in the universe.

I hope this helps clarify the difference between the Constant of Universal Gravitation and the Gravitational Force. If you have any further questions, please don't hesitate to ask.
