What does Newton's universal constant mean and how is it used?

In summary, Newton's universal constant, also known as G, is a key factor in determining the strength of gravity between two masses. It is represented by the equation F_g = \frac{GMm}{d^2}, where M and m are measured in kg and d is measured in meters. The value for G, given as 6.67*10^-11 m^3kg^-1s^-2, ensures that the units cancel out and the final result is in Newtons.

Newtons universal constant is very complicated due to that i am new to modern Earth science i searched on the net and the results were countless here is the common answer
1-G=6.67*10(squared negative 11)m(cubed)kg(squared negative 1)s(squared)
someone please tell me what all this means and how to use it?
thank you all!

It is constant which determines how strong gravity is.

Newton's law of gravity says that the force of gravity acgting between two masses is equal to the the product of the two masses divided by the square of the distance between them multiplied by a constant. G is that constant.

This gives you the formula:

[tex]F_g = \frac{GMm}{d^2}[/tex]

The value for G given in your post is what you use if M and m are measured in Kg and the distance between them is measured in meters. The answer will be in Newtons.

There's a reason you have very strange units for G. The purpose off all the units is to make everything cancel out and give you a force in the end.
 

What is Newton's universal constant?

Newton's universal constant, also known as the gravitational constant or G, is a fundamental physical constant that appears in Newton's law of universal gravitation. It is a measure of the strength of the gravitational force between two objects.

What is the numerical value of Newton's universal constant?

The numerical value of Newton's universal constant is approximately 6.67430 x 10^-11 m^3/kg/s^2. This value is determined through precise experiments and is considered to be one of the most accurately known constants in physics.

Is Newton's universal constant the same everywhere in the universe?

Yes, according to Newton's law of universal gravitation, the value of G is constant throughout the universe. This means that the gravitational force between two objects will be the same regardless of their locations.

What are the units of Newton's universal constant?

Newton's universal constant has units of meters cubed per kilogram per second squared (m^3/kg/s^2). This unit is derived from the equation for gravitational force, F = G(m1m2)/r^2, where G is the universal constant.

What is the significance of Newton's universal constant in physics?

Newton's universal constant is a key component in our understanding of gravity and the motion of objects in the universe. It allows us to calculate the gravitational force between two objects and has been used to make accurate predictions and explanations in fields such as astronomy, astrophysics, and cosmology.
