Explanation:
The Newton's Universal Law of Gravitation states that each mass particle attracts other mass particles. In simple words, it means that every particle in this universe has a tendency to attract other particles.
According to Newton, he had stated that the force of attraction between two objects is directly proportional to the product of their masses. It means that if the objects are having constant masses or unequal masses, their product of their masses would be directly proportional to the magnitude of the force.
Another statement states that the force between two objects is inversely proportional to the square of the distance between them. This means that the distance squared between the objects is inversely proportional to the force. Here the distance is squared because both the objects apply forces to each other ( collision force ). So, object A would apply a force to object B on some distance (d1). Object B would apply a force on object A on some distance (d2), and d1 is always equal to d2. So, it would be d1 * d2, which would be d squared.
So, we can frame a formula with the Gravitational constant, stating,
F = (G*m1*m2)/(d)square
So, your question was that what is Gravitational constant. In simple words, it is used as a constant of proportionality. This was first discovered by Lord Henry Cavendish by using a torsion balance. He saw that every particle or an object had a constant which had the same value, that is 6.67* 1/(10 raise to the power of 11) Newton meter squared per kilogram square, or 6.67*(10 raise to the power of negative eleven) Nm square per kg square. You see, it is the constant that is same in every place, particles, temperature, medium, etc., thus it is known as Universal Gravitational Constant.
In other words, Gravitational Constant is (numerically) equal to:
a) Magnitude of force of attraction between two masses of 1kg
b) The two objects are in a separation or distance of 1m.
So, if both the object masses are 1 kg, and the distance is 1m, the force of attraction will be equal to the Gravitational Constant. This is because if we follow this formula:
F= (G*m1*m m2)/(d) squared
It would be:
F = [(6.67*(10 to the power negative 11)*1*1/(1) squared
=6.67*(10 to the power negative 11)
This shows, F=G
Hope this clears your doubt. Thanks!
