Question

Why is G called the universal gravitational constant?

Answer 1

1. The universal gravitational constant (G) is a constant of proportionality equal to the force of attraction between two objects of masses 1 kg each and are separated by a distance of 1 m.
2. The value of G has magnitude only.
3. Its value is the same for all heavenly bodies.
4. Its value is constant even in all the places on the surface of the earth. The value of G is 6.67 x 10^-11 Nm² kg^-2.
5. Hence, it is called the universal gravitational constant.
