According to Newton’s Universal Law of Gravitation, the gravitational constant (G) value is 6.67×10 -11Nm2/kg2. This means the force of gravity is very weak at a small scale, and the value of G is minimal. It is measured in units of Newton meters squared per kilogram squared (N⋅m²/kg²). In 1798, British physicist Henry Cavendish measured the value of G for the first time accurately.
The gravitational constant (G) is a key concept in physics that helps explain how gravity works at both small and large scales. Its precise value allows scientists to calculate the force of gravity between objects and understand the behavior of everything from the falling apple to the motion of stars and galaxies
