What is the diffrerence bitween small g and big G in gravitation?

Answer 1

In gravitation, small ( g ) refers to the acceleration due to gravity at a specific location on the Earth's surface, typically around ( 9.81 , \text{m/s}^2 ). In contrast, big ( G ) is the universal gravitational constant, approximately ( 6.674 \times 10^{-11} , \text{N(m/kg)}^2 ), which quantifies the strength of gravitational attraction between two masses regardless of their location. While ( g ) is influenced by local factors like altitude and latitude, ( G ) is a constant that applies universally across the cosmos.
